EHD Series

Often called “the workhorse of the industry”, the Kluge EHD is already a legend. Featuring speeds up to 3,300 impressions per hour, the EHD now comes with delayed delivery allowing it to accommodate sheets up to 17″x 24.75″ (431mm x 628mm), with up to 40 square inches of die area. Kluge’s patented Delayed Dwell technology allows the EHD to start on impression sooner, bottom out, and remain on impression longer­ doubling impression time with no loss of production speed and assuring flawless foil separation from the stock. A new, optional, freestanding mobile electronics console puts all press operations in one place for easy access. The same console can also serve as a workstation and toolbox.

Rugged, dependable and simple to operate, the EHD is known for providing years of reliable service in foil stamping, embossing and die cutting, and for over 25 years has been the standard by which all presses in its class are measured.

All Kluge presses can be supplied with the electrical specification of your country.

Delayed Delivery – Allows stock greater than 14″ to be run on the EHD
Mechanical Foil Control System - Allows for a wide array of foil draw and coverage with highly accurate registration between images

Benefits

  • Three-draw system
  • Air blast system

Outline
The press comes equipped with a three-draw mechanical foil control system (MFCS) as standard. This configuration allows for a wide array of foil draw and coverage with highly accurate registration between images. All Kluge foil control systems utilize an air blast system to assure the foil relay from stock between impression.


Toggle Base and Die Heating Plate - Enables an infinite range of secure die mounting. Includes two heat zones

Benefits

  • Two thermostatic heat controls
  • Infinite die mounting positions
  • Optional lightweight grid-etched model available

Outline
The Kluge toggle base features a honeycomb design, enabling an infinite range of secure die mounting positions. The die heating plate (or hot plate) has two independently-controlled thermostatic heat zones for controlling the temperature of the dies mounted across the press ‘live’ area.

An optional upgrade to the standard Kluge toggle base is available to facilitate easier and quicker make-readies. The lightweight model is laser-etched with a layout to match the corresponding grid on the platen, enabling quick and accurate die placement. Weighing only 14lbs (regular weight 40lbs), operators also benefit from the lightweight model requiring less effort to mount the toggle base to the press.


Micro Adjustable Gauge Band – Precisely adjust the gauge band for sheet placement
Delayed Dwell System - Increase impression time without decreasing operational speed

Benefits

  • Greater foil coverage
  • Increased production speeds
  • Reduce make-ready time

Since foil coverage is a function of pressure, heat and time, a longer dwell time at a higher dwell impression force will result in greater foil coverage and higher production speeds on many products. We have seen jobs produced that previously could not be produced and make-ready time greatly reduced on tough work.

Faster and simpler conversion from solid arm operation to dwell arm operation saving valuable make-ready time and money. The previous design was time consuming and, in many cases, jobs that would have been produced more efficiently with the dwell arms were not. The simplicity of this design will increase the use of the dwell feature.

Outline

The latest generation of dwell side arm is an immense improvement over the original design. The solid arm operation achieves an impression from the physical interference, between the platen and the bed, during each cycle. The impression dwell, in both the old and new design, is accomplished by introducing heavy spring force in addition to the physical interference and extends the total time of impression at the magnitude of the spring force. The difference between the two designs is the means by which this is accomplished.

The original design required that the platen is raised and a spacer at the springs would be removed before the two springs could come into play and introduce dwell in each impression. One might say that the stroke had to be shifted to allow spring action.

The new patented design, which includes three springs of greater force, simply compresses the springs for solid arm operation and relaxes the springs when dwell is desired. In this design, the stroke is not changed. Turning the dwell “Off” and “On” is accomplished by adjusting the nut on the end of each arm to line up two marks. By virtue of design, the resulting dwell time is longer than the older style arms.


Delivery - With receding stacker table. Will not mar stock and gives the operator accurate press usage

Benefits

  • Four-finger delivery arm
  • Receding pile delivery table

Outline
The Kluge delivery system utilizes a four-finger delivery arm operating on a straight-out motion. Combined with a receding pile delivery table and impression counter, the Kluge EHD will not mar stock and gives the operator accurate press usage.


Dual Set Point Temperature Controls - Provides operator with two temperature setting options - one for standby temperature and one for operating temperature

Benefits

  • Strandby and running temperature controls
  • Electronically controlled

Outline
The hot plate temperature controls on Kluge presses are available with dual set points. These provide the operator with a standby temperature and a running temperature. This is beneficial when the press is started. As heat is transferred from the die to the paper stock, a higher temperature setting is required to keep the die at a constant working temperature. If this high temperature is maintained when the press is left unattended, such as during a lunch break, the die will usually become so hot that is will scorch the foil. A general solution to this would be to cycle the foil out of the press when it is not in use, however, the die will still retain enough heat to cause a change in quality when the press is again put into continuous production.

The dual set point temperature controllers set with a low standby temperature, automatically changes to the second set point when the press is started, making the transition from standby to operation with minimal effort.

Consistent high quality work can be easily achieved with dual set point temperature controls for the standby temperature and operating temperature settings.


Feed Without Impression Control – Allows setup of feed and delivery without risking valuable dies and wasting expensive foil
Impression counter – Will only count the number of impressins for easy totalling of completed stock
Rotary Vacuum Pump – Allows independent control of the delivery vacuum
Auto Lubrication System – Provides hands off worry free lubrication of critical press bearings
Three-Nozzle Air Blast Foil Release – Separates foil web from the stock for improved product quality and increased productivity (requires separate compressor or air system)
Complete Guarding with Electric Interlock System – Meets rigorous safety standards yet provides access to press
Variable Pitch - Feature of the standard Kluge magazine that enables the press to feed stocks of varying thicknesses (e.g. envelopes, single panel pocket folder)


Our line of 14 x 22 presses include a unique standard feature that increases productivity for stock types that are thicker (or double thickness) at one end while thinner at the other. Job types that feature these characteristics include envelopes, single panel folders etc. When stacked, the thickness difference in these types of products are multiplied and the pile does not stand evenly when loaded into the magazine. This leaves a tapered pile that is extremely difficult to load, especially with larger quantities of stock. All Kluge standard feeders on our line of 14 x 22 presses include our unique “Variable Pitch Feature”. Here the stock back supporting plate of the magazine can be disengaged from its fixed position and locked into variable pitch mode. While in variable pitch mode, the back plate is titled to compensate for uneven stock at the feeder (or front) end of the pile. This enables the feeder arm can easily pick up the next sheet as the stock is positioned parallel to the sucker tips. As the stock pile is used up the back plate gradually tilts to an upright position to maintain accurate compensation for the irregular stock thickness.The video here is a quick demonstration of how the Variable Pitch feature works. The back plate is manually advanced and reversed to clearly show the mechanism. To see the feature with stock loaded and in production see below.

Hologram Registration Unit - Provides the technology for registering holograms on the EHD


Since the early 1980’s when hologram technology progressed to foil stamping machines, the use for holograms has become more and more wide spread. Today the hologram has a whole range of uses from security tags to packaging, book covers and advertising. The video here demonstrates registering a hologram as part of a seven pass colorful foil/hologram display card. Read on to learn more about Kluge’s hologram registration technology and capabilities.The Kluge Hologram Registration Unit is built onto the Electronic Foil Control System, Low Mount. It enables you to accurately register holograms using your Kluge press. Note: the hologram registration unit is not compatible with the mechanical foil control system. The Hologram Registration Unit utilizes fiber optic technology as the hologram registration mark detection system. The fiber optic sensor is mounted to the toggle base in line with the edge of the foil. The sensor is connected to the signal pick up device, also known as the ‘amplifier’ which is then electronically adjusted until the registration mark can be seen. This innovative system allows you to digitally align hologram foil on the die with registration accuracy of +/- .012″. Two #30 gauge wire guides are positioned on the toggle base just below the die, one is placed under the foil and the other is placed over the foil. These wire guides effectively prevent the hologram foil from curling as it is fed through the machine (see photo).Easy access to the configuration and controls of the Hologram Registration Unit is made available from the touch screen control system.Kluge has developed a “User Guide to Hologram Stamping”.

Adjustable Impression - Decrease make-ready time. Impression can now be infinitely adjusted with the simple turn of a handle

Benefits

  • Decrease make-ready time
  • Reduce production costs
  • Infinite impression adjustment

Outline
Until now, adjusting the platen bolts and/or adding packing behind the make-ready plate has been the make-ready process for impression adjustments on Kluge presses. Adjustments to the platen bolts are cumbersome and time consuming. Each bolt has to be adjusted equally to maintain as close to level as possible. Because of the inherent design, when raising the platen to increase pressure the platen is put out of parallel with the bed slightly creating more pressure toward the bottom of the platen.

Adding packing is limited by the various thicknesses of the available packing and therefore not infinitely adjustable. When adding spot packing, the carrier sheet used would increase the impression to the whole image as well as the spot. In short this make-ready procedure is very time consuming and requires much skill.

The new adjustable impression design works on the principle of adjusting the impression by shortening or lengthening the side arms. The adjustment is made by simply turning a crank handle and both side arms are simultaneously adjusted equally. Total adjustment is .144″ (just over 1/8 inch) and equals12 flats or 2 revolutions of the platen screws. The adjustment is infinitely variable and not in steps as is packing. Parallel of the platen to the bed is not affected. Of course, spot packing will still be necessary but the affect it may have on the rest of the image will be easily rectified by backing off the impression with the adjustable impression. If, while running a job, the impression diminishes a simple turn of the handle gets you back in business.

This new design has been coupled with a recently released new dwell side arm design. This new patented design offers a longer dwell time at a higher dwell impression than the previous design resulting in more foil coverage and higher production speeds on many products. In addition, the simple switch of this design from dwell to non-dwell operation will save time and greatly increase the use of the dwell feature. The design incorporates spherical bearings at the back shaft, which are more forgiving and, therefore, will offer longer life.

In short, this new development will greatly decrease make-ready time, take much of the required skill out of the press operation and will result in reducing the costs associated with both of these production challenges.


Mechanical Jogger - Prevents a saw-toothed edge on your finished pack

Benefits

  • Four-finger delivery system
  • Impression counter
  • Maxiumum capacity: 14′ (365 mm)

Outline
The mechanical jogger prevents a “saw-toothed” edge on your finished pack by pushing each sheet (as it lands on the delivery table) into a straight pack. This makes for easy reloading on second runs and facilitates faster packaging.


Preload Magazine - Allows you to reload the press with new stock while the press is running

Benefits

  • Increase production speeds
  • Reload while the press is running

Outline
The preload magazine allows you to reload the press with new stock while the press is running, therefore less down time and higher production speeds. Perfect for long runs such as greeting cards or book covers.


Two-up Feeder - Allows the EHD to run Two-Up on certain jobs


By design all of our platen format, sheet-fed presses are capable of feeding irregular shaped stock and can be configured to feed “multiple-up” sheets. With a small supply of additional accessories, this method enables smaller jobs to be fed two sheets at a time, thereby doubling production speed. Other uses for the two-up attachment include: Run pass one of a two pass job on one side of the machine while pass two is run on the opposite side of the platen OR skilled operators could set up two unique jobs to run simultaneously on the press! Imagine the time savings you could enjoy here. The video demonstration here shows foil stamping and embossing two-up playing card boxes on our EHF Series Press.


Electronic Foil Control System - Increased impression accuracy when foil stamping

Benefits

  • Easier to operate
  • Less foil reloads
  • Greater image stamp accuracy
  • Touch screen control

Outline
Designed to be even more operator-friendly by making the foil unwind and rewind shafts more accessible to the operator.

The unwind and rewind shafts are staggered, making it easier to observe the unit while in operation. The foil unwind shafts are designed to accept 7 inch diameter foil rolls for longer runs between foil reloads. In addition, the mounting system for the unwind shafts has been strengthened to minimize the shake that naturally occurs from the action of the press.

From the beginning, the accuracy of the gap, between image stamps on the foil, has been the number one goal of the Kluge Electronic Foil Control Systems. Greater accuracy allows for maximum foil savings without worry of a bad sheet. This new unit incorporates a stepper motor control system that can control motion to within .001″. This allows the unit to hold a tolerance as close as +/- .016 ” at the foil gap making the potential for a quick payback through foil savings a reality.

Is available with (up to) four separate draws – each capable of alternating the sequence operation.

Additional draws (up to a total of four) can be added in the field.

An optional foil seam skipper feature is available for non-registered holograms. The foil seam skipper ensures that the seam is never stamped on the product and is successful in doing so with minimal waste.

Unlike some other foil control systems on the market, each foil draw includes it’s own separate rewind shaft.

A foil detector is available, as an option, which stops the press when the foil runs out. This allows the operator the time to attend to other important details.

A friendly and contamination-resistant touch screen achieves operator interface. It is available in inches or millimeters and English or Spanish. The touch screen control can be located in the operator side swing guard or in a movable control console that includes tool drawers and a work surface.

This unit comes standard with storage memory of 25 separate foil draw lengths for recurring jobs. The press operator can simply call up, by number, a previous run job. Or, if a previous job was similar, it can be called up and modified, thus saving valuable set-up time in either case.


Reversible Register Cam - Saves time in make-ready when adjusting side registration

Benefits

  • Reduce make ready time
  • Effortless side registration adjustment

Outline
The Reversible Register Cam is time saving feature from Kluge that makes switching between gear and operator side registration a breeze. Before introduction of this feature, press operators needed to remove the entire cam and replace it with the opposing cam in order to switch sides for registration. The difficult-to-reach location made changing from one cam to the other a time consuming task and springs and nuts were often dropped or lost under the press, further increasing down time.

The left and right side register cams are mounted together on a spring loaded wedge body that enables you to switch side guides quickly. By pulling out, turning 180 degrees and releasing, the reversible register cam effortlessly switches from gear to operator side registration and visa versa in only 3 seconds. What’s more, the switch can be made without the need for tools, speeding the process even more.


Variable Speed Control – Control press speed with greater accuracy
Dual Foil Rewind - Provides smooth rewind operations for different, multiple draw lengths or waste foil diameters

Benefits

  • Increase production speed
  • Reduce clean up time

Outline
The Foil Rewinder automatically winds the used foil onto a roll at the rear of the machine after impression. This makes for easy clean up and foil change when switching or completing jobs, facilitating increased production speed.


Filler Plate – Replacement for die heating plate when die cutting
Missed Sheet Detector – Prevents die, make-ready and press damage
Foil Detector – Stops the press when a roll of foil is empty
Lightweight Grid-etched Toggle Base - Gridded construction for greater accuracy in the die make-ready and weighs only 14lbs

Benefits

  • Accurate die placement
  • Lightweight (14lbs)

Outline
The lightweight grid-etched toggle base enables the operator to quickly and accurately align the die(s) on the toggle base during make-ready. The laser-etched grid is labelled numerically on the horizontal axis, and alphabetically on the vertical axis. The grid is replicated on the platen.

To facilitate make-ready further, press operators benefit from the light weight of this model. Weighing only 14lbs compared to the 40lb standard toggle base, less effort is required to mount the toggle base to the press.
