Wohlenberg High-Speed Guillotines of the pro-tec product line are of solid construction and suited for processing various materials, as e.g. paper, cardboard, offset printing plates or similar cutting stock. Modern cutting technique allows rational cutting of different products and sizes.
The guillotine can be economically used as stand-alone unit or integrated in cutting systems. Program generation is menu-guided and covers a variety of cutting jobs, e.g. Single cut, Program cut, Repeat cut, Clamping without cut, Automatic actual-value transfer.
on thin boards
with high-precision and easy handling.
Quick positioning of cutting stock in between 30 cm / sec and 200 cm/sec. (backgauge return mode of system machine with linear drive). Backgauge-speed - acceleration and breaking - are adjustable, which is particularly advantageous when processing sensitive cutting stock.
Unnecessary waiting times are eliminated, the cutting cycle speed is increased by over 30 %.
With clear visualisation of the selected and actual clamp pressure on the display.
No extreme overlcamping of the small sides of the ream, which results in a longer knife life time and higher cutting accuracy. The clear visualisation on the display keepts the operator informed about the actual clamping pressure.
The knife-change protective device provides highest safety standards for the machine operator. Knife chipping during the knife-exchange have been eliminated.
New knife-changing device (knife lift with setting gauge) with automatic knife fine-adjustment. Adjusting of the knife carrier and switch-off of main motor are not necessary (Correction of knife thickness +/- 0,99 mm).
The torsion-free cutting unit is perfectly suited for heafy loads, guaranteeing highest cutting accuracy for decades.
with smooth engaging of the main drive, protecting the mechanics and transmission.
The clamp bar stops close to the material, significantly reducing cycle times.
2 mm stainless-steel plating on the machine table virtually eliminating the possibility of corrosion.
The basic principle of the control is the manual input via the large 18,4 inch touch-screen, dispensing with the need for additional electronic or mechanic controls. The distances on the screen are minimised for the user, and are logical with few image changes. Only currently relevant and executable actions are displayed.

A virtually inlimited number (up to 1.000.000) of programs can be stored. Each machine is equipped with an extensive language package. Further language versions are available on request.
An existing MIS system can be operated in the machine display via a browser based connection.
Low cost, standard USB memory sticks are used for the transfer of cutting program data, backup of your stored programmes and for "off-line" reading of CIP 3 (PPF) and CIP 4 (JDF) files.
For "online" reading of CIP 3 (PPF) and CIP 4 (JDF) files. And for the connection to an MIS system.
High operating reliability. power failures cause no problems.
The CIP-data-module generates a cutting programme including graphicals visualisation in a matter of seconds. The pre-press data is recalled on the guillotine itself, with a push of a button the guillotine creates the cutting program in a few seconds - an additional PC is not required.
A software running on a external PC which allows the oeprator to create the program in an interactive way from a CIP 3/4 file. So the operator can decide the order of cuts manually, according to his own needs.
A pre-requisite for an angular precise cut is an even clamping over the entire surface to be clamped. To guarantee this the pressing cylinder of the new Wohlenberg is installed centrally underneath the cutting table. Via two solid deflector levers the clamp bar is pulled down onto the cutting stock providing an equal an strong pressure on both sides.
2 mm stainless-steel plating on the machine table virtually eliminating the possibility of corrosion.
In order to precisely control the clamp bar movement, the Wohlenberg high-speed guillotines are equipped with new-type kinematics. The foot lever position is directly transferred to the clamp bar, allowing a smooth lowering without shifting the upper sheets.
A further basic requirement is a geometrically perfect machine. The side gauges of the new Wohlenberg are from extra thick-walled aluminium. Only when registering the cutting stock against totally perpendicular side-gauges, a precise, square cut-result can be expected.
Backgauge drive by means of a precision transport spindle which is precisely linked with a solid circular guide. This guide is able to take up high forces with low lsos. Should the operator accidentally knock against the backgauge too vigorously, this would not cuase any defelction of the backgauge. With this high precision drive, it is possible to move the backgauge 1/100 mm back or forwards.
The air table blower is activated only, when required during the cutting program, thus saving energy, noise and heat.
For comfortable and easy turning even of heavy reams, the machine table is closed, forming a strong air-cushion. The elimination of the slot gap means no air cushion erosion and no trapped or forlded sheets on the bottom of the ream.
As the main drive a large spur gear is installed on the new Wohlenberg machine. This is less prone to damage as for example a worm gear and also required less energy.
The cut release is activated by a two-hand cut-start. The down-movement of the knife is immediately stopped when one of the buttons is released. The self-monitoring light barrier with 50 channels operates fully electronically and is maintenance-free.
It is constantly activated and subject to a check before each cut. The mechanical safety bolt is an additional feature against doucle-cycling of the knife. All machine functions are monitored and in case of malfunction described on the display.
The cutting line light with LED is lasting extremely long. No exchange of the bulbs necessary.
The machine table is equipped with micro-air-nozzles (instead of ball-nozzles). The result is an optimised air-cushion.
Chips are disposed of underneath the front-table. Disposal of sharp-edged chips without any risk of incuries (e.g. aluminium chips). The Wohlenberg automatic waste disposal edevice is an effective rationalising measure, increasing the productivity of the guillotine by approx. 30 %. To collect small cuts on the front table, the ASE can be lowered up to 4 mm. The quick opening- and closing movement of the table is motorically driven, the vertical movement is effected pneumatically.
For easy unloading of the front-table without interfering with the cuts on the rear-table of the cutter.
A downholder is gently fixing the pieces in front of the knife during the cut. A sheifting and moving of small pieces (business-cards e. g.) during the cut is avoided.
Compressed air is blown through small nozzles onto the blade to get rid of small waste pieces, which might stick to the blade.
For sensitive material like plastic; the knife-speed is infinitely adjustable.
The clamp is equipped with high-tech silicone-felt, which cleans the back-side of the knife permanently.
For small cutting stock, e.g. business cards.
The newly developed retractable side-gauge is firmly fixed to the guillotine and aligned parallel.
The moveable rear-table protection is monitored electrically. The operator has an easy access to clean the knife's rear-side. For safety reasons, both the knife and the backgauge motion is locked during this process.
Motor-driven correction of over and undercut (tilting function). Aligning of the printing image parallel to the cutting line (swivelling function).
The larger depth of the clamp beam improves the cut-accuracy on slippery and / or wavy material.
This allows a two-point aligning on the long-side of the ream and a one-point aligning on the short side (same principle as in the press). This is essential if the sheets are convex - as there is in this case no straight edge for alignment.
The turning gripper turns the ream automatically. It can be turned by 90 ° (to the right or left) and by 180 °. it is also possible to unload a four-side-trimmed-ream automatically via a Baumann unloader. The BDG is available for Wohlenberg 132, 168 and 225.
This is a special, low-cost version of the BDG. Turning of the ream by 90 ° only and only to the left (left-lay, only). Automatic unloading via an unloader is not possible. Available for Wohlenberg 132, 168 and 225.
For rear-table loading, we provide an exceptionally quick linear drive. This reduces the time required to complete the backgauge-travel to the rear-loading position to a minimum. The backgauge travels over a magnetic field. Its position is permanently controlled and re-adjusted, if necessary. This backgauge-drive technology is able to cope with even strong impacts against the back-gauge.
Storage space for your knives and a table to prepare / clean the knives. Moveable or stationary.
