GapMaster + KMS

GapMaster is the world’s leading adjustable anvil system for accurately adjusting the depth of cut while presses are running.

Based on an anvil cylinder, the system adjusts the gap between the anvil cylinder body and the magnetic or cutting cylinder in ultra-precise steps, even while the machine is running.

Kocher+Beck has continuously developed and expanded the GapMaster range so that it can be used on different types of machines.

The latest development is the GapMaster MF (Maintenance Free). With this version, no lubrication unit or grease lubrication is necessary, as the GapMaster MF is equipped with maintenance-free bearings. This version is available for almost all versions of the GapMaster.

GAPMASTER STANDARD

Providing perfect results on even the thinnest of substrates.

Overview:

With the GapMaster, the gap dimension can be adjusted in the range of ± 0.1 mm, by adjusting the air gap in increments of 0.8 µm. The permanent, high-precision adjustment reduces the wear of the cutting tool and significantly extends the service life.

This enables the machine operator to precisely control the cutting depth, which is particularly important when cutting down to the thin carrier foils that are common today.

In addition, the same die-cutting plate can be used on substrates with different thicknesses, such as glassine or plastics.

Permitting generous, fast adaptation to all common standard materials without the costly replacement of cutting tools and eliminates all the disadvantages of a fixed gap system.

Lubrication can be either grease, oil, oil-air or maintenance-free (MF).

Adjustable separately on the operator or machine side and compatible with a wide range of machine types.

Benefits:

  • Easy adjustment for the perfect cutting depth
  • Independent adjustment on both sides
  • Adjustment range ± 0.1 mm, other adjustment ranges possible
  • One cutting tool can be used for substrates of different thicknesses
  • Reduced machine downtime
  • Extended service life of the cutting tools and the cutting unit

GAPMASTER IC

A fully integrated GapMaster installation system ready for immediate use.

Overview:

With the GapMaster IC (Integrated Control), the adjustment unit is integrated into the operator-side sliding block. This means that the GapMaster IC can be removed and installed very easily by the customer using the lifting beam supplied.

Suitable for top and bottom cutting.

Lubrication can be either grease, oil-air or maintenance-free (MF).

Separately adjustable, operator-side or machine-side, and compatible with a wide range of machine types.

Benefits:

  • Adjustment unit integrated in the sliding block
  • Quick removal and installation
  • Independent adjustment of both sides
  • Lubrication variants: Grease, oil-air, maintenance-free
  • Top and bottom cutting possible
  • Extended service life of the cutting tools and the cutting unit

GAPMASTER FR

For use in cutting units without support shafts/support rollers.

Overview:

The GapMaster FR (Free Running) is specially designed for operation in cutting units without support shafts or support rollers.

Free running operation is made possible by larger axle journals and correspondingly large and robust sliding blocks.

The cutting forces are thus transmitted directly into the unit frame.

Lubrication can be either grease or oil-air.

Separately adjustable, operator-side or machine-side, and compatible with a wide range of machine types.

Benefits:

  • Suitable for punching units without support shaft / support rollers.
  • Larger axle journals / more robust sliding blocks
  • Lubrication options: Grease or oil-air
  • Extended service life of the cutting tools and the cutting unit
  • Independent adjustment on both sides

GAPMASTER MAGNETIC

Ideal for cutting units that do not allow a GapMaster in the counter punch position.

Overview:

The GapMaster Magnetic is only suitable for unchangeable magnetic cylinder unwinding (semi-rotary machines).

In this case, the cutting plate is mounted on the GapMaster.

Lubrication can be carried out either with grease or maintenance-free (MF).

Benefits:

  • Only for fixed-format, semi-rotary cutting units
  • Lubrication variants: Grease, maintenance-free (MF)
  • Independent adjustment on both sides

KMS PRESSURE MANAGEMENT SYSTEM

Accurate measurement of cutting pressure.

Overview:

KMS 2 / KMS 3

KMS is a universal, high-precision hydraulic pressure measuring system for setting the pre-tensioning pressure of the components of a rotary cutting unit.

The current cutting pressure is displayed on the pressure gauge in kN and bar. The measurements are taken at the point where the force is transferred to the cutting tool.

The system immediately displays the current cutting pressure and also pressure changes, e.g. due to thermal expansion, so that you can adjust the cutting pressure accordingly. You can also detect concentricity fluctuations on the cutting tool and counter punch cylinder as well as defective bearings. This way you can eliminate these problems early on before they cause damage. A correctly adjusted cutting pressure protects both your tools and the bearings of the unit and extends their service life.

Benefits:

  • Precisely detectable pressure rises
  • Precise pressure control of the operator and machine side of the cutting unit
  • Suitable for all common rotary cutting units
  • Minimal installation, no wiring required and fast quick adjustment (clamp-fix) available

Overview:

KMS 4

The KMS 4 pressure measurement system is the first choice for special die-cutting applications such as brochures, cardboard, heavy and fibrous materials.

As with the KMS 2 and 3, the actual cutting force is displayed on the pressure gauge in kN and bar. Measurement is taken at the point where the force is transferred to the cutting tool.

The KMS 4 can be operated with a pressure of up to 1000 bar, and we would be happy to discuss your individual requirements to find the right solution for your application.

Benefits:

  • Highly stable overall system
  • Special die cutting applications
  • High pressure
  • Quick adjustment (clamp-fix) possible
