Granulators for edge trims

For the disposal of edge trims at extrusion lines and rewinding systems we equip the granulators with infeed systems. The infeed rollers can be designed:

  • smooth (standard)
  • knurled or
  • grooved

They are wear protected in all versions.

For simple applications, the infeed systems can be equipped with rotary field magnetic motors. For applications with higher line speeds, we link the infeed speed with your line speed. The additional speed adjustment guarantees a very reliable operation and does not influence the extrusion and trim cutting process.


High efficiency

  • opening of infeed and cutting chamber without tools
  • screen holder removable
  • low cleaning time due to smooth, all-side machined surfaces
  • high energy efficiency due to cutting geometry and EnergySave motor controller

Excellent regrind quality

  • scissors cut with constand cutting circle
  • stationary blade is mounted against hardened stop
  • rotary blades adjustable outside of the granulator
  • sealed design and low rotor revolution ensure quiet operation and low-dust regrind

High operational reliability

  • separate infeed systems for each edge trim
  • controlled adjustment to line speed for constant draw
  • adjustable strippers prevent windings
  • synchronous running of both infeed rollers

Individual features

  • water cooled cutting chamber for temperature-sensitive material
  • infeed rollers with different diameters and surfaces
  • stand alone solution or integration into the production line

Various rotor versions, drives and blade qualities are individually designed for your application, grinding reliably, energy-saving and producing an optimum grinding material quality.

Suitable wear protection packages secure your investment, reduce your maintenance costs and increase your profit when grinding abrasive materials.

Water-cooled cutting chambers and cooling-air supply reduce the thermal stress on your materials, protect against plastification in the cutting chamber and enable optimum grinding even in critical applications.

Maximum energy efficiency thanks to the latest design, drive motors in the energy efficiency class up to IE 4 and the use of GETECHA EnergySave, a system that significantly reduces your power consumption under partial load.

Electrical accessories from GETECHA connect your rotary cutter to the peripherals, control upstream and downstream units, create safety and increase your productivity. If you need special equipment and cannot find it anywhere, please contact us.

RS 2404 with double infeed

For each edge trim one infeed system-
different speeds of the edge trims are thus compensated.

RS 2404-E

Simple design – the feed rollers are grooved to compensate for different thicknesses of the edge trims. A spring-actuated flap on the feed hopper switches off the infeed, if the pull on the edge trims is too high.

RS 3004-2E with special dancer arm
RS 3004-E2

The dancer arm controls the tension on the edge trim and prevents it from tearing off.
