Slitting shears with tool change turnstile

Function and task:

The slitting shear cuts and/or edge-trims bands by means of cutting tools using pre-set strip widths. 
The cutting tools on the knife shaft of the slitting shears can be replaced with a new one very quickly thanks to the pre-loaded tool on the tool change turnstile. The replacement is done by means of a pusher plate system.

  • Strip thicknesses of 0.1 to 6.0 mm
  • Cutting depth adjustment by electric motor
  • Tool clamping by means of hydraulic nuts
  • Automatic cutting tool change under 7 minutes
  • Pre-loading various cutting tools
  • Can be combined with tooling robot

Edge trimming shears

Function and task:

The edge trimming shear cuts off damaged edges of the bands with utmost width precision and minimum burr. The cut off edge scrap is fed to a scrap cutter or scrap baller via scrap chutes.

  • Strip materials such as steel, stainless steel, aluminium, copper and their alloys with strengths of up to 1,000 N/mm2
  • Strip widths over 2,400 mm
  • Strip thicknesses of 0.1 to 8.0 mm
  • Strip speed up to 1,200 m/min
  • Cutting gap and cutting depth adjustment by electric motor
  • Regrinding of the blades at the circumference or at the end section

Scrap baller/chopper

Scrap baller

Edge scrap from the edge trimming process is coiled in a scrap baller and condensed to a solid scrap coil.

  • Strip materials such as steel, stainless steel, aluminium, copper and their alloys with strengths of up to 1,000 N/mm2
  • Common edge scrap widths 3 to 50 mm.
  • Baller can be set up under the floor or on the ground with automatic feeding of the edge scrap


Scrap chopper

The edge scrap from the edge trimming process is cut into small pieces in a scrap chopper.

  • Strip materials such as steel, stainless steel, aluminium, copper and their alloys with strengths of up to 1,000 N/mm2
  • Strip widths in excess of 2,400 mm
  • Low-noise chopping
  • Cutting gap adjustment by electric motor
  • Two blades per knife
  • Regrinding of blades on conventional surface grinder

Cut-to-length shear

Eccentric shears

The eccentric shear continuously cuts through-passing slit strips thus producing blanks of identical dimensions. Cutting tolerances are reduced to a minimum.

  • Strip materials such as steel, stainless steel, aluminium, copper and their alloys with (yield) strengths of up to 1,000 N/mm2
  • For strip widths in excess of 2,200 mm
  • Different version for strip thicknesses from 0.1 to 8 mm.
  • Continuous cutting of strips for band speeds from 30 m/min to 120 m/min
  • Section lengths from 300 mm to over 14 m
  • Available for 90° cuts or as swivel shears for trapezoid, triangular, arc or profile cuts
  • Shears have their own PLC with interfaces to various bus systems (interface to other line components)
  • Vector-controlled drives to ensure minimum cutting tolerances
  • powered by AC servomotor with an especially low motor moment of inertia for highly dynamic cutting processes at high band speeds
  • fully-automatic setting to the material parameters including cutting gap adjustment for a minimal burr
  • Hydraulic knife clamping for speedy knife replacement



Drum shears

The drum shears continuously cut-through passing coil material, thereby cutting strips  into  blanks of identical length at high line speeds. Cutting tolerances are minimal and production output is high.

  • Strip materials such as steel, stainless steel, aluminium, copper and their alloys with (yield) strengths of up to 1,000 N/mm2
  • For strip widths in excess of 2,200 mm
  • Different version for band thicknesses from 0.1 to 4 mm.
  • Continuous cutting of strips for line speeds from 30 m/min to 300 m/min
  • Section lengths from 300 mm to over 14 m
  • Available for 90° cuts or as swivel shears for trapezoid, triangular, arc or profile cuts
  • Shears have their own PLC with interfaces to various bus systems (interface to other line components)
  • Vector-controlled drives to ensure minimum cutting tolerances
