The most essential parameters

  • Strip widths up to 2,800 mm, dependent on material and customers demands
  • For line speeds > 1,800 m/min, dependent on material properties and customers demands
  • Edge-trimming of typical gauge ranges of: 0.08–0.8 mm, 0.1–1 mm, 0.3–4.0 mm, 0.5–6 mm, 1–8 mm, 2–10 mm, 4–15 mm

  • Centre cut shears
  • Automatic adjustment of width, cutting gap, and knive overlap
  • Regrinding of the knives on the circumference or on the flat surface
  • Permanent driven shear heads or non driven with free run clutch

Scrap baller

The scrap cut behind the shear, caused by the trimming process, is guided underneath or is sucked by a fan system and wound onto a scrap baller and into a scrap ball. A lifter transports the scrap ball to the top and drops it into a scrap container.

For the processing of carbon steel, silicon steel, stainless steel and non ferrous metals such as aluminium and alloys, lithographic, copper, brass and titanium.

The most essential parameters

  • Cut-off edge width from 3 mm up to 100 mm per side, dependent on material and customers demands
  • Scrap removal of typical gauge ranges of: 0.08–0.8 mm, 0.1–1 mm, 0.3–4.0 mm, 0.5–6 mm, 1–8 mm and 2–10 mm (only cutting)
  • For line speeds up to 500 m/min for scrap chopping and speeds > 1,800 m/min for scrap balling

Scrap chopper

The scrap chopper is provided to cut the edge strip produced during the edge-trimming process to short pieces for removal by transport conveyor.

The most essential parameters

  • Automatic adjustment to strip widths and cutting gap
  • Low-noise cutting of the scrap pieces
  • Two cutting edges per blade
  • Regrinding of the blades by means of a standard flat grinding machine – no regrinding shaft necessary
  • Separate driven hardened infeeding rolls for infeeding and tranport of thin cut-off edges
  • Long knife lifetime
  • No shimming after regrinding of the knives

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

The most essential parameters

  • 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 2,600 mm
  • Different version for strip thicknesses from 0.1 to 10 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

The GEORG heavy-duty roller leveler is optimally designed to match with the flexibility and quality of the finishing line. The GEORG quick-change cassettes widen the levelling range with various levelling roll diameters. Our handling systems like the levelling roll cleaning device and the cassette inspection table assist you in processing materials with sensitive surface qualities in steel or aluminium.

The GEORG roller leveller in detail.

Cropping shears have two functions: On the feeding side, they cut improperly dimensioned ends of bands. In the output area, they cut across bands according to a pre-set length of band.

The most essential parameters

  • 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 10 mm
  • Cutting strips to length in the start-stop mode
  • Section lengths can be preselected
  • Mechanic and hydraulic knife clamping
  • Mechanic and semi-automatic cutting gap adjustment

After the strips are cut into panels of various thicknesses, widths and lengths, these panels are stacked on pallets in a straight-edged manner without scratches.

Depending on the material, different stacking systems are used:

  • Magnetic stacking unit for ferrous magnetic materials
  • vacuum stacking unit for non-magnetic materials (for example aluminium or austenitic steels)
  • air floatation stacking unit for materials with insensitive surfaces
  • One or more stacking positions for “on-the-fly” change
  • Stacking of long sheet bars over several stacking positions
  • Single- or multiblanking operation
  • Strip widths of more than 2,400 mm
  • Band speed up to 120 m/min
  • Operating modes: Dropping panels in start-stop mode, in braked mode or in continuous operation
  • CNC-movable and swivelling stops with automatic adjustment to different panel sizes
  • Stacking by stacking masks is possible
  • Highly dynamic adjustment drives via servomotor for rapid program change
  • Controlled servo drives for magnetic and vacuum belts
