Is a high speed shear machine (up to 300 cuts/min.) with a design for cutting the strip in formats at programmed lengths without stopping the processing strip.

The design is a double driven eccentric shear one of them with downwards displacement and opposite side acting upwards direction across the strip.

The motion of both shears is synchronised and fitted with reaction arms sliding on roller guides. The main frame of the shear is fabricated in carbon steel and stress relieved and fixed to foundations by anchor bolts and nuts.

  • Transmission tower stands for shafts support.
  • Driven by kinematic chain with back - less type of gear.
  • Eccentric shafts supported on bearings.
  • Low inertia knives - holder fitted on bearings.
  • Adjustment of cutting gap tolerance with gap control screen.
  • Pulses generator fitted in measuring wheel.
  • Tilting table fitted on bottom knives - holder as support for short length formats.
  • Lubrication for close oil circuit and flow control system.
