Slitting lines

Our slitting lines are designed to ensure the highest standards of quality and productivity while processing different materials – such as stainless steel, carbon steel (hot rolled and cold rolled), pre-painted steel and galvanized, aluminium, copper and brass – from the lowest thickness (0,3 mm) up to the highest ones (16 – 20 mm). Besides the cut, special attention is also dedicated to the strips tensioning activity, in order to assure the highest quality on the processed material surface and perfect coil rewinding.

COMPACT SLITTING LINE

The compact slitting line is featuring no more than 13 m distance between decoiler axis and recoiler axis.
This special kind of line is required by customers that need to solve logistic problems of room without affecting the production.

DOUBLE LOOP SLITTING LINE

Double loop slitting line is designed to have the first loop pit before the cut, under the circular blades shear, and the second pit after the cut.
This line process the material, especially thin material, avoiding axis deviation on strip.

  • Automatic change of cutting equipment
  • Braking by coil tensioning, countercurrent or by dragging
  • Fractioning of the head and tail of the coil
  • Application of plastic film
  • Application of paper
  • Paper winding
  • Storage of coils
  • Slitting & automatic change of slitting tooling set-up
  • Scrap balling & scrap cutting of scrap edges
  • Tensioning of slit strands: the tension carriage

DESIGNED TO OPTIMISE QUALITY AND PRODUCTIVITY, IN FULL COMPLIANCE WITH OPERATOR SAFETY REGULATIONS, ENSURING THE QUALITY OF WORK AND WITH PARTICULAR ATTENTION TO THE SIMPLIFICATION OF MAINTENANCE ACTIVITIES.
