"Angel Stoilov-96" JSC Longitudinal cutting is a mechanical process of cutting metal, as a result of which a certain number of strips of smaller width are obtained from a roll. The strips are usually an intermediate product, mainly used in large-scale and mass production for manufacture of pipes, cold-bent profiles, metal structures, air ducts, packaging tapes, chimneys, etc. Cold and hot rolled steels, galvanized and with other coatings, paper, copper, aluminum, and their alloys can be cut.
The essence of the process is the passage of the processed sheet between two rotating shafts, on which high-strength steel disc knives for cutting and rubber rollers for pulling the sheet are mounted, with subsequent separation and winding of the strips on separate rolls. The number of strips and their width is determined by the number of cutting discs and their location on the shafts.
The cutting is performed with precise, high-speed, automated production lines that unwind the coil, guide the sheet to move along the longitudinal axis of the line, and synchronize the speeds of unwinding and slitting the sheet and winding the strips and waste into rolls.

– Inner diameter of a roll: 485-520 mm
– Maximum kilograms per roll: 10,000 kg
– Inner diameter of tape roll: 508 mm
– Outer diameter of tape roll: up to 1,500 mm
– Accuracy of the tape width: 0.2 mm
– Maximum cutting speed: 80 m/min.
