SMA-SRW

Description

The slitter/rewinder is designed for the slitting and rewinding of narrow rolls of paper and abrasive cloth via pressure or scissor-cutting system. It is managed by an integrated PLC system, with a wide-angle touchscreen display that allows to control programming through numerous customised solutions. A specific interface provides automatic and real-time control of the electromagnetic brake and of the vector inverter motors (which serve as clutches) with extra-sensitive regulation. This machine is equipped with a set of decoilers and recoilers that have anodized aluminium expandable shafts whose diameter is Ø 76 mm or customisable, and sliding or tilting safety chucks. During the rewinding phase, the traction of the fibre and the balancing of the roll are consistently and automatically controlled. The cutting unit consists of either side-by-side blades or single repositionable knifeholders. This machine can be equipped with friction shafts. It also has a cross-cut unit that dissects the roll. The machine has a working width of 1100 to 2100 mm.
