Features: (1) digital control with high accuracy operations. The micro computer with LCD display gives lots of fine features such as: Automatic unwind tension control, Automatic tension compensation on unwinder, automatic machine stop when there is a lack of material, the length is reached or material breaks. Memory capacity up to 50 sets of parameters. Ipack R&D friction rewinder allows for diameter detection, vector type motor, pneumatic lay-on roller. (2) ipack R&D friction type rewinding shaft handles various torque between shaft and sliding ring provides uniform rewinding tension. Rewinding speed difference Caused by material thickness variation can be compensated by the sliding motion that ensures consistent tension at all times. Mechanical speed:300m/min (max. ) Unwind width:1300,1600mm Unwind diameter:1000mm(max. ) Rewind width:50mm(min. ) Rewind diameter:600mm(max. )
