1600mm Wide Slitter & Rewinder With Auto Cut &Transfer For Continuous Operation

Independent Machine Company has developed a new 1600mm wide slitter with Pope-type Minimum Gap Surface assist Rewind and auto cut & transfer for light gauge non-woven materials.
Separate 2-position driven unwinds with closed loop tension control accommodate 2 meter [78"] diameter supply rolls and are positioned before the main process which is the speed reference of the entire system. A 36” diameter drum roll follows the main texturing process speed reference to 250 MPM and pulls the material through a ancer/accumulator that provides closed loop tension feedback and material storage to maintain speed during the auto cut & transfer.
The material is slit just before contact with the drum roll at the adjustable driven pneumatic shear assembly. The slit strands are wound to 2.5 meter [98”] diameter on individual cores all secured on a common air shaft. The rewind provides minimum gap winding and is driven by an AC follower drive to provide programmable taper winding throughout the entire rewind cycle. Roll density and rewind tension is controlled by continuous drive speed ratio changes during winding.
An automatic core shaft feeder loading system is located over the top of the drum roll. The shaft feeder has pneumatic clamps which grasp the shaft from the magazine by the journals and pneumatically lowers the shaft into the transfer arm assembly.
The cut-off knife on the lift roll assembly fires and severs the webs from the winding rolls and attaches to the preglued empty cores. The rolls wind to the predetermined length or maximum diameter programmed diameter. The multi drive AC vector system is controlled through an Allen–Bradley PLC with PanelView Touchscreen including recipe storage.
