RK PSC 320 PVC Shrink Sleeve Cutting Machine
Cuts seamed shrink film to length on the print mark, sleeve after sleeve.
Seamed web in, stacked sleeves out
The RK PSC 320 takes the seamed sleeve web off the glueing machine and cuts it to length, sleeve by sleeve, on the print mark. Finished sleeves land on a motorised conveyor and come off the end in a neat stack, ready to be counted, boxed or fed straight to an applicator. It runs second in a shrink sleeve line, after the RK PSG 650.
Length accuracy comes from two things working together. A servo motor pulls the web a set distance for every stroke, and a Panasonic print mark scanner reads the register mark and corrects the pull before the blade comes down. The scanner pulls that drift back on every sleeve, so a long run does not end with a creeping cut line.
The unwind takes rolls to ø700 mm on a 3 inch multi-bladder air shaft, mounted on a cantilever so one operator can load a roll from the side. An imported ultrasonic edge scanner guides the web and a 0.5 HP AC motor handles paper pulling, with a mechanical brake holding unwind tension. A static eliminator sits on the web path, because PVC film picks up charge and charged sleeves cling to each other instead of stacking.
The cutting unit runs on a mechanical eccentric movement, so the stroke geometry holds its setting over long runs. A digital controller counts cut sets, sheet sets and total strokes, so an operator can set a batch and walk away from it.

Key Features
A servo motor sets the pull length for every stroke, so sleeve length repeats.
A Panasonic scanner reads the register mark and corrects the cut before the stroke.
One operator loads a full roll from the side without a crane.
Edge scanner keeps the web centred through the cutting station.
Stroke geometry holds its setting through long production runs.
Counts cut sets, sheet sets and total strokes so batches finish unattended.
Removes the charge that makes PVC sleeves cling instead of stacking.
0.5 HP geared motor on a VFD, so collection speed matches cutting speed.
