CWSY is a widely used rewinder with triangle folding device at maximum line speed 125 meter/min to convert single sheet CPP, OPP, BOPP, HDPE and LDPE film rolls to double layers folded film rolls with one side open to produce side sealed bags with or without flap.

After folding, it is strongly recommended to leave the folded rolls idle for few days before using them or else immediate use of the newly folded rolls will have their edges pop out after sealing and cutting as the edges are not stable yet, especially for side sealed bags.

• Suitable for HDPE, LDPE, PP film folding.
• Air cylinders for up and down of unwinding stand.
• Dancing rollers with automatic tension control by AC motor with inverter for stable folded edge and perfect rewinding.
• German made E.P.C (Edge Position Control) to make the rewinded roll’s edge stable.
• Machine auto stops when film is broken or finished.
• Triangle folding device.
• Gusset inserting device at close side of folded film.
• Digital meter counter with preset and controlled by meter counting roller device.
• Dancing rollers at rewinder for continuous stable tension of film by servo motor.
• Air cylinders for up and down of lay-on aluminum roller at rewinder.
• Rewinder uses servo motor for fast stable speed and high quality rewinding.
• Air cylinder for up and down of rewinder’s arm to unload finished rewinded rolls.
• Air shafts for unwinder and rewinder units make change of rolls an easy task.
