Apparatus and Methods for Producing Shrink-Wrap Packaging
摘要:
A vacuum table (18) includes an introduction section (102) in fluid communication with a vacuum chamber (120) and a compartment (139) dividable by an adjustment partition (156) into primary and secondary vacuum chambers (139a, 139b). Adjustment plates (130) having adjustment apertures (138) are positionable over apertures (128) of the conveying surface (100) of the vacuum table (18) generally perpendicular to the conveying direction. Film (20) extends from between the nip of pinch rollers (12, 13) to the conveying surface (100) and is tensioned therebetween to be cut in excess of 105 cuts per minute by a servo motor controlled rotary cutter (30) which stops after each cut. The shaft (32) of the rotary cutter (30) includes a bore (310) extending from the idle end to provide servo-control loop stability.
