Buffer holding drum for packing strap feed to packing machine facilitates smooth start-up and stopping at high reel speeds

摘要

A supply of packing strap (4) is fed (1) at high speed from a reel to a parcel strapping machine via an intermediate buffer drum (5). The drum has an inlet (6) for the strap to a helical holding channel (7) whose radial extension (r) is greater than the strap width extension (a). The holding channel feeds to an outlet (8) and strap draw-down drive (9).
