Abstract

A winder for a strapping machine that positions a strap material around a load and tensions the strap material around the load includes a rotating head portion having a stationary element and a pivotal element. The elements each define an outer surface around which the strap material is wound and a slot therebetween for receiving the strap material. The elements each include a gripping portion at about respective ends opposingly facing one another. The pivotal element pivots between an open position in which the gripping portions are spaced from one another and a closed position in which the gripping portions cooperate with one another to engage and secure the strap material. The winder includes a pivot assist assembly to urge the winder to the closed position. A strapping machine and a strapping head are also disclosed.

Description

technical field [0001] The present invention relates to strapping machines. More particularly, the present invention relates to an improved winder for a strapping machine. The strapping machine uses the tension of the strap to clamp the strap in this winder. Background technique [0002] Strapping machines are widely used to form a taut loop around a load with straps, such as plastic straps. A typical strapping machine includes a strap channel for guiding the strap around the load, a strapping head through which the leading end of the strap is fed, and a strap dispenser which dispenses the desired length of strap from a reel of strapping material. [0003] The strapping head has several functions. It advances the strap around the load along the slot until the leading end of the strap returns to the strapping head and pulls or rewinds the strap from the slot to tension the strap around the load. A strapping head typically includes means for securing a tensioning loop arou...
