ANTI-ROTATION SYSTEM FOR STRAP DISPENSER OUTER FLANGE

摘要

An anti-rotation system that prevents undesired rotation of an outer flange of a strap dispenser includes an anti-rotation element mounted to a shaft of the dispenser and the outer flange mounted to the anti-rotation element. The anti-rotation element and the outer flange have complementary mating surfaces such that when the shaft, on which the coil rotates, ceases rotation, the anti-rotation element, engaged with the outer flange, ceases rotation of the outer flange; thus, inertia of the coil cannot force the outer flange to rotate undesireably. A locking element abuts the outer flange to secure the flange to the anti-rotation element and a pin extends out from the shaft and inserts into a helical track in the locking element so that the pin rides in the helical track. The anti-rotation element also includes a through-bore for a fastener to secure the anti-rotation element to the shaft.
