Abstract

A tightening apparatus for strapping an object with a plastic band includes a holding mechanism with an eccentric shaft, a stationary gripper plate, and a moving gripper plate mounted on a shaft that moves within a slot on the frame of the device. The fact that the shaft moves within the slot allows the apparatus to function with the teeth of the moving gripper plate never touching the teeth of the stationary gripper plate in any position, thereby greatly increasing the useful life of the device. When a band is inserted into the device, only the rearmost rows of teeth on the moving gripper plate contact the band. The other teeth of the moving gripper plate are bought into contact with the band as the tightening force is applied. A return mechanism returns a windlass to an optimal loading position following each tightening operation.
