Abstract
A vibrator assembly is for use on a strapping head for a strapping machine configured to position, tension and seal strapping material around a load. The strapping head includes a body, an anvil, and a welding motor having a rotating output shaft. The vibrator assembly includes an eccentric element operably mounted to the welding motor output shaft for rotation therewith. A bearing is disposed about the eccentric element, A housing is houses the eccentric element and bearing at least in part within the housing. The housing defines a cup-shaped well having a first axis length and a second axis length. The first axis length is longer than the second axis length. The first axis length is in a transverse direction, and the second axis length is in an oscillating direction. The bearing is restrained in the oscillating direction. A weld pad is operably connected to the housing by a link. As the motor output shaft rotates, the eccentric element is rotated and in turn rotates the bearing to impart oscillating motion to the weld pad in the oscillating direction. The bearing is restrained from moving in the transverse direction.
