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.

Abstract: A strapping head for a strapping machine of the type having a feed assembly and a chute that is configured to position, tension and seal strapping material around a load, includes a body and an anvil mounted to and movable relative to the body. A sealing member is disposed in the anvil for oscillating movement. A drive is operably connected to the sealing member and movable relative to the body to provide oscillating movement to the sealing member. First and second courses of strapping material overlie one another adjacent the sealing member, and oscillation of the sealing member effects a seal of the first and second courses of strapping material to one another.
