ABSTRACT:
A strapping head for a strapping machine includes a novel anvil arrangement having an offset connecting link for translating eccentric drive movement to linear oscillations for effecting strapping welds. The strapping head includes a stationary body, an anvil mounted to the body. A sealing member is disposed in a slot in the anvil. The sealing member oscillates in a longitudinal direction and is restrained from movement in a direction transverse to the longitudinal direction. The offset link operably connects the drive and the sealing member. The link has a first element adapted to receive an eccentric movement and a second element adapted to deliver a linear oscillating movement. The first and second elements are operably connected to one another by a connecting pin. The first and second element lie on different planes to permit ready removal of the sealing member from the anvil slot.
