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.
