Abstract
In a strapping machine, a device for applying various levels of gripping force to a leading end of a strap during various phases of a strapping cycle is disclosed. A cam having high pressure, reduced pressure, and released pressure surfaces cooperates with an end gripper to grip a strap firmly, loosely, or not at all, depending on the requirements.
