ABSTRACT:
A strap feed assembly wraps a flexible strap around an item. A drive wheel is connected to a reversible drive motor for feeding and reversing the strap to wrap the strap around the item and to tension the strap once it is wrapped therearound. A controller operates the drive motor to control the speed, acceleration, direction of rotation, and tensioning of the strap. The velocity and acceleration of the drive motor are varied depending on the nearness of completion of the feeding and tensioning. Variable tension is achieved by monitoring the current drawn by the drive motor and comparing same to predetermined values to stop reversal and therefore tensioning.
