Abstract: An automatic binding apparatus produces a loop of tape and tightens the tape around an object that is inserted through the loop of tape. The apparatus has a bed-plate and a guide member which is swivelable into position on and off the bed-plate. Initially, the tape is guided through the guide member to form a small loop of tape. Thereafter the guide member is retracted and the loop of tape is enlarged by feeding more tape to the loop to accommodate large objects. Insertion of the object through the loop actuates a work detection switch and detection of the object produces an output signal which triggers a process whereby the tape is tightly bound around the object, is cut from the tape supply, and the ends of the tape are overlapped and pressure welded to one another. Removal of the bound object changes the state of the work detection switch and results in the repositioning of the guide member over the bed-plate and in the formation of a fresh loop of tape for a next object to be bound.
