Abstract (en)
[origin: US6032440A] The invention is a machine for tying up or hooping packing units with an elongated strip of binding material, such as bondable plastic. During operation of the machine, the strip is drawn from a take-up device of a supply roller through a strip conveyor device and a strip guide, then is wound around the packing unit as a loop. The loop is tightened by means of a tensioning assembly comprising a tension roller and a pressing device which presses the strip against the tension roller, such that the loop is placed under tension. Once the packing unit is tightly secured, the strip is sealed by means of a sealing device. The present hoop-casing machine permits a high tension force to be exerted on the strip loop to be sealed. For this purpose, the tension roller comprises on its peripheral surface a high friction surface. At least one rejecter is provided for preventing excess wear on the high friction surface during the tensioning step. The rejecters can be moved between the strip and the friction surface of the tension roller.
