ABSTRACT:
An apparatus for securing a tensioned plastic band which has a rotatable tensioning wheel and a friction shoe which is located adjacent a band path for two mutually overlapping end portions of a band located around an article is disclosed. The shoe is reciprocatable transversely to the band path, and displaceable into and out of contact with the upper band end portion. A single drive means is permanently coupled to the shoe for reciprocation, and drives the tensioning wheel via a torque-sensitive coupling. In operation, the shoe is initially out of contact with the band, and the wheel is driven so as to tension the band until a predetermined tension is reached. Thereupon the coupling uncouples, and actuates means which urge the shoe against the band. This causes relative motion of the band ends, resulting in their being frictionally welded together. The uncoupling also actuates a cutting member for the band. Thus the sequence of tensioning, welding and cutting is performed automatically.
