Abstract
Abstract An apparatus is disclosed for applying bundle ties to bundles, the bundle ties being of the type comprising an elongated thin strip of plastic material having an opening in its trailing end so that the leading end of the tie can be inserted through the opening and the tie drawn up into snugly embracing relationship with the bundle. The apparatus comprises a means for feeding the bundle ties, leading end first, along a path extending around the bundle and through the opening in the trailing end of the tie. After the leading end is threaded through the opening, the end of the tie is grasped and pulled away from the bundle while the trailing end is pressed towards and against the bundle. A cutoff device, which is responsive to the development in a predetermined tension in the tie, is then operated to cut the excess portion of the strap which extends beyond the trailing end of the tie.
