Abstract

An improved tensioning method, for tensioning the tying medium of a package tying machine, results from mounting a novel tensioning device on the tying machine's rotatable twine arm. The tensioning device utilizes a funneling structure to gather the tying medium, whether twine or tape or other material, into a prescribed volume while tensioning the same, thereby allowing a relatively high uniform tension value to be maintained in the tying medium throughout the package tying cycle.
