ABSTRACT:
An improvement in a package closure crimping apparatus in which opposed crimping jaws are moved in crimping directions toward and away from one another to exert crimping forces for forming a sealed closure in a package constructed of thin film material having a given film thickness and placed between the crimping jaws, the sealed closures extending along a prescribed length between opposite package edges, includes a crimping jaw carrier for movement along the crimping directions, a crimping jaw carried by the crimping jaw carrier for movement with the crimping jaw carrier, the crimping jaw having a jaw length extending along the prescribed length, and a cushion of resilient material interposed between the crimping jaw and the crimping jaw carrier, along the prescribed length, for facilitating distribution of the crimping forces along the jaw length of the crimping jaw.
