Abstract
A pouch perforator for a form, fill and seal packaging machine of the type which forms pouches from continuous film includes a cutting element and a support element. The cutting element is rotatively mounted on the packaging machine as is the support element with the cutting element located on one side of the film and the support element located on the opposite side of the film. The cutting element includes a plurality of axially extending knife edges located in a circumferentially spaced array. The knife edges rotate in response to rotation of the cutting element. The support element includes a circumferentially extending support surface which rotates in response to rotation of the surface element. The knife edges in response to rotation of the cutting element compress film against the support surface to perforate the film.
