Abstract:
1. Method comprising: supplying a continuous web of film having a leading edge and first and second, spaced, longitudinal edges; moving the web of film through a first portion of a path, with the web of film being under tension in the first portion of the path; substantially cutting the web of film in the first portion between the first and second longitudinal edges to form a single sheet of film having a trailing edge spaced from the leading edge and creating a new leading edge on the web of film, with the trailing edge and new leading edge being connected together by a plurality of tie strips to maintain tension of the web of film in the first portion of the path after cutting; conveying the substantially cut web of film on a vacuum table; and breaking the tie strips between the single sheet of film and the new leading edge on the vacuum table by pushing on the web of film at the trailing edge faster than the substantially cut web of film being conveyed on the vacuum table and placing tensional forces on the tie strips which exceed tensional strength of the tie strips.
