Abstract

A method for stabilizing and aligning interlocked male and female profiles of a plastic zipper strip during attachment of the strip to a polymeric film requires the use of profiles having stabilizers, perhaps taking the form of wedges. The stabilizers, disposed in pairs on each side of the interlocked male and female members of the profiles, mechanically cooperate with one another to maintain the profiles substantially parallel to one another and incapable of rocking about a longitudinal axis. The stabilizers on the male profile may be inboard, outboard or at the same distance from the interlocked male and female members as their respective stabilizers on the female profile. The facing surfaces of the stabilizers may be inclined so as to provide a wedging action with respect to one another.
