Abstract
A separable fastener is disclosed which has the form of a tape having a plurality of laterally adjacent uniformly corrugated strips. Adjoining strips are staggered relative to one another so that the ridges of one strip are laterally aligned with the depressions or spaces between the ridges of adjoining strips, with the adjoining strips being joined together at their cross-over points. A second tape of identical construction can be joined to the first tape by merely pressing the two tapes together in a face-to-face relationship. There is also disclosed apparatus and a method for manufacturing the separable fastener which includes means for passing a strip of thermoplastic material through mutually engaging rolling dies which create the corrugations.
