Abstract:
1. A method for sealing portions of a thermoplastic fastener strip, which method comprises the steps of: providing a thermoplastic fastener strip; vibrating a portion of the fastener strip so as to increase the malleability of said portion, as compared to the malleability of the fastener strip before vibrating; pressing a first matrix at a first location against the malleable portion to produce a first shape; transferring the malleable portion to a second location juxtaposed to the first location while the malleable portion is still malleable; pressing a second matrix at the second location against the malleable portion while the portion is still malleable to produce a second shape, thereby enhancing the first shape, and wherein an essentially airtight dam is formed; and cooling the malleable portion to transform the malleable portion.
