Patent ID: 7934305

Claim:
A process for manufacturing a fluidtight slide fastener comprising the steps of: providing a plurality of strips of a textile material covered with a fluid-barrier material layer at least on both opposite faces of the textile material strips, equipping each coated strip with a plurality of sets of aligned teeth along a longitudinal edge thereof, heat cutting each coated strip transversally at short cutting edges between consecutive sets of aligned teeth to obtain a plurality of tapes of desired dimensions, wherein each tape is equipped with a set of aligned teeth along a longitudinal edge thereof, and wherein the textile material is heat sealed in a fluidtight way at the short cutting edges of the tapes by a portion of said fluid-barrier material layers on the opposite faces of said strip due to the heat cutting step, and coupling said plurality of tapes in pairs and equipping each pair of tapes with a closing stop, an opening stop and a slider slidable between said closing and opening stops.
