Title:
CONTINUOUSLY CONNECTED FASTENER STOCK AND METHOD OF MANUFACTURING THE SAME
Document Type and Number:
WIPO Patent Application WO2003006324
Kind Code:
A9
Abstract:
Continuously connected fastener stock and a method of making same. In one embodiment, the method involves providing a rotating molding wheel, the wheel being provided with a peripheral impression comprising a pair of peripherally-extending side members interconnected by a plurality of cross-links. Molten plastic is extruded into the peripheral impression of the wheel, with a layer of controlled film overlying the peripheral impression. The molten plastic is then allowed to solidify. A knife in substantially elliptical contact with the peripheral impression is then used to skive excess plastic from the rotating molding wheel. The knife is provided with a pair of cut-out portions along its bottom edge, each cut-out portion aligned with one of the peripherally-extending side members so as to augment the transverse cross-sectional size thereof. The continuously connected fastener stock thus formed is then removed from the rotating molding wheel.
