Embodiment Construction

[0020] See attached picture now. In the drawings, the same reference numerals represent the same components or steps. A preferred embodiment of the invention is shown in FIG. 1 . Figure 1 illustrates the general structure of an apparatus used to manufacture one embodiment of the present invention. In a storage container 12, there is polymeric material, such as polyvinylchloride (PVC) or polypropylene, in a molten state. A first material dispenser 15 containing a sheet material 16 is located adjacent to a spinning roll 14 . A plurality of material dispensers 17 , each containing a filamentary material 18 , are also located near the spinning roll 14 . In use, the sheet material 16 and the filamentary material 18 are fed into the spinning roll 14 . When the molten material 19 is extruded from the extrusion nozzle 13, its shape is determined by the spinning roller 14, but it does not harden immediately. During hardening, the material 11 remains viscous. As the molten materia...

Abstract

A method of manufacturing an extruded sheet material, wherein a polymeric material (11, 21, 31, 41) is formed into a sheet and several materials (16, 26, 36, 46) are The extruded material hardens before being incorporated into it. The sheet material (16, 26, 36, 46) thus obtained combines sheet, filament or granular materials on both sides of the finished product, thereby making the finished product highly flexible.

Description

[0001] This application claims priority based on US Provisional Patent Application No. 60 / 275,485, filed March 14, 2001, entitled "Female Engaging Surface Fastener Having Backing and Method of Making Same." technical field [0002] The invention relates to the field of surface fasteners and their manufacture. In particular, the present invention relates to a surface fastener made of polymeric resin having a female engaging member bonded thereto, the surface fastener additionally comprising a second engaging member bonded thereto. Background technique [0003] Buckles by surface engagement are known in the art, usually a hook and loop construction. Such buckles are largely manufactured according to two known methods. A more traditional approach is to weave hook and loop fasteners. Loop engaging elements are typically woven from multifilaments to form a patterned fabric with protrusions that form the loops. These hooks can the...
