Embodiment Construction

[0021] Referring now more specifically to the drawings in which like elements are similarly numbered, figure 1 Apparatus 10 for making a nonwoven web, member or article is shown. Apparatus 10 is part of a fusion bond forming machine that uses processes other than weaving to make flat or nonwoven webs, components or articles. Nonwoven webs, structures or articles typically consist of fibers or filaments bonded together. Generally, spunbonding involves the extrusion of molten polymer from a spinneret or spinneret, where the molten polymer is processed to form a curtain of strands. An example of such a device is set forth in US Patent Application No. 5,814,349. A large air flow is used to pneumatically stretch, elongate or attenuate the strands which are deposited on the forming fabric 12 after passing through the diffuser and presses are used to apply pressure to the deposit of filaments. As shown, by way of example, there are two presses, a downstream press 14 and an upstrea...

Abstract

In an apparatus for the production of a non-woven web, structure, or article using a spun-bonding process in combination with a forming fabric which is woven having flat CMD yarns, flat MD yarns or both with some or all of such yarns being conductive so as to dissipate static electricity.

Description

technical field [0001] The present invention relates to a fabric used in combination with a fusion bonding device for forming, conveying and bonding sheets into a nonwoven fabric. Background technique [0002] Currently in use is a device for producing spunbond webs, structures or articles from filaments or fibers, the monofilaments or fibers typically being made from thermoplastic resins. Such devices are disclosed in US Patent 5,814,349, filed September 29, 1998, the contents of which are incorporated herein by reference. Such apparatus typically includes a spinneret to produce a curtain of strands, and a process air blower for blowing process air onto the curtain of strands to cool the curtain of strands to form thermoplastic filament. The thermoplastic filaments are then entrained pneumatically by the process gas, typically for pneumatic stretching, and after passing through a diffuser, the thermoplastic filaments are then deposited on a continuously circulating screen...
