An apparatus for the production of reinforcement non-woven net fabric which is provided with selvage nipping devices for nipping selvages of a weft sheet constituted by loop end portions of reaches of weft thread on both sides of the weft sheet and advancing the weft sheet with the weft thread reaches laterally tensioned, an adhesive applying device for coating thermoplastic adhesive on the weft sheet being nipped by the selvage nipping devices except for the selvage portion of the weft sheet, a heating device for drying and melting the adhesive on the weft sheet, and a sheet pressing device for pressing and bonding to each other the weft sheet with melted adhesive thereon and a preheated warp sheet. During applying of the adhesive the weft thread reaches can be maintained exactly straight and in parallel and spaced relationship, and no adhesive is applied to most of the warp thread, other than at the intersection points with the weft sheet. Further, the sheet press device has a peripheral surface which is controlled so as to keep the temperature lower than softening point of the adhesive, whereby the composite of weft and warp sheets can be easily and rapidly released from the sheet pressing device.

Apparatus for the production of reinforcing non-woven fabrics for

The present invention provides a non-woven reinforcements for resinous composite. The reinforcements are constructed with warps consisting of non-twist yarns or soft twist yarns of multi-filament having a high strength and a high modulus on one or both sides of wefts of non-twist yarns of soft twist yarns containing adhesive agent, in which the warps and the wefts are bonded at intersections thereof. As the reinforcement of the present invention has no flexure different from a woven fabric, fiber's physical property such as a high strength, a high modulus and the like is reflected faultlessly on the composite using the reinforcement. In the reinforcement warp is not substantially restrained, so that matrix resin can be impregnated sufficiently into the reinforcement. Further, because the warps and wefts are bonded at intersections by adhesion, the reinforcement is much easier to be handled without deformation or falling off especially after cutting than the case of a woven fabric.
