Method for adapting separable fasteners for attachment to other objects
First Claim
1. A process wherein a strip of fastener material is formed into the surface of an article during molding of liquid foam-forming material in a mold to form the article, wherein the fastener material comprises a backing strip having an outer surface adapted to mate with the foam material during molding and a fastener strip having an outer surface comprising one-half of a touch fastening system, wherein the backing strip and the fastener strip are attached to one another with their respective inner surfaces in face-to-face relationship and with their outer surfaces facing outward, and wherein the fastener strip fits within a groove in the mold and the backing strip overlaps the groove, wherein in order to prevent the liquid foam-forming material from entering the groove during the molding and contaminating the outer surface of the fastener strip said process includes the steps of:
- (a) forming the backing strip so that it is wider than the fastener strip;
(b) disposing the fastener strip on the backing strip so as to have side strips on the inner surface of the backing strip exposed on either side of outer edges of the fastener strip;
(c) disposing a pair of strips of polyethylene film along respective ones of the exposed side strips with the film strips attached to the side strips along lines adjacent the outer edges of the fastener strip and extending between the outer edges of the fastener strip and outer edges of the backing strip, portions of the film strips adjacent the outer edges of the backing strip remaining unattached so as to form gasket strips of the film along the side strips on either side of the fastener strip adjacent the outer edges of the backing strip; and
(d) positioning the fastener material, prior to introducing the foam-forming liquid into the mold, in the mold with the gasket strips forming a pair of gaskets between the backing strip and the mold adjacent the groove where the backing strip overlaps the mold.

Abstract
An improvement for a process wherein a strip of fastener material is formed into the surface of urethane foam or the like during molding in a mold. The fastener material includes a backing strip having an outer surface adapted to mate with the foam material during molding and a fastener strip having an outer surface comprising one-half of a fastening system such as hook and loop fastening material. The backing strip and the fastener strip are attached to one another with their respective inner surfaces in face-to-face relationship with their outer surfaces facing outward. The fastener material fits within a longitudinal groove in the mold and the backing material overlaps the groove.

1. A process wherein a strip of fastener material is formed into the surface of an article during molding of liquid foam-forming material in a mold to form the article, wherein the fastener material comprises a backing strip having an outer surface adapted to mate with the foam material during molding and a fastener strip having an outer surface comprising one-half of a touch fastening system, wherein the backing strip and the fastener strip are attached to one another with their respective inner surfaces in face-to-face relationship and with their outer surfaces facing outward, and wherein the fastener strip fits within a groove in the mold and the backing strip overlaps the groove, wherein in order to prevent the liquid foam-forming material from entering the groove during the molding and contaminating the outer surface of the fastener strip said process includes the steps of:
-
(a) forming the backing strip so that it is wider than the fastener strip; (b) disposing the fastener strip on the backing strip so as to have side strips on the inner surface of the backing strip exposed on either side of outer edges of the fastener strip; (c) disposing a pair of strips of polyethylene film along respective ones of the exposed side strips with the film strips attached to the side strips along lines adjacent the outer edges of the fastener strip and extending between the outer edges of the fastener strip and outer edges of the backing strip, portions of the film strips adjacent the outer edges of the backing strip remaining unattached so as to form gasket strips of the film along the side strips on either side of the fastener strip adjacent the outer edges of the backing strip; and (d) positioning the fastener material, prior to introducing the foam-forming liquid into the mold, in the mold with the gasket strips forming a pair of gaskets between the backing strip and the mold adjacent the groove where the backing strip overlaps the mold. - View Dependent Claims (2, 3, 4)

5. A process wherein a strip of fastener material is formed into the surface of an article during molding of liquid foam-forming material in a mold so as to form the article, wherein the fastener material comprises a backing strip having an outer surface adapted to mate with the foam material during molding and a fastener strip having an outer surface comprising one-half of a touch fastening system, wherein the backing strip and the fastener strip are attached to one another with their respective inner surfaces in face-to-face relationship and with the outer surfaces facing outward,
and wherein the fastener strip fits within a groove in the mold and the backing strip overlaps the groove, the process of preventing the liquid foam-forming material from entering the groove during the molding and contaminating the outer surface of the fastener strip comprising the steps of: -
(a) forming the backing strip to be wider than the fastener strip; (b) disposing the fastener strip on the backing strip so as to have side strips on the inner surface of the backing strip exposed on either side of outer edges of the fastener strip; (c) disposing a strip of polyethylene film over the fastener strip and along the exposed side strips with the polyethylene film strip attached to the side strips along lines adjacent the outer edges of the fastener strip and extending between outer edges of the backing strip, portions of the film strip adjacent the outer edges of the backing strip remaining unattached so as to form gasket strips of the polyethylene film along the side strips on either side of the fastener strip adjacent the outer edges of the backing strip; and (d) positionng the strip of fastener material, prior to introducing the foam-forming liquid into the mold, in the mold with the gasket strips forming a pair of gaskets between the backing strip and the mold adjacent the groove where the backing strip overlaps the mold. - View Dependent Claims (6, 7)

8. The method of improving a strip of fastener material adapted for forming into the surface of an article during molding of liquid foam-forming material in a mold to form the article, the mold containing a groove in the inner sidewalls thereof for receiving the strip of fastener material during molding to prevent foam-forming liquid from entering the groove during the molding and fouling the fastener material'"'"'s interconnecting surface comprising the steps of:
-
(a) forming the strip of fastener material as a backing strip having a first outer surface on one side thereof adapted to mate with the foam during molding and a second outer surface on the other side thereof comprising one half of a touch fastening system, the backing strip being wider than the second outer surface and the second outer surface being disposed to provide exposed side strips on either side of the second outer surface, the second outer surface being adapted to fit within the groove with the backing strip overlapping the groove; (b) disposing a pair of strips of polyethylene film along respective ones of the exposed side strips of the backing strip one either side of the second outer surface, said strips of film extending into the mold groove adjacent to side walls of the groove; and (c) attaching the polyethylene film strips to the side strips along lines adjacent the outer edges of the second outer surface, portion of the film strips adjacent the outer edges of the side strips remaining unattached so as to form gasket strips along either side of the second outer surface for contacting the mold to prevent entry of the foam-forming liquid into the groove whereby when the strip of fastener material is positioned in the mold, the gasket strips form a pair of gaskets between the backing strip and the mold along the area adjacent the groove where the backing strip overlaps the mold. - View Dependent Claims (9, 10)
