Abstract
This invention provides a fastener strip in which fastening elements form a fastener layer on a front face of the fastener strip. Vertical walls are disposed along each of side edges of the fastener layer and each vertical wall comprises wall portions formed with an appropriate interval for controlling the degree of foam penetration during the molding process. The wall portions fix the fastener strip to an object during molding of the object and form an effective seal against fouling of the fastening elements.
Claims37
A fastener strip to be integrated with a surface of a foam-molded product for fixing a surface material, in which vertical walls are formed on both side edge portions of the strip along a length of a surface a flat substrate made of thermoplastic resin thereof, and a plurality of fastening elements are formed in an area surrounded by the vertical walls, wherein each of the vertical walls having at least one raw of a plurality of wall portions arranged in line along the length, and gaps allowing passage of the foam resin are formed between the wall portions adjacent to each other.
A fastener strip to be molded into an object material, comprising:
- (a) a substrate comprising first and second major surfaces, and first and second opposed side edges, and
- (b) a plurality of hook-like fastening elements upstanding from the first major surface of the substrate, and
- (c) a plurality of wall portions upstanding between the hook-like fastening elements on the first major surface of the substrate and the side edge of the substrate, for controlling a degree of foam intrusion from the side edge portion of the substrate during a molding process, wherein
- the fastener strip can be molded in the object material without the foam fouling the hook-like fastening.
A fastener strip to be molded into an object material, comprising:
- (a) a substrate comprising a first and second major surfaces and at least one edge, and
- (b) a plurality of hook-like fastening elements upstanding from the first major surface of the substrate, and
- (c) overlapping vertical walls upstanding from the first major surface of the substrate between the hook-like fastening elements and the edge of the substrate, for controlling a degree of penetration of foam intrusion from the side edge of the substrate during a molding process, wherein
- the fastener strip can be molded into the object material without the foam fouling the hook-like fastening elements.
