Abstract
A fastening strip for touch fasteners is provided which includes a corrugated portion as well as fastening elements. The corrugated portion allows the strip to be bent in a plane perpendicular as well as parallel with the longitudinal axis of the strip such that it may be applied to curved surfaces and remain substantially flat. Fastening elements such as hooks, loops, mushroom-shaped, bulbous and double hooks may be included on both sides of the strip and on the walls of the channels that form the corrugations as well as between the corrugations. The corrugated fastening strips may be useful for automotive seating and diaper applications. Processes for forming the corrugated fastening strip area also disclosed.
Claims17
A touch fastening strip comprising:
- a corrugated strip defining an undulating surface and forming a plurality of channels and a base portion between adjacent channels, the corrugated strip defining a plane, the corrugated strip constructed and arranged to be bendable within the plane and out of the plane, and such that when the corrugated strip bends within the plane, the corrugated strip remains in the plane;
- fastening elements formed on and projecting from at least portions of a top of the undulating surface that define a fastening location;
- and
- a protective material configured to prevent contamination of the fastening elements during a molding process, wherein the corrugated strip is embedded in an object comprising foam.
