Fastening strap, foam article including same and method for manufacturing the fastening strap

摘要

One aspect of the present invention provides a fastening strap for used in a foam article. The sideway-bendable fastening strap for a foam article includes a substantially flat hollow helical body made from a single hook strap and having a first outer surface, a second outer surface, and a plurality of hooks integrally formed on each of the first and second outer surfaces; wherein the hook strap is formed by plastic injection process and has a substrate and a plurality of hooks integrally formed on one face of the substrate, and wherein the hollow helical body is formed by sequentially and continually folding the hook strap from one end of the hook strap toward the other end of the hook strap along a number folding lines which are parallel with each other and at an angle θ with respect to a longitudinal axis of the hook strap with the face having the hooks formed thereon facing outward such that the hook strap is plastically and permanently deformed at the folding lines to form a hollow helical body having a width w.
