ABSTRACT:
A flexible transverse-L cross-section support structure is capable of being mounted around curved edges of, for example, window frames, bed-head frames and table tops. The structure is specially suitable to receive one component of a flexible two component loop and hook fastening system which it is required will remain in a flat plane while the other arm of the support is bent in a curved plane. The first arm which carries the tape on its outer face is provided on its inner face, preferably about midway along its length, with a short relatively thick third arm extending parallel to the second arm to form a channel between them. It is now possible to bend a support so that the second surface is curved without unacceptable bending or buckling of the first arm and the supported tape out of the original flat plane.
