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.

Abstract: A new method and apparatus for the installation of sector-shaped curtains on correspondingly shaped windows requires the provision of a piece of curtain material of suitable length and width; sheer tape is attached to the top edge and the piece is gathered using the tape to the length of the curved circumferential portion of the window. One part of a two part hook-and-loop fastening is attached to the curved portion of the window while the other is sewn to the gathered curtain top edge and the curtain is then attached using thus fastening. A securing member having two protruding side-by-side impaling spikes is attached to the middle of the straight circumferential window casing portion and the curtain is then impaled while under tension on the two spikes, one half on each. The curtain is usually completed by impaling a decorative finial on a third spike disposed between the two on which the curtain is impaled so as to cover the bunched curtain material at this point.
