turns formed by a series of tapes 14 one of three sides has a sub strip 33 attached so that it is possible to complete a closed loop in fig5 c there is a seventh preferred embodiment 38 which is similar to fig2 except that an additional smaller tape strut 10 as shown in fig2 is added at inside so that the stiffness of tape strut 38 can be adjusted the two different sizes of tape struts 10 are combined together by rivet 35 all of the preferred embodiments described above may have multiple layers of more than one in cross section or multiple turns of overlap of more than one in cross section or required gaps or deformation or pre deformation of the shape in cross section to allow the entire tape strut to bend varying width in tape or in zipper proper attaching method to allow the zipper to slide freely to open or close and side edges of tape round off in fig6 there is a tape assembly 40 having a tape 14 and a casing 42 of course it may be a combination of tapes and zippers and the casing with the tapes and zippers rolled in coil or coils or in separated coils the casing consists of a lower half 44 a roller 46 an upper half 48 and a plurality of screws 50 the lower half 44 has a disk 53 with a vertical wall 54 on.
