on the mating tape not shown regardless of the orientation of the latter a modified form of pile loop 17a is shown in fig2 d which is represented by stitch link no 3 2 2 2 2 1 2 2 formed by threads 16a lapping on every other adjacent needles over every other course the height of the pile loops 17 17a may be adjusted by the number of needles to be skipped in the weft wise direction and the number of courses to be skipped in the warp wise direction the foundation of the support tape 10 is formed by two needle stitches 14 of link no 0 2 2 0 as shown in fig2 b and laid in weft threads 15 of link no 0 0 4 4 as shown in fig3 the sinker loops 14a 14b of two needle stitches 14 are arranged to urge and hold the leg portions of pile loops 17 criss cross against the foundation web of the tape 10 while the laid in weft threads 15 fill up in between the sinker loops 14a 14b and the pile loops 17 thus anchoring the pile loops 17 stably in place against displacement or dislocation as better shown in fig3 the sinker loops 14a 14b of two needle stitches 14 are laced in a manner to bear against the foundation loops 19 that form the wales 18 and the weft threads 15 that are laid in densely between the foundation loops 19 and the sinker loops 14 14b are.
