INVISIBLE SfJOOP STRINGERS EMPLOYING
ABRASIVE PREVENTING MEANS

2 Claims. (Cl. 24-2051)
This invention relates to separable fastener stringers,
The coupling end portions of each of the scoops in
clude, in alinement with the recesses '16, 16', laterally
projecting integral shelves or ?anges 17,17’ which project
beyond side edge portions of the scoops, as will clearly
appear from a consideration of FIGS. 1 ‘and 3 of the
drawing. 'For purposes of description, that part of the
stringer tapes between recessed portions of adjacent scoops
on each stringer can be de?ned as tape areas 18, as noted
in the area between the two scoops 11' in FIG. 1 of the
wherein scoops are applied to reversely folded edge por 10 drawing. The shelves or ?anges of adjacent scoops 11'
