Title: Improvements relating to rib stripping for use in the manufacture of footwear
IPC: A43B23/00
Filed: 1957-09-27
Abstract: 890,211. Ribbing for insoles. PRIME MANUFACTURING CO. Dec. 22, 1958 [Sept. 27, 1957], No. 30374/57. Drawings to Specification. Class 17(2) Rib stripping, comprising a rib portion and at least one attachment flange which is coated on one face with adhesive, is coiled with the adhesive flange surface or surfaces facing outwardly from the axis of the coil. The invention is shown applied to stripping comprising a core secured to a tape, as in Specifications 712,381 and 890,209. The uncoated surfaces of the tape may be sized or otherwise treated to avoid adhesion between neighbouring convolutions of the stripping. It is desirable to provide a protective packing layer, e.g. gauze, to protect the adhesive of the outer convolutions, particularly with two flange stripping.
