BINDING STRIP FOR PARTS OF BOOTS AND SHQES Filed July 31. 1950 Patented Oct 18, 1932 UNITED STATES PATENT? OFFICE PERCY E. STEVENS, LYNN, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MACHIN- ERY CORPORATION, OF PATERSON, NEW JERSEY,
A CORPORATION OI NEW JERSEY BINDING STRIP FOR PARTS OF BOOTS AND SHOES Application filed July 31, 1930, Serial No. 472,117, and in France September 10, 1929p is customary to finish certain edges of parts of the ppers by the use of a binding strip having a coating of adhesive substance on one side thereof over which extends a protective strip of fabric. The band of adhesive substance and the protective strip are somewhat narrower than the binding strip so as to "parentprotective leave exposed a marginal portion of the binding strip. A coil of this composite strip 1s mounted upon a reel associated with a sewing machine and a proper length is stitched to the display side of a shoe part in such manner that the edge of the binding strip along the uncoated marginal portion thereof and an ed e of stitches which attach the strip to the part being located close to said registering edges. The shoe part, with the composite strip thus attached, then goes, to the folding machine operator who tears off the protective strip so as to expose the band of adhesive substance and then folds the free portion of the binding strip about the attached portion and about the edge of the shoe part and presses the coated portion of the strip down upon that side of the shoe part which is hidden in the finished shoe.
In order to permit inspection of the adhesive coating while the protective strip is still in place as well as to ensure that no considerable amount of the adhesive coating shall be removed from the binding strip whenthe protective strip is torn off, there is provided, according tothe present invention, a transstrip having a smooth glassy surface. With such avconstruction the sewing machine operator may readily detect and discard portions of the binding strip upon which the coating of adhesive substance may be discontinuous or markedly insuificient; and the folding machine operator may tear oif the protective strip without danger of the shoe part are in register, the row of the adhesive substance.
Referring now to the accompanying drawmg, V
The figure is a perspective view of a portion of a composite strip in which the present invention is embodied.
The bindin strip, which may be of any suitable flexib e material and is commonly of silk, is indicated at 1. v The coating of adhesive substance, indicated at 3, is somewhat narrower than. the binding strip so as to leave uncoated anextent of the marginal portion of the binding strip. The protective strip 5, herein shown as partly torn off so as to expose a portion ofthe adhesive coating 3, normallycovers the coating completely, and is made of a transparent material having a smooth, glassy. surface. As examples of suit-- able substances form commonly called cellophane, pyroxylin, cellulose acetate, and other similar smooth, glassy, transparent materials which will readily occur asbeing more or less their equivalents for the purpose in view. The protective strip is herein illustrated as a film of cellophane.
In use a 0011 of this composite strip is mounted upon a reel which is associated with of a shoe part WlthB-Il edge of the shoe part in register with the edge of the binding strip and sews the two articles together by a row of stitches which is located close to the edge 7. With a composite strip made in accordance with the present invention, the sewing machine operator may inspect the adhesive coating through the transparent protective strip and thereby avoid sewing to a shoepart any portions of the binding strip on which the coating may be discontinuous or insufficient.
After the "sewing operation has been completed, the piece of work, as has been explained, goes to the folding machine operator who tears off-the protective strip and folds the binding strip about the edge of the shoe part. Due 'to the smooth hard glassy. surface of the protective strip, the adhesive I may mention, viscose in theof removing with it any considerable amount coating parts readily from the protective v strip and remains intact upon the binding strip. p Although the invention has been set forth as embodied in a particular composite strip, it should be understood that the invention is not limited in the scope of its application to the particular strip which has been shown and described. i Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent of the United States is:
A binding strip adapted to be stitched along one edge thereof to a shoe part and to have its unattached portion folded about the edge of the shoe part,'a coating of adhesive substance spaced from the edge which is to be stitched to the shoe part, and a transparent protective strip having a glassy surface overlying the coating whereby the adhesive substance may be inspected at any time, and remains onthe binding strip when the protective strip is torn ofl preparatory to the folding operation. In testimony whereof I have signed my name to this specification.
