Abstract
A process for temporarily fastening the flaps of shoe uppers for a lasting step includes aligning pairs of opposed eyelets of the flaps, propelling one of a pair of substantially parallel legs of each of a plurality of generally U or H shaped fastening element through respective pairs of the aligned opposed eyelets and positioning the thus prepared upper on a last for a lasting operation. The substantially parallel legs of the fastening elements serve to maintain the flaps in connected relationship and are readily removed from the eyelets by severing of a bridge element which extends between and connects the legs.
Claims6
A process for the temporary fastening of the flaps of a shoe upper prior to lasting of the upper, comprising aligning pairs of opposed eyelets formed in said upper, propelling fastening elements including a pair of substantially parallel legs and a bridging element extending between and connecting said legs through said aligned eyelets such that one of said legs of each fastening element passes through both aligned eyelets following a path which is generally normal to the planes of said eyelets until it passes through the second of the aligned eyelets and then adopts a disposition generally parallel to said second eyelet, the legs of said fastening elements thereafter preventing separation of said flaps beyond a predetermined distance established by the length of the bridging elements.
