Abstract
In a sandal, lateral parts are produced without a separate cementing process in a hollow mold in a single operation as a show sole is made by foaming. To this end the hollow mold has lateral pockets in which the strap parts are fixed by a holding frame reaching partially over the bottom end of each strap part before plastic is placed in the hollow mold and the mold is closed for foaming.
Claims1
A hollow mold for the manufacture of a sandal having a shoe sole and strapping fastened thereon comprising a cavity forming the shoe sole, lateral pockets for receiving and fixing the strapping on both sides of the cavity, and means for fixing the ends of the strapping in the pockets so that plastic foaming up in the hollow mold will not reach the back of the strapping, wherein the pockets terminate at a short distance from the bottom of the hollow mold and have a holding frame for the strapping which reaches slightly over the contour of the strapping.
