ABSTRACT:
An arrangement for molding a flat insole (412) and adhesively attaching the molded insole to the bottom of a last (414) comprising an upper mold (62) and a lower mold (14) having complementary molding surfaces that are initially spaced from each other so that the flat insole is transported between the molding surfaces and are then closed upon the insole to mold the flat insole to the shape of the molding surfaces. The upper mold is then raised while the molded insole is retained on the upper mold molding surface after which the insole is released from the upper mold molding surface and descends onto the bottom of the last. The molded insole is then pressed onto the last bottom by an applicator (378) and is attached to the last bottom by an adhesive patch (421) on the last bottom that was previously applied to the last bottom by the applicator.
