Abstract
397,283. Moulding boots and shoes ; extrusion-machines. GOODRICH CO., B. F., 37, West 60th Street, New York, U.S.A. -(Assignees of MacDonald, F. J. ; 1862, Beacon Street, Brookline, Massachusetts, U.S.A.) July 5, 1932, No. 18971. Convention date, Dec. 31, 1931. [Class 87 (ii).] Canvas and like fabric-topped boots and shoes are reinforced by moulding plastic material in adhesive engagement with the sheet material over definite portions of the upper and the whole shoe is assembled without stitching. A mould 44, Fig. 22, provided with deeper recesses corresponding to the reinforced portions, is pushed by a ram 50, Fig. 18, under an extrusion machine 48 to receive a sheet of rubber which is so thin at the margins of the reinforcement that the surrounding portions can be peeled off, leaving the reinforcements in the deeper recesses. A shaped sheet of fabric, which may comprise two superposed sheets connected by a rubber cement, is placed over the reinforcements in the mould and partly vulcanized while under pressure in a hydraulic press. An upper is produced thus, having a thickened margin all round the edges and additional thickened portions 33, 35, 36, 37, Figs. 1 and 2. A combined tongue and toepiece, as shown in Fig. 6, is formed by a similar operation. The upper then is eyeleted and assembled round a last together with the tongue and toe-piece and an insole. The margins 37a, Fig. 2, and 38a, Fig. 6, are bent under the last and cemented to the bottom of the insoles. The outsole is secured temporarily by cement to the insole and the whole vulcanized. A toereinforcing strip 42 may be included if necessary. The extrusion-machine has a laterally-adjustable slide at the mouthpiece, positioned by a screw to regulate the width of the outlet.
