Abstract: A method of positioning two workpiece portions for stitching together along a desired stitching path.A pallet is provided for positioning workpiece components (e.g. a vamp V and quarter portions RQ, LQ of a shoe upper) in position for stitching the portions together, where, when the various components are in a flat condition, the regions (corresponding to the desired stitching paths) of the various components are not in overlapping relationship; that is to say, the pallet enables distortion of at least one of the components in order to bring the regions of the various components into such overlapping relationship. This is achieved by locating e.g. the quarter portions RQ, LQ in a flat condition in relation to a slot (14) of the pallet, which slot corresponds with the desired stitching path, and thereafter positioning the other component, e.g.

Abstract: A system is disclosed for automatically processing workpieces requiring more than one stitch pattern. The system is operative to automatically select one of a number of previously assigned stitch patterns when a workpiece is presented for sewing. The automatic selection is accompanied by an incremental pointing to the next stitch pattern which is to be sewn when the workpiece is again presented for sewing.

Abstract: A method of treating shoe parts having a coating of a moisture-curable composition utilizes an apparatus in which a support (16) for an article, e.g. a lasted shoe S, can be supported within a chamber (30) in which the support can be enclosed. The chamber (30) is supplied with heat and moisture. More especially, the article is subjected to infra-red radiation from a heater (44) and steam is supplied to the chamber (30) such that the humidity of the atmosphere within the chamber (30) is maintained during the operating cycle at a dew point of between 50.degree. and 60.degree. C. The surface temperature of the heater (44) is between 250.degree. and 420.degree. C., preferably between 300.degree. and 380.degree. C., and the article is subjected to infra-red radiation for a period of between 5 and 25 seconds, preferably 10 seconds. Because the chamber (30) is enclosed, steam is supplied for only the first 5 seconds of the heating period.

Abstract: A clamp-type heater for heating shoe upper portions prior to molding them comprises an inner metal form (18) and a co-operating outer band (26) of silicone rubber material. The form (18) is heated e.g. by a cartridge heater while the band (26) is heated by a radiant heater (36) arranged about its outer surface. When the inner form (18) carries a shoe upper portion into the band (26), the latter wraps round the portion and clamps it about the form to ensure efficient heat transfer. The temperature of the outer band (26) is sensed by a thermistor (46) which is accommodated in a tube (48) secured by adhesive to the outer surface of the outer band. More particularly, the tube (48) is secured to the band (26) by a line contact and its longitudinal axis extends perpendicular to the direction in which the band is stretched during the operation of the device.

Abstract: Shoe stiffeners are now comprising a textile fabric impregnated with a stiffening composition. In the past certain of these have been made by impregnating textile fabric with a solution of stiffening composition. Others have been made by impregnating textiles with an aqueous emulsion of stiffening composition but these have not been as stiff or creep-resistant in wear as corresponding weights of solution impregnated materials. In the invention a plasticizer (solid at wear temperatures and melting at temperatures commonly used in activating shoe stiffeners e.g. above about 50.degree. C.) and an aminoplast resin 3 to 30% based on dry weight of composition are included in the stiffening composition. The stiffeners are sufficiently stiff and creep-resistant to be satisfactory as replacements for many solution-impregnated stiffeners and may be stuck to the upper with hot melt adhesives or latex (if primed).
