Abstract:
In a method of moulding a sole of a plastic material and a welt on a shoe upper (1) a mould (3) is used. The mould (3) includes at last (2), upon which a shoe upper (1) is arranged, an upper mould part (5) divided along a longitudinal middle plane and thus includes two halves (5a, 5b) being laterally movable in relation to the lower mould part (4) between an open and a closed mould position, and a lower mould part (4) being vertically movable in relation to the upper mould part (5) between an open and a closed mould position. For carrying out the method an annular shoe welt (6) is provided and arranged in the mould in the mould's open position. The two halves (5a, 5b) of the upper mould part (5) are closed and the lower mould part is moved into its closed position. As a result a circumferential support surface (7) on the upper face of the lower mould part (4) co-acts with a pressure surface (17) on the lower face of a projection (15) on each half (5a, 5b) of the upper mould part such that the portion of the welt (6) facing the shoe upper (1) it tilted inwards and downwards to bring the inner end face of the welt (6) into sealing engagement with the lower side section of the shoe upper (1). The shoe sole is then moulded in a manner known per se by supplying a plastic material to the cavity of the mould.

Abstract:
An orthopedic casting slipper kit (21) including a resilient fabric impression slipper (23) formed to extend on a patient's foot (27) from a plantar aspect or surface (29) to about one-third of the way from the base of the toes to the dorsum of the foot. A longitudinally resiliently extensible band (37) is provided on the slipper (23) proximate the open end (33), and an arch strap (39) dimensioned to span transversely over the dorsum (30) of the foot (27) is used to pull the impression slipper (23) up into contact with the arch (35) of the foot to prevent bridging of the arch. A method of using the arch strap (39) to aid in conformance also is disclosed.
Abstract:
A method of making a shoe. The shoe having an upper (131), an insole (133), an outsole (135). The method involves forming a cavity (137) in the outsole (135), affixing the cushioning pad (29) in the cavity and injecting molding (138) the elements together.
Abstract:
A seamed structure formed with seams which are soak- and leak-resistant to be suitable for three-dimensionally shaped, processed products such as shoes and the like, and a method of forming the same. The seamed structure has a feature in that a face material and a back material are seamed along seam lines through a hot melt adhevise resin layer, sewing needle holes defining the seam lines are filled with a part of a resin of the hot melt adhesive resin layer, and the face material is water-proof. The seamed structure can be prepared by a method which includes the following processes: (A) a process of preparing a precursor seamed layer structure by sewing the water-proof face material and the back material at least along the seam lines with a specified hot melt adhesive resin sheet between them; (B) while pressing the seamed layer structure by means of surfaces of a specified pressure plate body, applying sufficient high-frequency voltage to melt the hot melt adhesive resin sheet, thus fluidizing only the hot melt adhesive resin sheet and having a part of the resin sheet enter and fill into the sewing needle holes which constitute the seam lines. An embodiment of a method of forming the seamed structure is disclosed together with a high-frequency heating processing device, which is suitable for processing of shoes.
Abstract:
A forming mould for an insole enclosing an uneasy deformable material interlayer (30) comprises an upper die (40) and a lower die (50) cooperating with the upper die (40). The upper die (40) is provided with a die body (41) comprising of an upper main die (42). The lower die (50) is provided with a die body (51) comprising of a lower main die (52). The upper main die (42) is provided with a concave (43) having the same shape as the shape of the insole. The circumference of the lower main die (52) is provided with a side die (53). A linear frame (54) higher than the surface of the lower main die (52) is protruding and extending upward from the side die (53) to position the insole rapidly. After the upper die (40) and the lower die (50) being pressed together, the linear frame (54) of the lower main die (52) is cooperated with the concave (43) of the upper main die (42) and there-between remains a holding space for holding the uneasy deformable material interlayer (30). The side die (53) of the lower die (50) is cooperated with the circumference of the concave (43) of the upper main die (40) to press the easy deformable material of the insole.
Abstract:
A method for making an article of footwear is disclosed. The method can include a number of steps where various molds are used to attach or mold a tread element onto a substrate or matrix lining. The tread element can be formed by compressing a rubber block between various molding members to liquefy and cause the resulting rubber material to flow into at least one lug cavity disposed near the matrix lining. The rubber material eventually enters the lug cavity and becomes attached to the matrix lining.
Abstract:
The invention is a new rotary support structure for moulds, with circular or annular rotating plane (O2), on which various moulds are installed (S), said structure being equipped with a single mould opening mechanism (U 1a, U 1b) and a single mould closing mechanism (U2a, U2b). On the circular plane (02), at the level of each pair of mould halves (Sa, Sb), there are several locking devices (C) that slide radially and are formed by two elements (C1, C2) with opposing C-shaped sections constrained to each others. The upper half of the mould (Sa) is integral with one or more sliding rods (Bs) generically orthogonal to the circular or annular plane (O) and having the lower end provided with a sliding block (Bp) suited to slide on a rail (F5) positioned below the circular or annular plane (O).
