  • Patent number: 8540502
    Abstract: A shoe mold set includes a mold, a movable block and an adjustment unit. The mold is connected to the movable block, and both are slidably between two rail members of the replacement unit. The replacement unit is connected with the adjustment unit which is adjustably located between the top board and the bottom board of the replacement unit.

  • Patent number: 5722103
    Abstract: A machine for lasting the toe and side and heel of an upper to an insole mounted to a last includes a toe and ball wiper assembly and a heel and shank wiper assembly in combination with a pincer assembly mechanism for stretching the upper tightly about the last and a toe clamping mechanism for clamping the stretched upper against the last. Following stretching and clamping, the toe wipers are actuated to press the upper margins against the insole bottom against the counter force of an overhead toe hold-down acting against the top of the upper. A brake mechanism fixes the overhead hold-down to maintain the toe wiping plane in a constant position. The heel wiper assembly is elevated within the machine to locate the heel wiper plane at a proper height relative to the insole bottom, the proper height being determined with a sensor mounted for movement with the heel wiper assembly. A heel clamping pad assembly connected to the heel wiper assembly then clamps the heel prior to stretching of the upper.

  • Patent number: 5271117
    Abstract: The machine comprises a shoe support (20) for e.g. a heel seat and side lasting machine has a last pin (24) on which a shoe may be positioned, bottom up, having a shoe heel end positioning mechanism (86) including a heel height gauge device (110) for locating the heel end of the shoe to lengthwise and heightwise datums, and a toe support (30), including an abutment (54) for setting a toe height datum (54a), each of said datums being adjustable according to the style of shoe being operated upon. The machine also includes a heel band mechanism (150), the arrangement being that the shoe heel end positioning mechanism (86) is moved to an out-of-the-way position after the shoe has been positioned, thus allowing the heel band mechanism (150) to move into shoe engagement. The shoe is held by auxiliary clamp means (184) during this changeover.

  • Patent number: 5210897
    Abstract: For accurately positioning a shoe upper on its last preliminarily to a pulling over and toe lasting operation, the machine comprises an optical scanning system (20) by which, in cooperation with a central processor unit (22), coordinate axis values can be determined for selected portions of the topline region of the shoe upper (the "actual" values) and be compared with a set of taught data relevant to the shoe style, such taught data representing the positions in which the selected portions of the topline region of the shoe upper are to be located (the "should be" values), the central processor unit (22) comparing the actual and "should be" values and supplying correction signals to motors (16) associated one with each of the pincers (10, 12) whereby the shoe upper is selectively tensioned in order to achieve the desired location of the topline region of the shoe upper on its last.

  • Patent number: 4924546
    Abstract: The pulling over assembly (2, 39) and lasting assembly (13, 40) of a pulling over and lasting machine are capable of being moved apart to enable a pulling over operation to be effected on one shoe at a first station (I) while a lasting operation is being completed on a further shoe at a second station (II). In one embodiment the pulling over assembly (2) moves bodily to the second station (II) at which the lasting assembly (13) is arranged; in a second embodiment the lasting assembly (40) moves to the first station (I) at which the pulling over assembly (39) is arranged. Each assembly (2, 13; 39, 40) has a heel rest (5, 19; 41, 50), the heel rests being so arranged as to carry out without collision the function of holding the shoe against lengthwise displacement.

  • Patent number: 4920594
    Abstract: The apparatus comprises a pulling over and toe lasting machine and a side and heel seat lasting machine. The pulling over and toe lasting machine comprises two linear potentiometers (102, 104) for monitoring the movement of the heel rest (26) both lengthwise and heightwise of a shoe, a left/right sensor (PrS2) and a proximity switch (PrS1) which senses when the wiper plates (20) reach a predetermined position in their inwiping movement and causes output value information from the potentiometers (102, 104) and left/right sensor (PrS2) to be "read". The side and heel seat lasting machine comprises two side lasting assemblies (36) tiltable in a direction lengthwise of the shoe, to accommodate to the spring of the last, and two adhesive-applying nozzles (40) arranged to track along opposite portions of the shoe. A further linear potentiometer (146) monitors the nozzle movement, and stepping motors (66) are provided for effecting tilting movement of the assemblies (36).

  • Patent number: 4517457
    Abstract: Photo electric sensors, located in a supporting body, are mounted in association with selected one of the plurality of mold sections in a lasting machine. The photo sensors include a light source and a mirror in one housing and a transistor and a mirror in a second housing. The housing being arranged so that the mirrors transfer the light across the gap between the gap between the plier bodies intersecting the path of movement of the associated clamping jaw. The sensors sense the actual position of the work piece in the mold and provide a signal thereof.

  • Patent number: 3940816
    Abstract: Side lasting apparatus comprising a support for supporting a last, bottom side up and lasting instrumentalities supported at opposite sides of the last support between which a last mounted on the support with the lasting margin of an upper thereon projecting upwardly from the bottom is adapted to be moved by the support and wherein said instrumentalities are yieldably displaceable laterally and vertically by entrance of the last therebetween. There are flexible elements carried by the instrumentalities conformable to the shoulders of the last at each side by such displacement to fold the lasting margin inwardly over the bottom of the last as the last is moved between the instrumentalities.
