    摘要: Automatic guiding apparatus has first and second drive wheels which are driven from a common source for effecting feeding of a workpiece in a straight line through a machine. For effecting steering of the workpiece along a line parallel to the edge, a sensor senses the edge, a computer calculates the speed differential required to be imparted to the two drive wheels for steering about the centre of curvature of the edge, and an adding device superimposes additional positive or negative speed on one of the drive wheels. The adding device can be mechanical, such as a differential gearbox, where the wheels are driven from a common motor, or a frequency shifter where the wheels are driven by separate stepper motors supplied with pulses from a common oscillator. Automatic speed control is incorporated for negotiating sharp corners. The drive wheels are parallel to each other. In an alternative embodiment, a pair of drive wheels feed the material through the machine with one edge in engagement with a stop and an auxiliary wheel, controlled by a servo and edge sensor, is driven in opposite directions transverse to the direction of feed for effecting steering.

    摘要: A method of shoe manufacture involving welding together component parts of a blank and subsequently preforming and finishing. In one form the lining is joined to the outer by a tear-seal weld extending along the top line so that at least some lining extends unbroken across the weld line to permit preforming, the waste material being subsequently torn away. Another feature involves joining an insole portion to an outer portion, preforming and removing a gusset from the insole so as to give to the insole the requisite shape and area of a finished shoe insole. Lasting procedures are reduced and closing shop operations performed upon the flat blank before preforming.

    摘要: A shoe upper preforming apparatus includes a clamp for gripping the forepart of a fully closed upper to be preformed, a backpart mould, and a forepart mould. Actuators are provided for first moving the backpart mould along an arcuate path into a moulding position within the upper and thereafter moving the forepart mould into the moulding position. The movement of the forepart mould comprises bodily movement having components both upwards and forwards relative to the shoe upper and rotary movement, the bodily movement being effected initially with the toe end of the forepart mould raised, and the rotary movement causing the toe end to move downwardly as the forepart mould is brought to its final moulding position. When the moulds are in the moulding position they interfit to define a moulding surface corresponding to the whole of the upper, which surface may be in the shape of the last or a development of the shape of the last. The backpart mould may be cooled and the forepart mould may be heated or cooled according to the type of material to be formed. A gauge is provided for determining the height of the heel of the upper relative to the backpart mould when the backpart mould is moved to its moulding position, and a female back former is provided for assisting in the forming of the backpart of the upper. A wiper mechanism is included for wiping the lasting margin of the backpart of the upper beneath the backpart mould. The clamp can be formed in two halves which can be pivoted apart for accommodating different sizes of mould, which may therefore be removable from the machine, and power means may be provided for effecting the pivoting of the two clamp halves so that the upper can be loaded into the clamp in a relatively flat condition and then the clamp halves pivoted towards each other in preparation for the moulding operation.

    摘要: Methods and apparatus for making shaped upper components for a shoe, Whole upper components or upper part upper components can be made. Vacuum and pressure forming techniques for conforming initially flat material to a moulding surface are disclosed. The moulding surfaces may be of a shape whereby the preformed upper is convertible to the shape of the last merely by a bending operation. The mould shape can be arrived at by forming a sheet of resiliently bendable material such as unplasticized PVC to the last shape required to form a shell and, after removing the shell from the last, partially flattening it by spreading outwardly the opposite sides. Where a male mould is used the surface of the material which is to be the outside surface of the shoe can be in contact with the mould surface, and the preformed upper would be turned inside out after removal from the mold; where a female mould is used the surface of the material which is to be inside the shoe may be in contact with the moulding surface and again the preformed upper would be turned inside out after removal from the mould. The moulding surface may be embossed to transfer a pattern to the upper material. The material is held during the moulding operation. A device for partially cutting out the upper from the sheet of material from which it is formed may be provided, which device may also operate as a clamp for holding the material during the forming operation.

    摘要: Methods of preforming shoe uppers are provided using molds of a novel shape. The shape of the mold is such that the material is not stretched more than, in preferred embodiments, about 25 percent. The mold corresponds to the shape of the whole upper but is flatter than the last, is preferably unitary but can be in two or more parts. The methods involve heating the material and carrying out a pressure differential forming operation. Mechanical movement of the molds into the material, just prior to the vacuum forming is also described. When forming several uppers simultaneously, a template may be placed over the molds and subsequently used as a cutting guide. The difficulties of lasting in the normal way are avoided by the invention.
