摘要:
A method of string lasting a shoe upper and providing an upper with a lasting string at its lower edge by means of which the lower edge is adapted to be drawn inwardly against the bottom of a last or form preparatory to injection molding of an outsole thereto and with lasting extensions at the lower edge, one at each side in the region of the shank for drawing the upper at the shank inwardly across the bottom of the last or form to conform the upper to the last or form at the shank.

A MACHINE FOR STRETCHING AN UPPER ABOUT THE LEVEL END OF A LAST AND CLAMPING THE HEEL PORTION OF THE UPPER TO THE LAST PRIOR TO WIPING THE MARGIN OF THE HEEL PORTION OF THE UPPER AGAINST AN INSOLE LOCATED ON THE BOTTOM OF THE LAST. THE MECHINE INCLUDES A U-SHAPED CLAMP PAD HAVING PAD LEGS MOVABLE TOWARDS THE LAST TO EFFECT THE CLAMPING AND PINCERS MOUNTED TO THE PAD LEGS OPERATIVE TO GRIP THE BREAST LINE PORTIONS OF THE UPPER MARGIN PRIOR TO MOVEMENT OF THE PAD LEGS TOWARD THE LAST.
摘要:
The method of shoe making which comprises placing an insole on the bottom of a last, string-lasting an upper onto the last over the exposed face of the insole while holding the inner side of the lasting margin spaced from the edge face of the insole and thereafter forming an outsole against the insole and lasting margin of the upper by injection molding.
摘要:
The process of shoemaking by which the steps of molding a flat mulled insole by direct contact to the contoured bottom of a wooden last and at the same time completing the shoe by forming an outsole and bonding it to the molded insole.
摘要:
A combined heel, forepart and cement-lasting machine having a last holder and a carriage. The carriage carries a heel-band, a pair of wipers and the like, and also a tripping blade which is associated with a switch. The switch controls a motor which displaces the last holder in a direction towards the tripping blade. The switch stops the motor when the last holder comes in contact with the tripping blade wherein the last holder is in a precise position to apply cement to proper locations on the last. The tripping blade is also adjustably disposed on the carriage to adjust the position of the last with respect to the edge of the wiper in the operating position of the last holder.
摘要:
A shoe lasting machine having pneumatically operated wipers, in which a piston operatively connected to the wipers is automatically stopped by pneumatic circuitry at a predetermined intermediate position in its wiper operating movement so that the upper has been wiped over a shoe bottom only enough to hold an insole against the last bottom, after which an insole plate which previously held the insole is retracted and controls continued operation of the piston and movement of the wipers.
摘要:
Shoes are constructed on a last by loosely placing an upper over the last and properly centering it thereon by bringing marks on the upper and the last into registration, loosely pulling the centered upper over the last, clamping the upper to clamping implements, successively stretching the upper longitudinally and laterally by the implements, and attaching the lip of the upper to the insole on the last.
摘要:
A shoe lasting machine having a support on which the toe of the last may be placed and held and instrumentalities at the toe for operating on an upper and insole assembled on the last, said instrumentalities comprising adjustably mounted pincers adapted to grip the lasting margin at the tip, along the sides and at the waist and to pull it taut about the toe and forwardly with reference to the heel, and wipers for wiping the lasting margin inwardly against the insole.
摘要:
A MACHINE FOR WIPING THE MARGIN OF THE TOE PORTION OF AN UPPER DRAPED ABOUT A LAST AGAINST AN INSOLE LOCATED ON THE BOTTOM OF THE LAST. THE WIPING IS PERFORMED BY WIPERS, HAVING A TOE TO HEEL COMPONENT OF MOVEMENT, THAT PERFORM THEIR WIPING OPERATION IN RESPONSE TO THE ENGAGEMENT OF A HEEL CLAMP WITH THE HEEL PORTION OF THE LAST WHILE THE HEEL CLAMP IS LOCKED AGAINST MOVEMENT AWAY FROM THE LAST.
