A shoe having the appearance, but not the construction, of a compo cement shoe has an upper, an inner sole stitched to the lower peripheral portion of the upper, and an outer sole attached to the underside of the upper and inner sole.In the method for manufacturing such shoes the pieces of the upper are first sewn together, the toe portion of the upper is crimped, gathered, and stitched and the inner sole is then positioned coplanar with the lower peripheral portion of the upper in the area circumscribed by the lower peripheral edge of the upper and sewn thereto. Finally, an outer sole is attached to the combined upper and inner sole assembly.
摘要:
A pulling over mechanism having pincers for gripping the margin of an upper mounted on a last for stretching the upper about the last pursuant to relative heightwise movement of the last with respect to pincers. A motor is actuable to move the pincers heightwise and a handle is so connected to the pincers as to lower the pincers in response to movement of the handle and to thereafter be disconnected from the pincers.
摘要:
Working devices of shoe manufacturing machines are adjusted according to the size of the shoe and also whether a right or left shoe is concerned by first identifying these items and by transmitting this information to a device which automatically adjusts the working devices to the proper position.
摘要:
An apparatus for lasting footwear, including a rotatable roll that is articulated on a spherical joint to permit the roll to adapt to and last any curvature it encounters on the insole of any shoe assembly it is operating upon.
摘要:
A shoe lasting machine having helically landed rolls for wiping opposite margins of a shoe upper. The rolls extended widthwise and are angularly disposed so the roll surfaces facing the shoe bottom generally correspond to the widthwise curvature of the shoe bottoms, the rolls being rockable in a heightwise extending plane in unison as they traverse lengthwise along the shoe bottoms.

1. A CEMENT APPLYING MECHANISM COMPRING: SUPPORT MEANS FOR SUPPORTING BOTTOM-UP A SHOE ASSEMBLY THAT INCLUDES A LAST HAVING AN INSOLE LOCATED ON ITS BOTTOM AND AN UPPER MOUNTED THEREON, AT LEAST ONE END PORTION OF THE MARGIN OF THE UPPER HAVING BEEN WIPED AGAINST THE ISOLE AND AN UNWIPED PORTION OF THE UPPER MARGIN EXTENDING REARWARDLY OF SAID WIPED END PORTION AND EXTENDINGLY UPWARDLY OF THE CORRESPONDING PORTION OF THE INSOLE PERIPHERY; A NOZZLE, LOCATED ABOVE THE SHOE ASSEMBLY, MOUNTED FOR FORWARD-REARWARD MOVEMENT; MEANS FOR APPLYING A YIELDABLE DOWNWARD FORCE AND A YIELDABLE OUTWARD FORCE TO THE NOZZLE SUCH AS TO CAUSE THE NOZZLE TO BEAR AGAINST THE INSOLE IN THE CORNER BETWEEN SAID UNWIPED UPPER MARGIN PORTION AND SAID CORRESPONDING PORTION OF THE INSOLE PERIPHERY REARWARDLY OF THE BOUNDARY BETWEEN SAID WIPED AND UNWIPED PORTIONS; (SAID WIPED END PORTION AND SPACEDLY FROM SAID UNWIPED PORTION OF THE UPPER MARGIN AND SAID CORRESPONDING PORTION OF THE INSOLE PERIPHERY; MEANS FOR THEREAFTER APPLYING A YIELDABLE OUTWARD FORCE TO THE NOZZLE, WHILE THE DOWNWARD FORCE IS MAINTAINED, TO CAUSE THE NOZZLE TO MOVE INTO THE CORNER BETWEEN SAID UNWIPED UPPER MARGIN PORTION AND SAID CORRESPONDING PORTION OF THE INSOLE PERIPHERY REARWARDLY OF THE BOUNDARY BETWEEN SAID WIPED AND UNWIPED PORTIONS;) MEANS FOR THEREAFTER MOVING THE NOZZLE FORWARDLY, WHILE SAID DOWNWARD AND OUTWARD FORCES AND MAINTAINED, UNTIL THE NOZZLE ARRIVES AT SAID BOUNDARY; MEANS FOR THEREAFTER MOVING THE NOZZLE REARWARDLY, WHILE SAID DOWNWARD AND OUTWARD FORCES ARE MAINTAINED, AND FOR CONCOMITANTLY EXTRUDING CEMENT THROUGH THE NOZZLE, UNTIL THE NOZZLE ARRIVES AT A DESIRED LOCATION ALONG SAID UNWIPED PORTION OF THE UPPER MARGIN TO THEREBY CAUSE THE CEMENT TO BE EXTRUDED ALONG THE ENTIRE LENGTH OF SAID UNWIPED PORTION OF THE UPPER MARGIN BETWEEN SAID BOUNDARY AND SAID DESIRED LOCATION INTO SAID CORNER; AND MEANS FOR THEREAFTER (MOVEING) MOVING THE NOZZLE INWARDLY OF SAID CORNER AND FOR RAISING THE NOZZLE UPWARDLY OF THE INSOLE.
摘要:
A lasting machine that applies cement into the corner between a portion of the margin of an upper mounted on a last and an insole located on the last bottom and that wipes the margin portion against the insole so as to cementatiously attach the wiped margin portion to the insole.
摘要:
Apparatus for string lasting the uppers of shoes or boots has a power operated device for pulling the string. Clamping means, conveniently one or more bollards, are provided for holding the string and are mounted on a linear actuator such as pneumatic piston and cylinder device. The actuator is either carried by the base on which the last is mounted or is independent thereof and movable into a position where it reacts against the last.
摘要:
A mechanism for applying cement in the corners between the unwiped side portions of an upper margin, that is mounted on a last, and the corresponding side portions of the periphery of an insole that is located in the last bottom. The upper margin side portions are located between the previously wiped toe and heel portions of the upper margin. The mechanism includes a pair of nozzles that travel in unison along the entire lengths of the corners, while the last is supported bottom-up, from the boundaries of the side portions of the upper margin with the wiped toe portion of the upper margin and the boundaries of the side portions of the upper margin with the wiped heel portion of the upper margin. During this travel, the nozzles are yieldably urged downwardly of the insole and outwardly into the corners and the nozzles are mounted to enable them to have relative movement with respect to each other lengthwise of the last so that they can affect this relative movement when arriving at the boundaries.
