  • 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: 4879778
    Abstract: A heel molder to form the heel part of a footwear upper assembly. The heel part includes a thermally-activated material that is deformable when heated above a threshold temperature; it is non-deformable below that threshold temperature; it is non-deformable at room temperature. The material preferentially includes a thermally-activated adhesive, that is, an adhesive that becomes tacky or sticky at or about the temperature at which the material becomes deformable. The heel molder receives the upper assembly, forms the same at the heel region while the material is above the threshold temperature, cools the material whereby the thermally-activated material--and the upper itself and liner--takes a permanent preformed set as a laminate for later operations. According to the present teaching, the thermally-activated material or counter, the upper and the lining of the upper typically form, when cooled, a laminate that retains its geometry for subsequent operations thereon.

  • Patent number: 4866802
    Abstract: In an integrated system to achieve a number of operations on a footwear upper assembly, an automatic rougher that includes a roughing tool adapted to remove material--and hence rough--the cement margin (or bonding surface) of the footwear upper assembly to provide a cementing surface onto which an outer sole is later applied. The cement margin (or bonding surface), as is known in this art, typically follows a closed-loop path that rapidly changes in all directions of an X-Y-Z coordinate system and the roughing tool must be continuously re-oriented to the many direction changes of the cement margin in order to track the margin. According to the present teaching the upper assembly, and hence the cement margin thereof, is ordinarily moved in rotational movement, rocking movement, transverse translational movement, and, also, vertical translational movement (i.e., movement toward and away from the roughing tool) during the course of roughing.

  • Patent number: 4769866
    Abstract: For use in a system that includes first and second machines to perform operations on a footwear upper assembly, a transfer machine that includes an activator arm assembly, and a gripper assembly rotatably and pivotally connected to one end of the activator arm assembly. The gripper assembly includes a pair of fingers with a gripper jaw pivotally secured to each of the fingers. The pair of fingers are movable toward and away from each other respectively to grasp and release the footwear upper assembly. The pivotal attachment of the jaws permits the jaws to adjust to the irregular profile of the footwear upper assembly, a situation which is enhanced by the geometry of the gripper jaws which permits contact between the jaws at regions spaced longitudinally along the footwear upper assembly and by choosing a jaw material that is soft enough to deform, and hence provide larger contact area between the upper assembly and the jaws.
