  • Patent number: 5205009
    Abstract: A shoe support for supporting lasts of a wide range of sizes comprises two support members in the form of spaced-apart bars (38) each of which can pivot at an axis (36) extending adjacent an elongated edge of its associated bar so that the distance between the ends of the bars can be varied. Instead of bars (38), plate members (138) may be used, dimensioned so as to provide a substantially continuous support surface, for e.g. shoe components, when pivoted to a horizontal position. For maintaining the support members (38;138) in adjusted position, furthermore, a friction arrangement (40,42; 144,146) is provided. The shoe support is especially suitable for use in a shoe transporter system forming part of a drying apparatus in which the bottoms of shoes and/or shoe components to which a coating of e.g. adhesive has been applied can be supported by the shoe supports with the coated surfaces exposed to turbulent air and heat.

  • 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.
