A machine for applying resinous stiffening material to the heel pocket portion of a shoe upper, and for holding a liner portion thereattached, away from the upper heel and sides by a liner extender as the resinous material is being applied, and then wiping the liner against the resinous upper while liner extender is being withdrawn from between the layers of material. The liner extender is comprised of a loop member articulately upwardly and outwardly from a nozzle as it advances to the heel pocket articulately downwardly and backwardly toward the nozzle during completion of the application of resinous material between the flexible layers of the shoe upper.

Shoe upper liner extender mechanism

A V-shaped shell comprising a replaceable tip for a mold apparatus utilizable for squeezing a shoe upper against a female mold. The V-shaped shell comprises generally planar members meeting at a curvilinear apex, each planar member having a raised periphery which tapers inwardly towards the surface of the planar member, to define a pre-arranged volume for the tapered distribution of stiffening resin applied between the inner liner and outer layer of a shoe upper.

Shoe upper cavity shell

A device for stiffening portions of sheets of flexible material including a reciprocable and rotatable nozzle disposed upon an extruder, the nozzle having a generally V-shaped nose section and a pair of wings disposed therebehind.
