A combined heel seat lasting and side lasting machine comprising heel seat wipers and helically ribbed rotatable side lasting rolls, for automatically lasting the side and heel portions of shoe assemblies. Shoe assembly support means comprising a movable jack mounted in a carriage presents a previously toe lasted shoe assembly to the side lasting rolls and the heel seat lasting wipers in sequence.

Automatic heel and side lasting shoe machines

A shoe lasting machine having helically landed rolls for wiping opposite margins of a shoe upper. The rolls extend widthwise of the shoe bottom and are supportively disposed so the roll surfaces facing the shoe bottom generally correspond to the widthwise curvature of the shoe bottoms, the rolls being arcuately movable, permitting a controllable change in the included angle therebetween in order that they may accommodate wide ranges of transverse curvatures of shoe bottoms.

Self-adjusting roll wipers for a shoe lasting machine

A shoe machine having nozzles for applying adhesive progressively to the margin of a shoe bottom, in which the nozzles are moved heightwise to engage a guide of the nozzle with the edge of the shoe bottom maneuvered by an arrangement of piston and cylinder members, and a sensing device associated with a stop mechanism for control and guidance to enable the nozzles to follow the marginal contour of the shoe bottom to apply adhesive thereto, and thence to return the nozzles to their start position to begin another cycle.
