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

An arrangement for applying adhesive to insoles of shoes in a lasting operation comprising a U-shaped applicator having passages therethrough for extruding cement upon the insole. An array of criss-crossed channels drain surplus adhesive from the extrusion arrangement. The extrusion arrangement includes V-shaped grooves which apply the adhesive to the insole.

Adhesive applying arrangement for the insoles of shoes

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.
