SELF-ADJUSTING ROLL WIPERS FOR A SHOE LASTING MACHINE

摘要

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.
