ABSTRACT:
Apparatus for the combined marginal roughing and toe scouring of shoe bottoms has a shoe support movable in an arcuate path past marginal roughing tools and a scouring tool, the roughing tools being movable widthwise and heightwise of the shoe bottom, and the scouring tool heightwise. All the movements are under the control of n.c. motors. The scouring tool thus follows a pre-determined path, giving enhanced control of the degree of scouring. To assist in accuracy, the shoe support has height datum means which, after use and subsequent to toe support means being locked in adjusted position, are moved out of the way so as not to impede the roughing and scouring.
