Abstract of the Disclosure A multi-station machine for marginal roughing and toe scouring of shoe bottoms has a turret arrangement, carrying a plurality of shoe supports. At a marginal roughing station two rotary roughing tools operate along opposite marginal portions, during movement of the tools lengthwise of the shoe bottom respectively in a first and a return direction, the shoe support being movable heightwise and widthwise of the shoe bottom so that each tool follows the shoe bottom margin contour. The tools can also pivot about a horizontal axis to maintain their plane normal to the shoe bottom portion being operated upon. In-machine brush grinding is provided, using rotating stones, the speed of rotation being about twice that of the roughing brushes, and the direction of rotation such that the perpheries of stone and brush, at the point of contact, move in the same direction. At a toe scouring station a single abrasive roll is movable lengthwise and heightwise of the shoe bottom under the control of a cam the angular disposition of which is set according to the shoe bottom contour. For controlling the movements of both the tools and shoe support at the marginal roughing station, servomotors are provided under the control of computer control means which supplies control signals thereto in accordance with a programmed instruction.
