<p>A method for roughing the underside of footwear along a pre-established path, in which, in pre-established positions of the path, the roughing machine is disposed substantially parallel to the path in the point of contact between the roughing wheel and surfaces to be roughed and slanting sideways in relation to the convexity in such point of the surface to be roughed. A machine applying the method comprises a support (12) for the footwear to be roughed, a rotary roughing machine (14) having a peripheral roughing surface, means (17-20) for driving the roughing machine in its movement and its orientation along the pre-established path controlled by programmable control means (16). The control means, in pre-established positions of the path, control the means for moving the roughing machine to dispose the roughing machine in a position substantially parallel to the path in the point of contact between the roughing machine and surfaces to be roughed and slanting sideways in relation to the convexity in such point of the surface to be roughed. <IMAGE></p> |
