ABSTRACT:
A machine for progressively roughing marginal portions of shoe bottoms comprising a shoe support (18) having toe support means (470) and a heel support arrangement including two sets of clamps (390, 392), one set (392) of which serves also as sensing means for sensing, by engagement with an off-set portion of the shoe last whether the shoe thus supported is a left or a right. An inductance sensing device (610) associated with the second set of clamps (392) supplies a signal to control means of the machine, the signal being dependent upon whether the shoe is a left or a right. The control means ensures that, in the operation of the machine, a roughing operation is carried out on the shoe bottom in such a manner that the inside waist region of the shoe bottom is traversed always in the same directiion, regardless of whether the shoe is a left or a right (and of course similarly the outside waist region is consistently operated upon). In this way, uniformity of rough as between left and right shoes can be achieved.
