Abstract: A device for toe and ball lasting a shoe unit consisting of a last with a shoe upper superimposed thereon and an insole arranged on the last bottom comprises main wipers seated above the shoe support for linear movement and pivotal movement about a fulcrum point and carrying, on their side opposite the fulcrum point, ball wipers arranged for longitudinal displacement.In order to achieve perfect wiping results in the ball area, irrespective of the length, i.e., size of the shoe unit being processed, without the need to perform troublesome adjusting or setting work on the wipers, the device is provided with a sensing element for scanning the length of the shoe unit placed upon the shoe support, and for emitting a signal indicative of the length of the said shoe unit, the said sensing element coacting with adjusting means which are controlled by the said signal and which serve to automatically adjust the initial position of the ball wipers on the main wipers to the respective length of the shoe unit.

Abstract: A roughing machine operable to rough the margin of an upper of a shoe assembly that comprises a last having an insole located on its bottom and the upper mounted thereon with the upper margin lying against and being secured to the bottom of the insole. The shoe assembly is supported bottom-up on a shoe assembly support and the shoe assembly support is so moved as to move succeeding portions of the upper margin past a roughing tool. During this movement of the shoe assembly support, the shoe assembly support is caused to rock to thereby rock the shoe assembly.
