In a pulling over and toe lasting machine, the pincers first grip the lasting margin above the wiping plane, whereafter the upper is tensioned about its last by upward movement of the last support, from an initial, lowered, position to a position in which the last bottom is in the wiping plane, and by downward movement of the pincers. The machine also comprises auxiliary means by which any wiper remaining in the wiping plane after the upper has been tensioned as aforesaid can be moved downwardly out of said plane so as not to impede the in-wiping movement of the wipers. When the auxiliary means is actuated, furthermore, the gripping force applied by the pincers to the upper is reduced to allow slippage of the upper in the pincers.

Shoe lasting machine

A shoe machine for pulling and lasting shoe uppers and insoles on lasts has a pair of wiping elements, one operating heelwardly of the other in the joint region. After the upper has been pulled over and the insole has been cemented, the first wiping elements wipe in the upper margin at the joint with a toeward motion, which wiping elements then retract. The second wiping elements wipe in adjacent portions of the lasting margin, the wiping action of the second wipers overlapping that of the first wiping elements to wipe down any creases formed thereby. The main toe wiper plates operate to wipe in the toe and forepart portions of the upper. The insole cementing plate has heelward extensions hinged thereto which are yieldably urged upward by springs. Cement is fed to the extensions via passageways in their connective pivot pins.
