Abstract
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.
