<p>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 a 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 acutated, furthermore, the gripping force applied by the pincers to the upper is reduced to allow slippage of the upper in the pincers.</p> |
