ABSTRACT:
A side and heel lasting machine that serves to adhere the upstanding unwiped side and heel margin of a shoe upper assembly, which assembly includes a last with an insole on the last bottom and an upper draped about the last. The toe portion of the upper assembly has previously been wiped to the periphery region of the assembly insole. A pair of pincers, one disposed at each side of the upper of the assembly, grasps the upstanding unwiped margin and draws it upwardly, inwardly and forwardly (i.e., towards the toe thereof) to fit it snugly about the last. Lasting pads are employed to keep the unwiped margin in position during application of adhesive from nozzles that are spring loaded to press outwardly and track the upstanding unwiped margin when adhesive is applied in the region between the insole and the margin. The upstanding side and heel margin is then wiped onto the insole.
