Abstract:

A machine for lasting sides and heels of a shoe assembly having a last with an upper mounted thereon and an insole at its bottom, the assembly being one whose toe portion has already been wiped and whose side and heel portions are to be wiped. Nozzles serve to apply adhesive as a ribbon into the region between the insole and the unwiped margin at and near the insole periphery. A lasting mechanism provides backup to the margin to permit the nozzles to press outwardly against and track the margin. Later the lasting mechanism applies inward and downward pressure onto the margin. The lasting mechanism includes a lasting instrumentality at each side of the shoe assembly. Each such instrumentality includes an inner, an intermediate and an outer flexible lasting pad; each pad has relatively rigid segmets at its top edge; and each is moved by air cyliers to perform its function. The inner lasting pad performs a backup function during application of adhesive and a wiping function. Its relatively rigid segments are attached to the respective air cylinders by a clevis and pin arrangement which permits the relatively rigid segments to rotate through about ninety degrees between the backup function and the wiping function.
