ABSTRACT:
A side and heel lasting machine. The machine serves to adhere the unwiped margin of a shoe upper assembly, whose toe portion has been wiped, to the periphery region of the assembly insole. Lasting pads are employed to keep the margin in position during application of adhesive from nozzles that are spring loaded to press outwardly and track the upstanding margin when adhesive is applied in the region between the insole and the margin. The pads are then raised and urged inwardly to press the margin onto the insole. The top edge of inner lasting pads are folded onto the insole to achieve during wiping action; the direction of forces upon the top edges of the lasting pads is changed during wiping to increase downward wiping forces upon the margin. A quick-release mechanism is provided to permit removal and replacement of the lasting pads without need to remove any screw-type fasteners.
