Heel lasting machine

Abstract

A heel lasting machine to receive a footwear upper assembly that includes a last, an insole on the last bottom and an upper draped about the last with a margin extending upwardly from the insole, the last having a spindle hole. The machine includes two stations; each station includes a heel post or spindle having a last pin to insert into the spindle hole and a toe rest to receive the toe of the upper assembly. A single adhesive applicator applies adhesive to the heel region of the upwardly directed insole of both upper assemblies. All operations of the machine are computer controlled. A mechanism is provided to locate the nozzle of the adhesive applicator in its rest position relative to the heel region, despite variations in the placement of the spindle hole. A mechanism to assure a snug fit of the heel of the upper about the heel of the last is also provided. Once the upper is fitted about the last the upper assembly is pressed onto the toe rest. Thereafter further machine elements further secure the upper assembly to the machine, a U-shaped ribbon of adhesive is applied to an appropriate location at the heel region of the insole and the upper margin is wiped thereon.
