Cement applying mechanism

Abstract

A mechanism, operable on a shoe assembly comprised of a last having an upper mounted thereon and an insole located on its bottom, for applying cement in a cement applying stroke along the corner formed by the upper margin and the insole periphery between an initial location at a boundary between the lasted toe portion of the shoe assembly and an unlasted side portion of the shoe assembly and a final location at the heel end extremity of the shoe assembly. The cement is applied by a nozzle that is movable rearwardly in the cement applying stroke and that is swingable about a heightwise axis during its rearward movement. The cement is applied from the nozzle into the corner through a passage that extends radially from the upright axis. At the beginning of the cement applying stroke the passage is directed laterally and outwardly of the axis and the nozzle is caused to so swing rearwardly and inwardly during the latter part of the cement applying stroke that the passage is directed generally rearwardly from the axis when the nozzle has arrived at the final location.
