ABSTRACT:
Provision is made for enabling the adhesive applying nozzles on a shoe lasting machine to be initially positioned offset from the longitudinal center line of the machine, selectively at one side or the other according to whether the shoe to be lasted is a left or a right. To this end each nozzle is movable, independently of the other, widthwise of the shoe bottom and has stop means associated therewith. At the start of a machine cycle, one stop means is in an operative position, in which its associated nozzle is in a desired offset position, while the other stop means is in a retracted position, allowing its associated nozzle to move to a position adjacent the first-mentioned nozzle. After engagement with the shoe bottom said one stop means is also retracted, so that both nozzles are then free to follow the edge contour of the shoe bottom without constraint.
