Shoe lasting machine

A machine for lasting side portions of shoes, comprising:

• a shoe support arrangement by which a last carrying a shoe upper and an insole can be supported, adhesive applying means, means for effecting relative movement, in a direction extending heightwise of a shoe supported by the shoe support arrangement, between the shoe support arrangement and the adhesive applying means, between an operative condition of the adhesive applying means, in which said means contacts the insole of a shoe supported by the shoe support arrangement, and a retracted condition of said means;
• means for effecting relative movement, in a direction extending lengthwise of a shoe supported by the shoe support arrangement, between the shoe support arrangement and the adhesive applying means, the adhesive applying means comprising two nozzles arranged, when in operative condition, to operate along opposite sides of a shoe supported by the shoe support arrangement and being movable in a direction extending widthwise of such shoe, thus to apply adhesive progressively between lasting marginal portions of the upper and corresponding marginal portions of the insole of such shoe while following the edge contour thereof, as relative lengthwise movement is effected as aforesaid;
• an arrangement of side lasting instrumentalities by which the lasting marginal portions of such shoe upper can be wiped over the corresponding marginal portions of the insole and pressed thereagainst, thus to secure said portions together by the adhesive applied therebetween, wherein means is provided for moving each nozzle, independently of the other, in a direction extending widthwise of such shoe as aforesaid, and thus for urging each nozzle to follow the edge contour of such shoe, and wherein one of the nozzles has stop means associated therewith by which, when in an operative position, the position of said nozzle, widthwise of the shoe, can be determined, the arrangement being such that, at the start of a cycle of operation of the machine, with the nozzles in retracted condition, and with the stop means in its operative position, said one nozzle is positioned by said stop means and the other nozzle is positioned adjacent said one nozzle, and thereafter, with the nozzles in operative condition, said stop means is moved to a retracted position, thus to allow the nozzles to follow the edge contour of such shoe, as relative lengthwise movement is effected between the shoe support arrangement and the adhesive applying means.
