a shoe machine having nozzles for applying adhesive progressively to the margin of a shoe bottom , in which the nozzles are moved heightwise to engage a guide of the nozzle with the edge of the shoe bottom maneuvered by an arrangement of piston and cylinder members , and a sensing device associated with a stop mechanism for control and guidance to enable the nozzles to follow the marginal contour of the shoe bottom to apply adhesive thereto , and thence to return the nozzles to their start position to begin another cycle .
