A shoe side or combined heel seat and side lasting machine has two side lasting assemblies, each comprising wiping elements mounted for pivotal movement, independently of adjacent elements, about first and second axes extending respectively transversely and lengthwise of the last bottom. For providing a substantially continuous wiping surface, the first axis lies in the plane of the work-engaging surface of its associated element, along the longitudinal center line thereof, when said surface lies horizontally. Also each shoe lasting assembly can pivot bodily about an axis adjacent the edge of the work-engaging surface of the most heelwardly disposed element, in the plane of its work-engaging surface. Associated with each pair of wiping elements is a clamp pad, said pad being caused clampingly to engage the shoe, while the inwiping movement of the elements continues, by operation of a common piston-and-cylinder arrangement.
A shoe machine for use in the lasting of side portions of shoe uppers, said machine comprising;
A shoe machine for use in lasting the side portions of shoe uppers as recited in claim wherein each wiping element is mounted on an arm itself mounted for pivotal movement, independently of the arm adjacent thereto, about a third axis, which third axis extends lengthwise of the last bottom, whereby the wiping element is capable of heightwise movement bodily towards and away from the last bottom.
