Abstract: In a side (or heel seat and side) lasting machine, opposite side portions of the upper are clamped against the last, by means of clamp pads arranged in two rows one at each side of the last, prior to the lasting margin being wiped over corresponding marginal portions of the insole. To ensure that the upper lies snugly against the last prior to the in-wiping operation, the most heelwardly disposed pad of each row is so mounted that, as it is moved inwardly towards the last, it engages the upper at a position spaced from the feather line thereof, continued inward movement thereafter causing the pad to move towards the feather line, thereby causing an upward drafting of the upper. Said pads may be mounted to pivot or to be deflected to effect such upward draft. If desired, adjacent pads may be similarly mounted.

Abstract: 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.

Abstract translation: 鞋侧或组合后跟座和侧持器具有两个侧面持久组件，每个组件包括安装成独立于相邻元件枢转运动的擦拭元件围绕最后底部横向和纵向延伸的第一和第二轴。 为了提供基本上连续的擦拭表面，当所述表面水平放置时，第一轴线沿其纵向中心线位于其相关元件的工件接合表面的平面中。 而且，每个持久的组合件可以在其工作接合表面的平面内围绕邻近最跟随设置元件的工件接合表面的边缘的轴线身体枢转。 与每对擦拭元件相关联的是夹紧垫，所述垫被夹紧地与鞋接合，同时通过共同的活塞和缸体布置的操作来继续元件的推进运动。
