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.
