ABSTRACT:
In a side (or side and seat) lasting machine two side lasting assemblies (230) are provided each comprising a side lasting roll (276) having a helical wiper element (282). As the rolls (276) are caused to operate progressively along opposite side portions of the shoe bottom from the heel breast line region toewardly, they are caused to rotate thus effecting an inwiping action on the lasting margin and pressing it against the insole margin. At a predetermined point in such progressive operation, at least one of the rolls (276) is displaced axially inwardly towards one another to enhance the inwiping action. This axial displacement may take place at the ball region of the shoe bottom, i.e. at or just before the end of the operation, and only the "outside" roll (276) or both rolls (276) may be so displaced. Alternatively the "outside" roll (276) may be displaced when it has reached the waist region, and in addition, if desired, the "inside" roll (276) in such circumstances is displaced axially inwardly at the start of the lasting operation.
