<p>In a pulling over and lasting machine in addition to a toe pincer (18) there are provided two sets of side pincers (20), each set being mounted on a support (26) pivotal about an axis (24) extending heightwise of the shoe bottom and passing through or adjacent the toe pincer (18). Each pincer (20) is adjustably mounted on its support (261 but in addition each set is movable bodily, through its support, about its axis (24). In one embodiment the supports (26) are movable only in op- pos<Sup>i</Sup>te directions, i.e. towards and away from one another, thus to accommodate to shoes of different widths. In a second embodiment, on the other hand, in addition these supports (26) are also movable in the same direction, thus to cause the pincers (20) to be accommodated to left and right shoes.</p><p>For clamping the shoe at its heel end, a heel rest (12) is provided the transverse position of which is dictated solely by the heel end of the shoe without applying to the shoe any significant forces tending to re-orient it, this being achieved by allowing free movement with low friction transversely of the longitudinal centreline (L).</p> |
