Abstract
For accurately positioning a shoe upper on its last preliminarily to a pulling over and toe lasting operation, the machine comprises an optical scanning system (20) by which, in cooperation with a central processor unit (22), coordinate axis values can be determined for selected portions of the topline region of the shoe upper (the 'actual' values) and be compared with a set of taught data relevant to the shoe style, such taught data representing the positions in which the selected portions of the topline region of the shoe upper are to be located (the 'should be' values), the central processor unit (22) comparing the actual and 'should be' values and supplying correction signals to motors (16) associated one with each of the pincers (10, 12) whereby the shoe upper is selectively tensioned in order to achieve the desired location of the topline region of the shoe upper on its last.
