<p>A preforming machine for the heat bonding or cold shaping of the back-counter between the lining and the upper of shoes comprising a supporting structure (2) which supports a forming cushion (4), which provides a forming cavity (5) for the rear part of the upper (6) of a shoe and can move on command, in an actuation direction (3) which has a vertical component, from a raised standby position to a lowered working position. The machine further comprises a last (7) which is adapted to support the upper (6) of a shoe and is hinged to the supporting structure (2) about a horizontal pivoting axis (8). The last (7) is able to rotate on command about its pivoting axis (8) from a standby position, in which it is offset with respect to the forming cavity (5), to a working position, in which it is vertically aligned with the forming cavity. Actuation means (10) for the forming cushion (4) are provided in order to transfer it from its standby position to its working position and viceversa. Means (17,18) are also provided for connecting the actuation means (10) to the last for the transfer of the last (7) from its standby position to its working position or viceversa as a consequence of the activation of the actuation means (10). <IMAGE></p> |
