<p>A machine (1) for the preassembly and assembly of an upper (2) on a shoe-making last (3) comprises a bearing structure (9) with which are associated: a support (4) on which to position last (3) along a longitudinal axis (L-L), a central gripper (5) positioned in alignment with the front part of the last (3) and first and second opposing pluralities of lateral grippers (10, 11). Wherein the lateral grippers (10, 11) are associated with a respective support member (13, 14), movable relative to the bearing structure (9) on a curved trajectory (T) encompassing said support means (4). Advantageously, the support members (13, 14) are mounted on respective trolleys (20, 21) which can move from and to a remote position in which the respective pluralities of lateral grippers (10, 11) are at a distance from the central gripper (5), so as to create a sufficient space to manipulate a tool around the central gripper (5).</p> |
