<p>The device is intended to operate on half-moulds (11, 12) which advance in alternate sequence on a conveyor line (10). The device comprises, on both sides of the conveyor line (10), inverter units (20) capable of following the movement of the line (10) itself. Each of these units (20) is provided with a fixed unit (36) and a movable unit (38) with respective engagement formations (40, 42) capable of engaging the half-moulds (11, 12) by the effect of a general approaching movement towards the line (10). Having achieved engagement of the half-moulds (11, 12) the movable member (38) is then driven to rotate by means of a mechanism actuated by a cam (64, 66) so as to obtain the desired inverting movement. The same configuration can be utilised, in an oppositely handed manner equally for book-like mould closure movement of adjacent half-moulds (11, 12) as for the mould-opening motion of superimposed half-moulds (11, 12). <IMAGE></p> |
