ABSTRACT:
An inverter device is intended to operate on half-moulds which advance in alternate sequence on a conveyor line. The inverter device has inverter sets on both sides of the conveyor line, each of which comprises a fixed unit and a movable unit with respective engagement formations capable of engaging the half-moulds by the effect of a general approaching movement towards the conveyor line. Having achieved engagement of the half-moulds the movable unit is then driven to rotate by means of a mechanism actuated by a cam so as to obtain the desired inverting movement. The same configuration can be utilised equally well for causing book-like mould closure movement of adjacent half-moulds as for causing mould-opening motion of superimposed half-moulds.
