ABSTRACT:
A machine for making a composite article including a sheet material blank and an injection moulding thereon, comprises first and second cavity tools which are relatively movable between open and closed conditions and in the latter define a cavity, and a core tool movable relative to the cavity tools between open and closed conditions in the latter of which the core tool and first cavity tool together define a blank receiving cavity and the core and first and second cavity tools together define a mould cavity, the second cavity tool lying between the first cavity tool and the core tool when the tools are in open condition and supporting guide means for guiding a blank falling under gravity from a blank magazine to a position in the path of relative movement tools and between the core tool and the second cavity tool when the tools are in open condition, stop means on the core tool extending into the guide means to support a blank therein above the tools when the tools are in closed condition and to permit the blank to fall to its position in the tool path when the tools move to the open condition.
