Abstract: A pantograph machine is provided for producing either by enlargement or reduction copies from a master model. A tracing head and cutting head move together but relatively. The cutting head moves in a rotary manner and the translation of the relative motion between the cutting head and the tracing head is variable to accommodate different contours with a minimum of damage and faithfulness of reproduction.

Abstract: The invention discloses a process of multi-material moulding using a novel material guidance device or transfer plate which also acts as a transport mechanism to guide, from one moulding station, a partially moulded component or article, along a controlled flow path, to another station and to register the said article into the requisite second cavity thereat for subsequent moulding of another mould material. The transport mechanism, on arrival at the second station, may, but need not, be stripped away from the partially moulded component contained thereon, but only after the article is disposed into the registration within a subsequent or second cavity located at the second mould station. Under the preferred embodiment, the transfer plate acts as a core member to the mould of the cavity during at least one moulding step; in its simplest form the transfer plate is flat.
