Abstract

An array of first mould parts 38 are releasably retained in a first retaining means 40, with an array of second mould parts releasably retained in a second retaining means 20. The two retaining means are bought together so as to bring the arrays of each mould part together whilst grippers 32 grip the first mould to maintain alignment. The assembled retainers can now be moved around together, without causing misalignment in the moulds. Also disclosed is a mould heating arrangement using multi point (72,fig.9) heat resistant wires to spread heat around a mould arrangement such as that already described.
