Abstract

Nozzle has a channel in it and devices for fixing it to the mould. At least part of the nozzle can be moved at right angles to the injection direction between a position in which the channel in the nozzle is in line with the injection channel, and position in which the mouth piece closes the injection channel. The mouthpiece or part of it can be removed from the mould.
