Abstract

Moulding appts. has >=2 heat conducting moulds mounted on opposite sides of a common oscillating shaft by rotating shafts placed perpendicularly to the oscillating shaft, and connected to follow the oscillations of this shaft, and to rotate in both directions together with the moulds, while adjustable and controllable heaters and coolers are situated in the vicinity of the moulds.
