Since the same pressure is exerted on the lateral boundaries 20 by two adjacent receiving chambers 21, the forces applied to the lateral boundaries 20 cancel each other out. For this reason, the side boundaries 20 and thus also the side boundaries 39 of the displacement bulkhead 38 can be made very thin, whereby a possible residual portion of the melt belt 14, which is not compressed, can be kept extremely low.
  • the pressure exerted by the tools 17 and 18 on the melt portions 14 can be selected depending on the moldings to be formed.
  • a special feature of the device according to the invention is that the pressure holding time, i. the time interval at which the maximum pressure is exerted on the mass to be compacted, can be individually adjusted to the mass to be deformed and tuned to this.
  • the pressure holding time can be chosen to be very long, in particular in comparison to conventional tableting machines. It is essentially determined by the rotational speed of the drive unit 2 and the length of the straight forming section A.
