Abstract
This invention relates to equipment for producing partially expanded bodies with a cell structure based on PVC and R-NCO. This includes a plurality of moulds 3 of predetermined height filled to an excess by weight of approximately 8% with a paste 3 comprising PVC and other substances, the said moulds 2 being loaded into a press 1 and located between heating and cooling plates 5 so that through the action of pressure and the change in temperature paste 3 gives rise to partly expanded bodies. The equipment is characterized in that the moulds 2 are provided at approximately half their height with at least one hole 9 for extraction of the surplus paste 3. This extraction takes place a predetermined time after the start of heating so that the paste 3 removed does not have a temperature of more than approximately 40 degree C.
