Abstract

Dispositif destiné à l'alimentation en matière plastique expansible du moule d'un appareil automatique de moulage de plastique expansible. La matière plastique utilisée est du polyéthylène qui est d'abord introduit dans un silo sous pression 10 destiné à l'alimentation de moules simples ou multiples 1, 2, puis qui est envoyé sous pression dans un moule 1, 2 à l'aide de l'air comprimé introduit dans le silo et en passant par une conduite sous pression 17.Device for feeding expandable plastic material to the mold of an automatic expandable plastic molding apparatus. The plastic material used is polyethylene which is first introduced into a pressurized silo 10 intended for supplying single or multiple molds 1, 2, then which is sent under pressure into a mold 1, 2 using compressed air introduced into the silo and passing through a pressure pipe 17.
