Abstract

PURPOSE:To save energy consumed by extruders by a construction wherein a heat absorption portion of a heat conduction loop is provided on the extruding side of a cylinder for a meet extruder, a heat radiation portion of the loop is provided on the hopper side, and further a special opening and closing member is provided in the heat conducting loop. CONSTITUTION:In a melt extruder for resin, a heat absorption portion 20 is provided on the extruding side of a cylinder 9, for example, on the outer wall of a barrel 8, while a heat radiation portion 21 is provided within a resin hopper 1. Both portions 20 and 22 are connected through communication paths 22, 23, within which an operating fluid such as water or flon is enclosed, thereby to constitute a heat conducting loop. Then, in the communication paths 22, 23 an opening and closing member 24 valve thereof is opened when resin in the cylinder is under normal extrusion and also when the barrel 8 is required to be cooled is provided.
