Abstract

PURPOSE:To permit to switch the resin flow path by only turning a selector plug into the circumferential direction thereof by a method wherein a starting point and a terminal point of a resin flow path are provided at positions, which are displaced from respective starting and terminal points of another set of resin flow path by a given angle in the same height, so as to be turnable into circumferential direction thereof, in the column type plug, inserted into and attached to a feed block connecting a plurality of extruding machines and molds for co-extrusion. CONSTITUTION:The starting point and terminal point of different sets of resin flow paths are provided in the same height under being displaced by a given angle. The column type plug 2, having resin flow paths consisting of a groove 7a, running along the side surface of the plug by 1/4 turns obliquely, the groove 7c, running along the same by 1/4 turns horizontally, and a hole 7b, penetrating the plug obliquely, is manu factured. When the resin flow path is to be switched, the column type plug 2 is turned clockwise by the given angle, whereby a plurality of extruding machines 3, 4, 5 are connected to the molds for co-extrusion through another set of resin flow paths, which is different from the set of paths before turning. According to this method, the resin flow path may be changed without removing a selector block from the feed block 1 to exchange it.
