ト口金。 In a straight die for extruding a composite tube having an intermediate layer of foamable resin between inner and outer layers made of synthetic resin, a first mandrel forms a flow of foamable resin in an annular shape at the front of the die ring 1 to form the intermediate layer. 6
is supported on the die ring 1 by the spider 7, and a crossbed die 13 for supplying resin flow constituting the outer layer is provided at the rear of the die ring 1, and three layers, an inner and outer layer and an intermediate layer, are provided at the rear of the die ring 1. The second mandrel 9 for forming the layer is moved to the first by the spider 10.
A straight pipe for manufacturing a composite pipe made of synthetic resin, which is supported by a mandrel 6 and is characterized in that a supply port 17 for a resin flow constituting an inner layer is provided at the rear of the first mandrel 6.
