Abstract

PURPOSE:To make a crosshead of the subject which can extrude to form an outer cover of high quality efficiently by laminating plural flow passage forming blocks at the mouth of a die to form a flow passage and fitting sub-nipples inside a nipple. CONSTITUTION:Plural flow passage forming blocks 3 are laminated fitting on plural studs 11 which project from the end surface of the outlet 2 of the die 1 of a crosshead and form a flow passage of a circular cross-section and a tapered form which connects with the outlet of the die 1, in the center of the blocks 3. Inside a nipple 5, the first sub-nipple 5A is fitted coaxially projecting the outlet end of the nipple 5A a little from the outlet end of the nipple 5. Inside the nipple 5A, the second sub-nipple 5B is fitted coaxially projecting the outlet end of the nipple 5B a little from the outlet end of the nipple 5A.
