PROBLEM TO BE SOLVED: To provide a rubber sheet molding machine having an I-header which can be sharply reduced in weight in spite of its structure capable of enduring internal pressure at the time of extrusion of a rubber material and can be made simple and efficient to a great extent in cleaning work for removing the residual rubber material in the header. SOLUTION: This rubber sheet extrusion molding machine is equipped with the I-header which is constituted of a pipe-shaped outer cylinder strong enough to endure the internal pressure at the time of extrusion of the rubber material and the pipe-shaped inner cylinder which is inserted in the outer cylinder in parallel and can be pulled out of the outer cylinder. The inner cylinder can be divided into at least two parts along the longitudinal line when it is pulled out of the outer cylinder. COPYRIGHT: (C)2004,JPO&NCIPI |
