MESH FILTER AND CABLE INSULATOR EXTRUSION PROCESS USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a mesh filter which is used for extruding a resin composition and by which problems with respect to a finer screen mesh can be solved and also any foreign matter having larger size than the opening size of such a screen mesh can be prevented from passing through the screen mesh. SOLUTION: In this cable insulator extrusion process, this mesh filter having a laminated structure formed by closely sticking a plurality of sheets of screen meshes each of which has a fine mesh structure, to each other, is used, wherein the plurality of sheets of screen meshes are laminated to each other in such a state that the direction of weaving of each of the plurality of sheets of screen meshes is different from those of the others.
