Abstract

PURPOSE:To manufacture economically a reticular object which intersects on the surface by a method wherein the top part of an extrusion molded object of thermoplastic resin which gives a rugged shape to the section in the direction vertical to extrusion is cut in the direction vertical to extrusion and then stretched. CONSTITUTION:Molten thermoplastic resin is extruded from extruder 1 through extruding flat die 2 in the shape of rugged die lip. Molded object 4 obtained, at its upper part, is extruded at a desired depth between top 6 and bottom 7 and cut in the vertical direction. Hereafter, while said molded object 4 is still in a plasticized state, it is stretched continuously in an extruding direction to form a network. The molded object 4 is stretched crosswise by expansion roll 5 etc., the projected and recessed parts of the top 6 and the bottom 7 of the molded object 4 are stretched and the molded object 4 is flattened and cooled to obtain a product.
