<p>PURPOSE:To constitute a network structure mat molding being in contact with each other at a constant distance by limiting such that each nozzle being disposed in a rank on the T-die of an extrusion molding machine is swingable with respect to the extrusion face of a molding material, and the swinging face to an adjacent nozzle conducts a counter periodical motion. CONSTITUTION:Each nozzle 1a, 1b...1n being disposed in a rank (about 54-90pieces) to the main body of a T-die is constituted to be swingable with respect to their molding extrusion faces, and limited such that the swinging faces of the nozzle 1a, 1b...1n adjacent to each other are in opposite directions. Herein, each streak-shaped molding extruded from each nozzle winds such as waves, and forms a continuous length molding in succession. And, by accelerating the transporting speed of a conveyor transporting a network molding with respect to the extruding speed of streak-shaped moldings, there may arise the tensile operational force of the extrusion face to the meandering form moldings, and patterns can be thus be deformed thereby.</p> |
