<p>PURPOSE:To satisfactorily draw by always suitably maintaining a grasping force of drawing means for an extrusion molded form even if a lateral sectional shape of the form is varied by altering the force of the means for the form corresponding to an alteration in the sectional shape of the form. CONSTITUTION:An upper mold 2A having a low height size from an extrusion mold 6 is extruded as a molded form. An interval beta of caterpillars 12a, 12b of a drawing machine 12 of the mold 2A is set to a minimum beta0. Thus, since the interval beta of the caterpillars 12a, 12b of the machine 12 is regulated corresponding to the height of the mold, a grasping force of the machine 12 for the mold is suitably maintained, and the mold is satisfactorily transferred by the machine 12. The moving of the machine 12 is controlled in cooperation with the operating timing of a cutter 17 according to an operation signal S13 to be output from a controller 14.</p> |
