In the lip of the slot die/di for the coating and the slot die/di for the coating and opening measuring method of the coating roll and the both sides end

摘要

PROBLEM TO BE SOLVED: To measure a gap between lip rolls with high precision to set the same with high precision in order to manufacture a coated film of high precision.;SOLUTION: Measuring instrument attaching blocks 28 and 29 having flat block fronts 28A and 29A, the surfaces of which are flush with the lip front 21A of the leading end of the coating slot die 20, are attached to both side end parts of the coating slot die 20, and displacement measuring instruments 28 and 29 are attached to the measuring instrument attaching blocks 28 and 29. The surface 50A of a block gauge 50 is pressed to the block fronts 28A and 29A to be measured by the displacement measuring instruments 28 and 29 to perform calibration and, after the completion of calibration, the block gauge 50 is removed while a coating head is forwardly moved toward the coating roll and the gap between the lip 21 of the shot die 20 and the outer peripheral surface 11A of the coating roll is measured on the basis of the measured values of the displacement measuring instruments 28 and 29.;COPYRIGHT: (C)2006,JPO&NCIPI
