COATING DEVICE OF TWO-LIQUID CURABLE SOLVENTLESS ADHESIVE

摘要

PROBLEM TO BE SOLVED: To suppress the variation of the component ratio of a two-liquid curable solventless adhesive and thickness variation.SOLUTION: A coating device 1 where a two-liquid curable solventless adhesive is transcribed with a plurality of rolls and applied onto a web W and an application roll 20 and a doctor roll 21 are disposed side by side in a butting state at minute gap intervals includes: a mixer 11 making an adhesion mixed liquid by mixing two component liquids; a pair of weir plates 22 forming a liquid reservoir part storing the adhesion mixed liquid in the upper space of a minute gap; and a nozzle 12 supplying the adhesion mixed liquid to the liquid reservoir part. The rotation of the application roll 20 is controlled to be a super low speed of 1 rpm or less.SELECTED DRAWING: Figure 1
