DEVICE FOR COATING HOT MELT ADHESIVE TO BASE MATERIAL RUNNING TOP FACE OF COATING LINE

摘要

PROBLEM TO BE SOLVED: To stably and surely land a fibrous bead of a sprayed hot melt adhesive on a base material.SOLUTION: A plurality of slit air ports 1 having cross-sectional shapes of thin rectangular shapes and being rectangular in the running direction of a coating line and in a crossing direction are formed so as to face each other with a plurality of hot melt adhesive holes 11 at the front running side and rear running side of the coating line of a nozzle head 10 so that slit air whose cross-sectional shape is thin rectangular is blown from the nozzle head 10 having the hot melt adhesive holes 11 and pressurized air holes 12 to the front running side and rear running side of the coating line.
