Abstract (en)
[origin: JPS6430673A] PURPOSE: To enable the rapid adaptation to various layer thicknesses and viscosities of an adhesive by arranging a doctor blade which is built into an applicator nozzle and is easily removable and exchangeable by means of a clamp support in a slit-like discharge port. CONSTITUTION: Since an applicator head has a valve means, the hot melt discharged from the applicator nozzle 10 arranged in the bottom of the head is applied by as much as the exactly regulated amt. onto a web 32 moving forward under the nozzle 10. The hole 18 of one 12 of parallel plates 12, 14 of the nozzle 10 is connected via a passage 20 to a spreading chamber 22 where the coating thickness and width are regulated by a mask 24 consisting of spring sleet disposed between both plates 12 and 14. The clamp plate 28 presses the doctor blade 26 to the mask 24 via a clamp screw 30, the doctor blade 26 is thus easily removed and exchanged.
