Abstract
A coater for dispersed slurry capable of coating coated dispersed slurry on a nonwoven cloth-like base material while bringing the slurry into contact with the material, comprising a net conveyor for transferring the nonwoven cloth-like base material, a supply means for supplying the dispersed slurry onto the net conveyor, and a coating roll for forming a coating layer of a specified thickness by pressing, from the upper side thereof, the dispersed slurry supplied onto the nonwoven cloth-like base material, wherein this coating roll is allowed to come into direct contact with the dispersed slurry on the peripheral surface of the nonwoven cloth-like base material or allowed to come into contact with the dispersed slurry through a film provided therethrough.
Claims16
A coater for coating a nonwoven fabric substrate with a dispersion slurry where a solid component is dispersed in a dispersion medium, said coater comprising:
- a means for running said nonwoven fabric substrate continuously in a horizontal direction,
- a coating roll rotating in a positive direction with respect to the running direction of said nonwoven fabric substrate, and
- a cover film covering the peripheral surface of said coating roll in a range from the vicinity of a top end of said coating roll to the vicinity of a bottom end of said coating roll,
- a head bath opened at its top portion located above said running nonwoven fabric substrate, said head bath having a vertically adjustable rear gate located on an upstream side of said head bath and forming a bath for storing said dispersion slurry between said rear gate and said cover film on a top surface of said nonwoven fabric substrate,
- a liquid sealing plate located underneath of said head bath for sealing said head bath so that said dispersion slurry may not leak from a bottom surface of said nonwoven fabric substrate,
- wherein said dispersion slurry is supplied to a region between a front end of said cover film and the top surface of said nonwoven fabric substrate;
- said coating roll is constituted in such a manner that said coating roll adjusts a pressure to said nonwoven fabric substrate and the dispersion slurry applied to the surface of said coating roll to produce a smooth coated surface with said dispersion slurry.
