COATING HOPPER AND SEALING METHOD AT SUPPLYING SLURRY

摘要

PROBLEM TO BE SOLVED: To prolong the service life of a rubber made seal by supplying slurry only to the upper end surface without depositing on the side surface of a work. SOLUTION: This coating hopper is provided with a hopper main body 2 for supplying the slurry to the upper end surface Wu of a honeycomb carrier W and a rubber made circular seal 3 and the peripheral length of the circular seal 3 is set shorter than the upper end peripheral length of the honeycomb carrier W and the circular seal 3 is brought into press-contact with the outer peripheral surface Ws of the upper end part of the honeycomb carrier W only with the elasticity of its own.
