Method and device for applying a softening agent to a strip of filter tow in the tobacco-processing industry

摘要

During spraying of filter material used in the tobacco-processing industry with a liquid softening agent in an application chamber (18), if conveying is interrupted, at least one of the two components of the softening agent remaining in the application chamber is removed, temporarily stored in a separate reservoir (37) and returned to the application chamber as quickly as possible, in addition to the normal supply of softening agent, when conveying is resumed, in order to ensure in this manner that a quantity of softening agent which is as clearly defined as possible is always applied to the filter material in the start-up phase of the machine as well. <IMAGE>
