Abstract (en)
The apparatus comprises a housing (10) defining a treatment vessel (12<2>) having entrance and exit openings (16, 20) defining a sheet material path (22) therethrough. The lower opening (20) is closed by a pair of path-defining rollers (28, 26) biased into contact with each other to form a nip (28) through which the sheet material path (22) extends. The housing (10) includes a collecting chamber (50) positioned to collect treatment liquid which in use falls from the treatment vessel (12<2>) through one or both of the openings. The collecting chamber (50) is a closed chamber (50) and means (52) are provided to return treatment liquid from the collecting chamber (50) to the treatment vessel (12<2>). The construction has the advantage that the wastage of treatment liquid is reduced without requiring the use of complicated and costly sealing devices. <IMAGE>
