ABSTRACT:
Objects in long lengths such as strip, wire, rod, sections or fibres which have been surface treated in a preceding step are, according to the present invention, liberated from entrained surface treating agent or agents by a method for stripping off said agent or agents, washing and drying said objects, said method being performed continuously and the individual steps viz. the stripping off, the washing and the drying taking place sequentially against the feeding direction of the object in question. Also an apparatus for performing the method is described. The apparatus includes a fluid inlet assembly and a fluid discharge assembly, there being a passage through said assemblies through which the object can pass in an object-feeding direction. Liquid is discharged through a jet nozzle, which surrounds the object, in an opposite direction. The liquid is recirculated, and can be transferred to a station which is prior in treatment.
