Abstract

In continuously treating pulp in an apparatus with a treating liquid wherein a web of cellulosic material is moved enclosed between two belts running together over rotatable rolls in a treating section while supplying liquid to the web and displacing it therefrom in at least two consecutive treating stages, it is proposed according to the invention that the belts (3, 4) and the web (14) enclosed therebetween, are moved in an upwardly running winding path (9, 10), for instance, and that in a first treating stage within this path treating liquid is supplied to the web (14) on a first surface thereof and in a second treating stage on a second surface thereof, and that in the first treating stage liquid is displaced from said second surface and in the second treating stage liquid is displaced from said first surface by compression of the web (14) between the belts (3, 4) during their movement around a first and a second guide roll (5), respectively, so that the liquid is displaced through the web (14) in direction from the envelope surface of the guide roll which in that case is solid, the web (14) acquiring a relatively high dryness content by each liquid displacing compression. The displacement of liquid at a given guide roll occurs in a flow direction through the web (14) that is opposite to the flow direction of the liquid at the immediately following or immediately preceding guide roll (5).
