Abstract
Methods for the concentration of a dilute material such as a fiber suspension are disclosed including enclosing the dilute material between a first straining belt and a second straining belt both moving through endless paths, and in which the width of the first straining belt is greater than the width of the second straining belt, and the method includes causing the longitudinal edges of the first straining belt to overlap the longitudinal edges of the second straining belt in an initial concentration stage, unfolding the longitudinal edges of the first straining belt and then further compressing the concentrated layer produced against the first straining belt in a further concentration stage. Apparatus for carrying out this method is also disclosed.
