An apparatus for disintegrating bulks of wastepaper into individual fibers and for removing contaminants from the fibers comprises a series of high-pressure water jets and a series of endless revolving screens of different mesh sizes. The high-pressure jets for disintegrating the wastepaper are positioned above the upper parts of the screens. The screens are configured in such a way that the screens of finer mesh sizes are located below those of larger mesh sizes with the coarsest screen at the top and the finest screen at the bottom. The apparatus combination has means to screen and wash the disintegrated fibers, and remove contaminants from the usable fibers.
