Abstract

The flotation apparatus according to the invention has a container 1 into which vortex channels 5 lead, through which the fibrous stock suspension is supplied and which advantageously have at least one step-like widening 7, 8, into which an air line 12 opens for the supply of flotation air. The container 1 is cylindrical with a vertical axis A and, in the upper region, has a pipe 13 arranged on the container axis to extract the flotation foam. In addition, a pipe 16 for the extraction of the good material is arranged tangentially, expediently in the lower region of the container 1. <IMAGE>
