Abstract
A plurality of combing machine slivers having periodically variable densities are combined in such a way that the density variations approximately compensate one another and a complete sliver having little density variation is formed. The relative phase positions of the respective combing machine slivers when assembled together are controlled in response to the periodicity of the complete sliver.
