Abstract (en)
[origin: EP0214929A2] The intermeshing cams hold the staple fibre material in a wave-like shape. The wave-like position of the fibres permits a very orderly drafting process, the order parameter corresponding to the advantageous fibre position in the sliver multiplied by the degree of draft. The proportion of thick and thin places is greatly reduced, since the entrainment of short fibres by long fibres is prevented. <IMAGE>
