Abstract (en)
A fibre-opening unit for an open-end spinner comprises first pre-drafting rolls (3, 4) and second pre-drafting rolls (5, 6) with a variable velocity ratio between the first and second pairs of rolls whereby the pre-draft can be changed in order to adapt the open-end spinning unit to the quality of the sliver supplied.
