Abstract
A method and apparatus for straightening fibres in a sliver comprises subjecting the sliver to sliding frictional contact with a foraminous surface through which an airflow passes, the sliding contact having the effect of both straightening the fibres in the sliver to orientate them, and straightening the hooked ends of any fibres in the sliver, and the influence of the airflow serving to remove dust and/or trash from the sliver.
