ABSTRACT:
A sliver guide has a restrictor and deflectors for imposing uniform transverse forces on a sliver immediately before the latter is supplied to a feed roller in an open-end spinning unit, thereby spreading the sliver and loosening the core thereof. The sliver guide serves to prevent grain variations and neps that are otherwise caused in the spun yarn by the hard core and twists of the sliver which naturally form as the latter is being produced.
