摘要：
A feeding and opening device for open-end spinning units comprises a feeding roller and a feed table resiliently urged against the feeding roller for feeding a sliver to an opening roller, as well as at least one mechanical supporting element that is located at a spacing from a guide edge of the feed table, while leaving a free space that is open towards the atmosphere between the guide edge and the at least one mechanical supporting element. In accordance with preferred embodiments, the supporting element may be formed of at least one strip located essentially in parallel to an axis of rotation of the opening roller, or at least one row of needles arranged with their free ends directed towards the opening roller.
