Abstract
A sliver guide for guiding a plurality of textile slivers in an entry region of a drawing frame, includes a first guide portion for guiding a first group of textile slivers, and a second guide portion for separately guiding a second group of textile slivers. In a side view of the sliver guide, the first guide portion and the second guide portion are spaced apart from one another. The sliver guide has a third guide portion spaced apart from the first guide portion and from the second guide portion. To at least one of the guide portions, lateral guide elements for laterally guiding textile slivers are assigned, wherein the mutual distance of the guide elements can be adjusted.
