Abstract
In the case of an apparatus for a sliver-forming textile machine, especially a draw frame, flat card or the like, a fiber structure (fiber web) coming from the delivery rollers of a drafting system passes through a web guide and a sliver funnel with take-off rollers, the web guide has an inner wall (deflection and/or guide face), and a frictional resistance offered by the inner wall acts on the fiber structure. In order to allow in a simple manner an improved web guidance and sliver quality, and to permit the web guide to be adapted to different technical parameters, such as fiber material properties, working speed, a parameter relating to contact between fiber structure and inner wall is alterable.
