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.

A measuring roller for a device for measuring a fiber composite (), in particular on a draw frame, a carding engine or a comber, is made of a material of low thermal expansion () and has a surface coating (). The measuring roller () features a shell surface () for clamping a fiber composite () along with a rotary axis (). The shell surface () features a structure forming an air buffer, made of grooves (), boreholes (), and/or spherical projections ().

Measuring roller and device for measuring a fiber composite

The invention concerns an apparatus for the optimization of the regulation adjustment of a machine in spinning preparation, in particular a regulated draw frame, a carding machine, or a combing machine, to which one or more fiber bands are continually fed. The apparatus has at least one sensor which is positioned ahead of the feed end of a draw frame machine for the purpose of capturing the values of band thicknesses of one or more of the entering fiber bands. The apparatus also has at least one delivery end sensor located at the delivery end of the draw frame machine for the purpose of capturing the values of the band thickness of the produced fiber band of a first draw frame operational mode. The apparatus also includes a microprocessor for the comparing of the captured values of the at least one delivery end sensor to those of at least a second draw frame operational mode, whereby the second draw frame operational mode does not represent the normal operational mode of the draw frame machine. The apparatus also includes a control and/or regulation unit for the adaption of the regulatory adjustments on the grounds of such machine characteristics and/or fiber material properties as can influence the measured values. Likewise, a corresponding procedure is proposed.
