ABSTRACT:
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.
