Abstract
A method and an apparatus for operating a process line in a spinning mill comprising various regions, for example comprising at least the regions blow room, spinning preparation and spinning, with each region being put together from several textile machines which operate in series and/or in parallel and form a machine plane, and with the individual series connected textile machines producing different fiber structures, wherein raw fiber material which enters into the blow room is obtained as spun yarn at the output of the spinning mill, is characterized in that one measures at least one quality feature of the respectively produced fiber structure at at least some textile machines in each of the named regions and uses it to regulate the respective textile machine or an earlier textile machine of the same region; and in that correction values are formed from at least some of the quality features measured in the spinning preparation and spinning regions and are used to influence the operation of a textile machine of an earlier region.
