The invention relates to a method and an apparatus for performing the method to produce a sliver (10) of natural and synthetic fibres with a combing machine having several combing heads for processing natural fibres such as cotton, with the combing machine fleece produced in the respective combing head being joined into a sliver and the individual slivers being supplied to a subsequent drafting arrangement device in which a combing machine sliver is formed after the drafting process. Usually, the mixture of slivers is performed in subsequent drawing passages after the combing machine to obtain a mixed yarn. To obtain a sufficiently thorough mixture at least three such passages were usually required. To reduce the subsequent drawing passages and to utilise existing capacities the slivers supplied by the combing heads are mixed with slivers made of synthetic fibres prior to their entry into the main drafting zone of the drafting arrangement device.
