Abstract

A method is provided for producing a yarn from at least two individual yarn components having different physical characteristics so that the produced yarn has a desired visual effect. The method includes continuously supplying at least one yarn component in the form of a bundle of continuous filaments and individually treating the bundle of continuous filaments in a treating stage. The treated bundle of continuous filaments is then conveyed to a collective compacting stage. At least one other yarn component is supplied from a spinning beam or a bobbin directly to the collecting compacting stage and the bundle of continuous filaments and at least one other yarn component are compacted collectively in a collective compacting device.
