Abstract
The invention relates to a process and device for making a spun yarn of fibres comprising an internal core which consists in subjecting the yarn to form the core to a momentary false twist by means of a spindle and projecting elementary fibres onto this yarn. Such elementary fibres are projected by means of a mobile guide surface on which the fibres are delivered tangentially, the core likewise being displaced tangentially with respect to the guide surface in a direction concurrent with the direction of delivery of the fibres.
