Abstract
The present invention relates to a process for making a core spun yarn, wherein elementary fibres are projected onto a yarn, the yarn being subjected to the action of a false twist spindle. The projection of the fibres is obtained by means of a mobile guiding surface on which the fibres are delivered tangentially and are maintained paralleled and flat. Furthermore, the core is delivered tangentially on the paralleled fibres obliquely and in the direction of displacement of said fibres. The invention also relates to a device for carrying out this process.
