Abstract
In order to produce a fancy yarn with protuberances along its length in a simple manner, and without adding either a binding yarn or an effect yarn, a multi-filament yarn of continuous filaments is forwarded by a positive drive means and twisted and taken up by a spindle. When engaged with a surface of the drive means the yarn is engaged by an edge which brakes some of the filaments.
