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.

Process and device for producing fancy yarn

The invention relates to fancy yarns, and a method of making them, in which at least two yarns, of which one forms a core and one an effect yarn, are fed to a junction point and then fed together through a heat treatment zone and assembled into the fancy yarn in a false twisting step, the core yarn having been provided with a thermoplastic binder upstream of the junction point by which the effect yarn is adhered to the core yarn.
