Abstract (en)
[origin: WO2008055571A1] A yarn feeding device F comprises at least one electro-optical yarn sensor S having at least one combination of a light source E and a physically closely adjacent receiver R. In the light path between the light source/receiver combination and a reflective scanning zone 12 on a storage body of the yarn feeding device a transparent optical spreading body B is provided which spreads a substantially round light spot 17 into a longitudinal light strip in the reflective yarn scanning zone 12, the transparent spreading body B being arranged such that the longitudinal axis of the light strip is oriented substantially parallel to the axes of the windings of a yarn Y carried by the storage body periphery.
