Abstract (en)

[origin: US4698962A] When producing fancy yarn on open-end spinning devices, sliver-like basic fiber material is opened into individual fibers and is fed in an air stream to an open-end spinning element. A fiber sliver of the fancy-effect fiber material is conveyed at constant speed into an air stream by which fiber tufts are separated. Fancy-effect fiber tufts and individual fibers thus separated are fed to an open-end spinning element together with the opened basic fiber material. To carry out this process, a feeding device is provided for the fancy-effect fiber material, such feeding device being driven at constant speed so that the fancy-effect fiber material is brought into the fiber feeding channel in the form of an uninterrupted fiber sliver.
