  • Patent number: 4107908
    Abstract: A method of manufacturing spun yarn comprises feeding at least one filament onto a rotating member in a manner to form flat loops of the filaments on the member, picking the loops off the member and feeding and twisting the loops to form a spun yarn. The device advantageously includes a spinning head which rotates about a longitudinal axis and which carries a disc member which rotates about its own central axis. A thread guiding device is arranged to rotate about the longitudinal axis of the spinning head and separate drives are provided for each of the spinning head, the disc and the thread guide in order to form variations in the flat loops which are formed as segmental partly overlapped loops on the disc member. The construction includes a pickup member for picking up the loops off the disc and conveying rollers for conveying the twisted yarn into a setting chamber and a force twisting device for subsequent winding on a bobbin.
