Abstract
A thread-delivery device for textile machines, comprising a drum which can be driven for rotation, onto which drum can be tangentially wound a thread coming from a thread bobbin for forming an intermediate thread storage, and from which for positive delivery the thread can be removed tangentially in the area of a removal edge of the drum through a thread-guiding member which is arranged approximately at the level of the removal edge radially outside of the drum. A thread-control element is provided which is transversely movably supported relative to the withdrawn thread, which thread-control element is maintained by the withdrawn thread in one operating position in the area of the thread path between the drum and the thread-guiding member approximately at the level of the removal edge of the drum when the withdrawn thread is at normal operating tension. The thread-control element moves when the thread tension is reduced due to its weight or spring loading into a position below the plane of the removal edge. The thread-guiding member is displaceable from a first position at the level of the removal edge to a second position below the level of the removal edge, or an additional threa…
