Patent ES-461689-A1 (ES)
Title: Thread delivery device for textile machines
IPC: D04B15/48
Filed: 1977-08-17
Abstract: A thread delivery device including a rotatable thread drum on which a thread is wound tangentially to form an intermediate thread storage and from which the thread is withdrawn endwise over a withdrawal edge for supply to a textile machine. A thread control element is arranged in the area of the withdrawal edge for engaging the withdrawn thread. A stationary withdrawal eyelet engages the withdrawn thread downstream of the thread control element. The thread control element is constructed as an eyelet which is closed at least opposite the direction of the rotation of the off-running thread relative to the drum. This thread control element is arranged approximately at the height of the withdrawal edge and is mounted on an arm which is rotatably supported on the drum about the longitudinal axis thereof. The friction in the rotatable bearing between the arm and the drum is of a magnitude such that the arm rotates with the drum only when the tension in the withdrawn thread falls below a desired magnitude. So long as the tension equals said desired magnitude, this tension is sufficient to overcome the friction so that the drum rotates relative to the arm, and the arm is held against a stop which limits the rotative movement of the thread control element in a direction opposite to the normal drum rotation.
