Abstract
A thread guide (33) for traversing and guiding a thread (5) in a rotating winding bobbin (1) for producing a cross-wound bobbin in a bobbin winder of a textile machine by controlling vibrations of the thread guide. The thread guide (33) is permanently and directly connected to at least one energy accumulator (20,21) throughout the entire traversing motion. The potential energy of the energy accumulator (20,21) increases continuously after the dead center of the traversing area. A substantially harmonious oscillating mechanical system is thus formed with the thread guide.
Claims16
A yarn guide for the traversing feeding of yarn to a rotatingly driven winding bobbin for producing a cheese in a winding head of a textile machine, wherein the yarn guide has a yarn guide finger and is pivotable around an axis, which is oriented essentially vertically in respect to the bobbin axis, wherein the yarn guide has an electromechanical drive mechanism, which imparts the torque necessary for generating a predeterminable oscillation to the system in a defined manner, and wherein at least one mechanical energy storage device is permanently coupled during the entire traversing movement with the yarn guide for aiding the reversal of the direction of movement,
- characterized in that
- the yarn guide (33) is directly connected with the at least one mechanical energy storage device (20, 21, 30, 31), whose potential energy continuously increases in the direction toward the dead points of the traversed area and which, because of this, constitutes an essentially harmoniously oscillating mechanical system together with the yarn guide (33).
