Abstract
Die Erfindung betrifft eine Antriebsrolle für eine Fadenliefervorrichtung, insbesondere an Rundstrickmaschinen. Die Antriebsrolle besteht aus einer drehbar gelagerten ersten Schreibe (21), einer zu dieser koaxialen und relativ zu ihr verdrehbaren zweiten Scheibe (22) und zwischen den beiden Scheiben (21,22) angeordneten, den Umfang der Antriebsrolle (16) bildenden Gleitstücken (25), die durch die Scheiben (21, 22) so geführt sind, daß durch relative Drehung der beiden Scheiben (21, 22) eine Vergrößerung oder Verkleinerung des Durchmessers des Umfangs herbeigeführt wird. Eine Einstelleinrichtung (31), die eine relative Verdrehung der beiden Scheiben (21, 22) bei kontinuierlicher Drehung der Antriebsrolle (16) ermöglicht, enthält erfindungsgemäß ein Summengetriebe, das ein mit der ersten Scheibe (21) gekoppeltes Antriebsteil (36), ein mit der zweiten Scheibe (22) gekoppeltes Abtriebsteil (38) und ein Einstellelement (49) aufweist. The invention relates to a drive roller for a thread delivery device, in particular on circular knitting machines. The drive roller consists of a rotatably mounted first disc (21), a second disc (22) coaxial with it and rotatable relative to it, and between the two discs (21, 22), which form the circumference of the drive roller (16) and form sliders (25 ), which are guided through the disks (21, 22) so that an increase or decrease in the diameter of the circumference is brought about by relative rotation of the two disks (21, 22). According to the invention, an adjusting device (31), which enables the two disks (21, 22) to rotate relative to one another while the drive roller (16) rotates continuously, contains a summation gear which has a drive part (36) coupled to the first disk (21) the second disc (22) has a coupled output part (38) and an adjusting element (49).
