Patent ID: 7410116

Claim:
A system for winding cross-wound bobbins ( 1 ) with cross windings ( 14 ) having two face ends ( 15 ) comprising a tube holder ( 2 ) rotatably supported for movement about an axis of rotation ( 3 ), a cross-wound bobbin tube ( 13 ) adapted for removable positioning onto said tube holder ( 2 ) for rotation with the tube holder; a drive mechanism ( 4 ) for rotating the tube ( 13 ) in order to wind up a yarn ( 59 ) onto the tube ( 13 ); a yarn guide element ( 5 ) mounted for movement back and forth in a longitudinal direction of the cross winding ( 14 ) and tube ( 3 ) in order to shog the yarn ( 59 ) during the winding process so as to form a cross winding ( 14 ) on the tube ( 13 ); a rodless work cylinder ( 6 ) having a cylindrical space ( 22 ) between opposed end faces with a piston ( 23 ) that divides the cylindrical space into first and second cylindrical chambers ( 24 , 25 ), one of said cylinder end faces being formed with a bore ( 72 ), a cable ( 68 , 75 ) extending through said cylinder end face bore and coupled between said piston ( 23 ) and said yarn guide element ( 5 ); a controllable fluid supply device ( 7 ) which selectively communicates with the chambers ( 24 , 25 ) in order to selectively supply fluid under pressure to at least one of the cylindrical chambers ( 24 , 25 ) or to vent at least one of the cylindrical chambers such that the piston ( 23 ) is moved with the requisite longitudinal motions for causing said cable to move said guide element ( 5 ); and a control unit ( 8 ) for controlling the fluid supply device ( 7 ) such that the piston ( 23 ) is moved with the requisite motion for the rotating tube ( 13 ) or cross winding ( 14 ) for effecting the desired movement of the yarn guide element ( 5 ) by means of the connecting cable ( 68 , 75 ).
