Abstract
A yarn twisting and winding apparatus is disclosed which is adapted to produce a yarn ball, and which includes a yarn support spindle (12) and surrounding flyer (19). The flyer is rotatable about a central axis (15), and the yarn support spindle is mounted so that its axis (12') intersects the central axis. Also, the spindle (12) is rotated about the central axis (15), as well as its own axis (12') during the winding operation. A yarn delivery roll (4) is mounted coaxially about the central axis, and so that the yarn is adapted to advance to the flyer, around the yarn delivery roll, back to the flyer, and then to the yarn support spindle to form a yarn ball.
Claims22
A yarn twisting and winding apparatus adapted to produce a yarn ball, and which includes yarn takeup means comprising a yarn support spindle (12) which defines a spindle axis (12'), a yarn twisting flyer (19) mounted for rotation about said yarn support spindle and so as to define a central axis (15), and flyer drive means (2,3,5) for rotating said flyer about said central axis, characterized in that said yarn takeup means includes means (7,8) mounting said yarn support spindle such that said spindle axis is angularly disposed with respect to said central axis and such that said yarn support spindle is rotatable about both said central axis and said spindle axis, and drive transmission means (20,21,29) operatively connected to said flyer drive means for concurrently rotating said yarn support spindle about said central axis and said spindle axis.
