Abstract
In the yarn-delivery device having at least one friction cylinder (11, 12) and at least one pivoting arm (15, 16) for each yarn (20) to be delivered, the pivoting arms having at least one deflecting roller for the yarn are mounted pivotably outside the friction cylinder and are so curved that they are pivotable to behind a friction cylinder (11, 12) and a plurality of pivoting arms (15, 16) for separate yarns (20) can be arranged next to one another. (FIG. 1)
Claims17
A device for delivering yarn comprising:
- two driven friction cylinders each having a circumferential speed higher than a draw-off speed of said yarn;
- two curved pivoting arms, each pivoting arm being associated with said driven friction cylinders, each pivoting arm having a length which is greater than a diameter of one of said driven friction cylinders and having a pivoting axis extending outside said driven friction cylinders;
- and
- two deflecting rollers mounted on a free end of each of said curved pivoting arms for guiding said yarn off said driven friction cylinders, wherein the position of said deflecting rollers defines a looping angle of said yarn around said driven friction cylinders and said deflecting rollers being arranged at a distance from one another and having parallel axes.

A device for delivering yarn comprising:
- two driven friction cylinders each having a circumferential speed higher than a draw-off speed of said yarn, and extending at a distance from and parallel to one another;
- two curved pivoting arms, each pivoting arm associated with said driven friction cylinders, each pivoting arm having a length which is greater than a diameter of one of said driven friction cylinders and having a pivoting axis extending outside said driven friction cylinders;
- and
- two deflecting rollers mounted on a free end of each of said curved pivoting arms for guiding said yarn off said driven friction cylinders, wherein the position of said deflecting rollers defines a looping angle of said yarn around said driven friction cylinders and said deflecting rollers being pivotable into said distance between said friction cylinders.

A device for delivering yarn comprising:
- two driven friction cylinders each having a circumferential speed higher than a draw-off speed of said yarn, and having a continuous long cylinder for a plurality of yarns;
- two curved pivoting arms, each pivoting arm being associated with said driven friction cylinders, each pivoting arm having a length which is greater than a diameter of said associated driven friction cylinder and having a pivoting axis extending outside said driven friction cylinders, each yarn being assigned to said two curved pivoting arms, said curved pivoting arms being individually adjustable;
- and
- two deflecting rollers mounted on a free end of each of said curved pivoting arms for guiding said yarn off said driven friction cylinders, wherein the position of said deflecting roller defines a looping angle of said yarn around said driven friction cylinders.
