Abstract
A textile sliver is fed through a tube and into a drum to coil therein, and the tube and drum are relatively rotated about an axis; the tube extends at an angle to the axis to deliver the sliver to coil within the drum; the sliver has a static charge as it enters the tube, and the method includes the steps: A. imparting to the tube inner wall a static charge of a polarity the same as said charge on the sliver thereby to effect a repulsion of the sliver from said inner wall, and B. continuing said feeding of the sliver through said tube as the tube rotates about said axis.
Claims5
In the method of feeding a textile sliver into a drum to coil therein, and wherein the sliver is fed through a tube, the tube and drum relatively rotated about an axis, the tube extending at an angle to said axis to deliver the sliver to coil within the drum, the sliver entering the tube having a static electrical charge of determinable polarity, said method including the steps
- a. imparting to the tube inner wall a sufficient static charge of a polarity the same as said charge on the sliver thereby to effect a repulsion of the sliver from said inner wall as the sliver travels completely through the tube, and
- b. continuing said feeding of the sliver through said tube as the tube rotates about said axis.
In apparatus for feeding a textile sliver into a drum to coil therein, and including a tube, the tube and drum relatively rotating about an axis, the tube extending at an angle to said axis to deliver the sliver for coiling in the drum, the sliver entering the tube having a static electrical charge of determinable polarity, the improvement which comprises,
- a. means for imparting to the tube inner wall a static charge of a polarity the same as said charge on the sliver, thereby to effect a repulsion of the sliver from said inner wall as the sliver travels through the tube,
- b. said axis extending generally vertically and generally coaxially with the drum and said tube rotating, about said axis and relative to the drum, and
- c. said means including a conductive ring on the tube near the upper end thereof to rotate with the tube, a conductive follower engaging said ring, and a source of voltage of said polarity electrically connected with said follower.
