Abstract
A method and a device for winding a spun yarn body from an inside wall of a spinning centrifuge of a pot spinning machine onto a tube (10) introduced for such purpose into the spinning centrifuge. The yarn extending between a yarn guide tube (6) and the inside wall of the spinning centrifuge is caught by lowering the tube past the mouth of the yarn guide tube and the winding process initiated. A remnant of spinning yarn is created thereby between the draw frame and the tube foot. In order to avoid disturbances due to the free end of this remnant of spinning yarn, the remnant of spinning yarn is separated from the yarn body and the tube and subsequently removed by suction.
Claims16
A method for winding a body of a spun yarn from an inner wall of a rotating spinning centrifuge of a pot spinning machine onto a winding tube having a slot at a foot thereof, wherein the winding tube surrounds a yarn guide tube having a leading end extending into the spinning centrifuge with a mouth at the leading end from which mouth the spun yarn travels to the inner wall of the spinning centrifuge, the method comprising:
- a) inserting the foot of the winding tube into the spinning centrifuge beyond the mouth of the yarn guide tube,
- b) catching a rotating extent of the spun yarn between the mouth of the yarn guide tube and the inner wall of the spinning centrifuge, by the slot at the foot of the winding tube to initiate winding of the body of the spun yarn onto the winding tube as the spinning centrifuge rotates and to separate from the body of the spun yarn on the winding tube near the slot at the foot of the winding tube a remnant extent of the spun yarn trailing the rotating extent thereof;
- and
- c) removing the separated trailing remnant extent of the spun yarn.
A pot spinning machine comprising:
- a) a rotating spinning centrifuge having an inner wall upon which a body of a spun yarn is formed,
- b) a yarn guide tube having a leading end extending into the rotating spinning centrifuge with a mouth at the leading end from which mouth a spun yarn travels to the inner wall of the rotating spinning centrifuge,
- c) a winding tube having a foot,
- d) a means for inserting the foot of the winding tube into the rotating spinning centrifuge beyond the mouth of the yarn guide tube,
- e) a means for catching a rotating extent of the spun yarn between the mouth of the yarn guide tube and the inner wall of the rotating spinning centrifuge, wherein the rotating extent of the spun yarn is trailed by a remnant extent of the spun yarn,
- f) at least one cutting device for separating the remnant extent of the spun yarn from the body of the spun yarn, and
- g) a means for removing the separated remnant extent of the spun yarn.
