Abstract
A multi-position open-end spinning machine has the directions of traverse of the traverse guides of some groups of its spinning positions opposed to the simultaneous direction of traverse of the traverse guides of the spinning positions in other groups. Alternatively some traverse guides in a particular group of spinning positions may be in opposition to other traverse guides in the same group. The phase angles of the traverse guide motions may be distributed to have several different phase angles along the machine for noise reduction. The invention may also be applied to any multi-position winding machine.

Multi-position yarn handling machine including:
- (a) a plurality of yarn handling positions along the machine;
- (b) respective yarn package-forming means including a package former at each said position;
- (c) respective traverse guide means for each package-forming means for traversing the yarn across said package former;
- and
- (d) means driving the traverse guide means such that at least the majority of said traverse means execute traverse guide motions phased such that pairs of said positions which are not necessarily alongside one another but are on the same side of the machine have the traverse guide motions of their traverse means directly out of phase, wherein said pairs comprise a first pair having a first phase angle and a second pair having a second phase angle, such that the first phase angle is less than 180.degree. displaced from the second phase angle.
Multi-position yarn handling machine including
- (a) a plurality of yarn handling positions along the machine;
- (b) respective yarn package-forming means including a package former at each said position;
- (c) respective yarn traverse guide means for each package forming means for traversing the yarn across said package former;
- and
- (d) means driving the traverse guide means such that the traverse guide means of some of said positions of the multi-position machine are traversing in a first direction while the traverse guide means of others of said positions on the same side of the machine are traversing in a second direction along the machine, said first and second directions being opposed to one another.
