Abstract
An apparatus for automated replacement of ring travelers on spinning or twisting rings is disclosed comprising generally a housing having two planar support members, parallel to each other. A lift-out device is pivotably supported in a first of the two planar members and a device for the attachment of a new ring traveler is supported in the second plane, parallel to the first plane. The devices function by guide systems, pivotable by eccentric cams, located on a common drive shaft to be able to move the two devices between an operational and an off position. A housing, containing the two devices, is mobile along a ring rail of a spinning machine. The lift-out device lifts out a ring traveler which is to be replaced from the spinning ring on the ring rail. The attachment device subsequently attaches a new ring traveler from a magazine rod onto the spinning ring. Because of the small distance in longitudinal direction between the unlatching and latching position of the ring rail, replacement of the ring traveler at the spinning ring can be accomplished in the same position of the apparatus. The magazine rod is continuously fed a new ring traveler from a coil upon which a string conta…
