Abstract
Abstract Method and apparatus are disclosed for transferring yarn from a completed yarn package to an empty reel in a continuous yarn winding process whereby a plurality of yarn winding arbors are rotated around a centrally located drive roller. Rotation is caused by interaction of spring tensioned arbors along a cam guide which positions the arbors relative to the drive roller.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
225 words
A continuous yarn winding apparatus comprising a frame, an incrementally rotatable turret attached to said frame by a hub and series of spokes; an arbor driving roller attached to said frame concentric to the turret; first and second yarn winding arbors slidably attached to said spokes to move in and out of engagement with said arbor driving roller; yarn traversing means adjacent said driving roller for depositing yarn from a yarn supply onto the winding arbors to form a yarn package; spring means for urging the winding arbors toward said hub and into engagement with said arbor driving roller; a cam guide having an arbor engaging face continuous through the rotational increment of the turret from an outermost position of the second winding arbor to a position adjacent said driving roller the interaction of the cam guide and spring means tending to cause rotation of the turret around the arbor driving roller while simultaneously guiding the second winding arbor along the spokes and into contact with the arbor driving rollers; turret detent means for restraining rotation of the turret with said second yarn winding arbor in the outermost position until a yarn package has been formed on said first yarn winding arbor; and means for transferring yarn from the yarn traversing means to the second yarn winding arbor after it has engaged the driving roller.
Claim 2
Dependent Claim
225 words
A continuous yarn winding apparatus comprising a frame, an incrementally rotatable turret attached to said frame by a hub and series of spokes; an arbor driving roller attached to said frame concentric to the turret; first and second yarn winding arbors slidably attached to said spokes to move in and out of engagement with said arbor driving roller; yarn traversing means adjacent said driving roller for depositing yarn from a yarn supply onto the winding arbors to form a yarn package; spring means for urging the winding arbors toward said hub and into engagement with said arbor driving roller; a cam guide having an arbor engaging face continuous through the rotational increment of the turret from an outermost position of the second winding arbor to a position adjacent said driving roller the interaction of the cam guide and spring means tending to cause rotation of the turret around the arbor driving roller while simultaneously guiding the second winding arbor along the spokes and into contact with the arbor driving rollers; turret detent means for restraining rotation of the turret with said second yarn winding arbor in the outermost position until a yarn package has been formed on said first yarn winding arbor; and means for transferring yarn from the yarn traversing means to the second yarn winding arbor after it has engaged the driving roller.
Claim 3
Dependent Claim
97 words
The continuous yarn winding apparatus of claim 1 wherein said means for transferring yarn comprises, a yarn deflecting arm rotatably mounted on said frame and movable into the part of the yarn being wound onto said first yarn winding arbor from said yarn traversing means; a first rotary solinoid device for rotating, when actuated, said yarn deflecting arm to an intermediate position, restraining the yarn from said traversing means; a second rotary solinoid device for further rotating, when actuated, said yarn deflecting arm into an extended position to divert said yarn to the second yarn winding arbor.
