Abstract
Abstract Apparatus for automatically supplying empty bobbins to a windup position and for carrying a woundup bobbin to a discharge position. The apparatus comprises a rotatable cage having a plurality of bobbin-receiving means and which cage is indexed so as to carry a bobbin from one position or station to yarnwinding-up position and thence to the discharge position. Conveniently the apparatus consists of a series of cages mounted for rotation on a common shaft.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
198 words
Apparatus for continuously supplying at each of a plurality of side-by-side stations a bobbin to a yarn-winding position and removing from the position such bobbin when a determined supply of yarn has been wound thereon comprising at each station: a drive roll for engaging a bobbin and driving the same by surface contact; yarn traverse means for traversing yarn axially of a bobbin at such station; a bobbin-carrying cage mounted so as to rotate about an axis parallel to the axis of the drive roll; a plurality of bobbin-carrying means equidistantly spaced around and pivotally mounted on said cage for carrying bobbins in positions in which their axes are parallel to the axis of the drive roll; resilient means urging said bobbin-carrying means into a position such that when one of such carrying means is adjacent the drive roll a bobbin carried by the carrying means is urged into driving contact with the drive roll; bobbin-supply means; and means for rotating the cage in a stepwise manner to carry a bobbin received from the bobbin-supply means to the drive roll, said cages and said drive rolls being carried by shafts which are common to the plurality of stages.
Claim 2
Dependent Claim
198 words
Apparatus for continuously supplying at each of a plurality of side-by-side stations a bobbin to a yarn-winding position and removing from the position such bobbin when a determined supply of yarn has been wound thereon comprising at each station: a drive roll for engaging a bobbin and driving the same by surface contact; yarn traverse means for traversing yarn axially of a bobbin at such station; a bobbin-carrying cage mounted so as to rotate about an axis parallel to the axis of the drive roll; a plurality of bobbin-carrying means equidistantly spaced around and pivotally mounted on said cage for carrying bobbins in positions in which their axes are parallel to the axis of the drive roll; resilient means urging said bobbin-carrying means into a position such that when one of such carrying means is adjacent the drive roll a bobbin carried by the carrying means is urged into driving contact with the drive roll; bobbin-supply means; and means for rotating the cage in a stepwise manner to carry a bobbin received from the bobbin-supply means to the drive roll, said cages and said drive rolls being carried by shafts which are common to the plurality of stages.
Claim 3
Dependent Claim
40 words
Apparatus according to claim 1 wherein there is provided a collector onto which a fully wound yarn package is automatically deposited as the package is caused to move away from the drive roll during a rotational movement of the cage.
Claim 4
Dependent Claim
26 words
Apparatus according to claim 2 wherein automatic means is provided for severing yarn from a fully wound package during its passage away from the drive roll.
Claim 5
Dependent Claim
27 words
Apparatus according to claim 3 wherein the said cage is automatically moved in a stepwise manner to carry yarn bobbins towards and away from said drive roll.
Claim 6
Dependent Claim
67 words
Apparatus as in claim 1 wherein each station includes an auxiliary drive roll for engaging a bobbin and driving the same by surface contact, said auxiliary drive roll being disposed a location in advance of the first-mentioned drive roll with respect to the direction of rotation of the cage whereby a given bobbin is already rotating when it is brought into contact with the first-mentioned drive roll.
