Abstract
Abstract A high-speed winding apparatus for producing a filamentary spool package on a spool sleeve including spool holder means which engages the spool sleeve and which is rotatably mounted by means of a first set of anti-friction bearings onto a spool carrier which in turn is rotatably mounted by means of a second set of anti-friction bearings onto a support member. Drive means are provided to at least rotatably drive said spool holder means either directly or by a friction roll contacting the cylindrical surface of the spool package. The spool carrier is preferably also driven by a common or separate drive means at rotational speed proportionately slower than said spool holder means. The apparatus is especially useful for the take-up winding of filaments, threads, yarns or the like as employed in spin-drawing and high-speed spinning machines requiring linear winding speeds in excess of 5,000 meters/minute and spool revolutions of more than 30,000 rpm.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
141 words
In a winding apparatus for producing a filamentary spool package on a spool sleeve at high rotational speeds of the spool, the improvement which comprises: a spool holder means to interchangeably receive and engage said spool sleeve on a horizontal axis for rapid winding; a spool carrier on which said spool holder means is rotatably mounted through a first paired set of anti-friction bearings; a multi-element assembled supporting member on which said spool carrier is cantilevered and rotatably mounted only at its inboard end, which extends axially from said spool holder means, through a second paired set of anti-friction bearings, each set of bearings being contained in a separately assembled element adjacent either end of said supporting member; and means for driving said spool carrier relative to said spool holder means at a rate proportionately slower than said spool holder means.
Claim 2
Dependent Claim

In a winding apparatus for producing a filamentary spool package on a spool sleeve at high rotational speeds of the spool, the improvement which comprises: a spool holder means to interchangeably receive and engage said spool sleeve on a horizontal axis for rapid winding; a spool carrier on which said spool holder means is rotatably mounted through a first paired set of anti-friction bearings; a multi-element assembled supporting member on which said spool carrier is cantilevered and rotatably mounted only at its inboard end, which extends axially from said spool holder means, through a second paired set of anti-friction bearings, each set of bearings being contained in a separately assembled element adjacent either end of said supporting member; and means for driving said spool carrier relative to said spool holder means at a rate proportionately slower than said spool holder means.
Claim 3
Dependent Claim
20 words
A winding apparatus as claimed in claim 1 wherein said anti-friction bearings are roller bearings in each of said sets.
Claim 4
Dependent Claim
28 words
A winding apparatus as claimed in claim 1 wherein said driving means includes a friction roll drive placed in direct rolling contact with the spool package being formed.
Claim 5
Dependent Claim
34 words
A winding apparatus as claimed in claim 1 wherein said driving means includes a rotary drive assembly operatively connected to said spool holder means for high speed rotation of the spool package being formed.
Claim 6
Dependent Claim
51 words
Winding apparatus as claimed in claim 1 wherein said driving means includes means operatively connected to rotate only said spool holder means with said spool carrier being mounted for free rotation, said spool carrier being rotated by means of the frictional bearing force imparted by the first set of anti-friction bearings.
Claim 7
Dependent Claim
36 words
Winding apparatus as claimed in claim 1 wherein said driving means includes a separate transmission means for said spool holder means and said spool carrier and a common drive means coupled to each said transmission means.
Claim 8
Dependent Claim
54 words
Winding apparatus as claimed in claim 1 wherein said supporting member for said spool carrier and said spool holder means is mounted in a fixed position to provide a stationary spool axis and a filament traversing device is mounted to move outwardly from said stationary spool axis with increasing diameter of the spool package.
Claim 9
Dependent Claim
56 words
Winding apparatus as claimed in claim 1 wherein a filament traversing device is fixed for traversing movement in a stationary plane with the supporting member for said spool carrier and said spool holding means being mounted for movement of the spool axis outwardly from the fixed traversing device as the diameter of the spool package increases.
