Abstract
Abstract Apparatus for winding an advancing strand of yarn into a package is disclosed. The apparatus includes means for rotatably supporting and driving a package at a substantially constant rate of speed and means for traversing a strand onto the package as the package is rotated. Drive means for operating the traversing means is provided and regulating means for periodically increasing and decreasing the speed of the drive means as the strand is traversed onto the package is included. The control means is operable in response to the regulating means to disrupt the synchronism between the rotation of the package and the traversing of the strand onto the package to thereby prevent the formation of bands or ''''ribbons'''' wherein the strand coils in the package are crowded together or ''''piled.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
138 words
Apparatus for winding an advancing strand into a package comprising, means for rotatably supporting a package, motive means for rotating the package at a substantially constant speed, means for traversing the strand onto the package as said package is rotated, drive means for operating said traversing means, regulating means for periodically increasing and decreasing the speed of said drive means as the strand is traversed onto said package, and direction-selective means connecting said drive means and said motive means, said direction-selective means including engaging means operable when moved in a first direction To transmit to said drive means the motion of said motive means and operable when moved in a second direction to afford slippage between said motive means and said drive means to thereby disrupt synchronism between the rotatiOn of said package and traversing of said strand.
Claim 2
Dependent Claim
138 words
Apparatus for winding an advancing strand into a package comprising, means for rotatably supporting a package, motive means for rotating the package at a substantially constant speed, means for traversing the strand onto the package as said package is rotated, drive means for operating said traversing means, regulating means for periodically increasing and decreasing the speed of said drive means as the strand is traversed onto said package, and direction-selective means connecting said drive means and said motive means, said direction-selective means including engaging means operable when moved in a first direction To transmit to said drive means the motion of said motive means and operable when moved in a second direction to afford slippage between said motive means and said drive means to thereby disrupt synchronism between the rotatiOn of said package and traversing of said strand.
Claim 3
Dependent Claim
46 words
Apparatus as set forth in claim 1 wherein said direction-selective means is a clutch movable in said second direction in response to a force imparted during a decrease in the speed of said drive means to afford slippage between said motive means and said drive means.
Claim 4
Dependent Claim
46 words
Apparatus as set forth in claim 1 wherein said apparatus includes a plurality of means for supporting respective packages, said motive means being adapted to rotate all of said packages at a constant speed, and said traverse means includes a separate traverse element for each package.
Claim 5
Dependent Claim
47 words
Apparatus as set forth in claim 3 wherein said drive means is driven from said motive means, and said direction-selective means is disposed intermediate the drive means and motive means for simultaneously disrupting synchronism between rotation of each said package and the related strand being traversed thereon.
Claim 6
Dependent Claim
46 words
Apparatus as set forth in claim 4 wherein said direction-selective means is a clutch movable in said second direction in response to a force imparted during a decrease in the speed of said drive means to afford slippage between said motive means and said drive means.
Claim 7
Dependent Claim
90 words
Apparatus as set forth in claim 5 wherein said traverse means includes an elongated rod adapted to support each said traverse element at a location thereon proximate to its associated package, means mounting said rod for reciprocation to cause each traverse element to reciprocate relative to its associated package to distribute a strand thereon, the rate of reciprocation of each said traverse element being varied in response to periodic increases and decreases in the speed of said drive means and slippage imparted as said clutch moves in said second direction.
