Abstract
Abstract Improvement in or relating to an arrangement for detecting winding speed of running strandular materials on a multiple packages on a common spindle type take-up winder having multiple compensator arms with dancer rolls for the strandular materials independently operable, upon speed deviation of the strandular materials, on a common shaft connected to a unit for controlling the spindle rotational speed and the detection is carried out with possible minimum tension fluctuation within and/or between the strandular materials.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
207 words
In a winding machine having a plurality of packages mounted on a common spindle for winding a plurality of individual strands having its speed controlled by a control unit, an individual strand speed compensator device comprising a rotatable first shaft connected to the control unit for changing the winding speed by rotation of said first shaft; biasing means connected to said first shaft to apply a turning force tending to rotate said first shaft in a winding speed increasing direction; a plurality of compensator arms, one arm for each strand, each said arm extending radially with respect to said first shaft and freely rotatable thereabout; an individual first engaging member connected with each said arm and adapted to rotate therewith; an individual compensator roll mounted at the end of each arm for an individual strand to pass thereover; individual tension means connected respectively to each said compensator arm to apply a predetermined rotative tension; and a plurality of second engaging members fixedly connected to said first shaft, an individual one of said second engaging members being engaged by one of said individual first engaging members upon rotation of the respective compensator arm to thereby cause rotation of said first shaft as an individual strand increases in speed.
Claim 2
Dependent Claim
207 words
In a winding machine having a plurality of packages mounted on a common spindle for winding a plurality of individual strands having its speed controlled by a control unit, an individual strand speed compensator device comprising a rotatable first shaft connected to the control unit for changing the winding speed by rotation of said first shaft; biasing means connected to said first shaft to apply a turning force tending to rotate said first shaft in a winding speed increasing direction; a plurality of compensator arms, one arm for each strand, each said arm extending radially with respect to said first shaft and freely rotatable thereabout; an individual first engaging member connected with each said arm and adapted to rotate therewith; an individual compensator roll mounted at the end of each arm for an individual strand to pass thereover; individual tension means connected respectively to each said compensator arm to apply a predetermined rotative tension; and a plurality of second engaging members fixedly connected to said first shaft, an individual one of said second engaging members being engaged by one of said individual first engaging members upon rotation of the respective compensator arm to thereby cause rotation of said first shaft as an individual strand increases in speed.
Claim 3
Dependent Claim
40 words
A device according to claim 1 in which a first disc is provided, said first disc being mounted to rotate freely on said first shaft, and one of said compensator arms being connected thereto to provide the free rotation thereof.
Claim 4
Dependent Claim
82 words
A device according to claim 2 in which a second shaft is axially aligned with said first shaft, a second disc is fixedly mounted on said second shaft and includes one of said first engaging members mounted thereon, and an intermediate disc located between said individual first disc and said second disc is fixedly mounted on said first shaft whereby rotation of said first shaft is provided via said intermediate disc by rotative engagement of said individual first and second engagement members.
Claim 5
Dependent Claim
44 words
A device according to claim 3 in which each one of said first engaging members comprises a rod extending from a side surface of said first disc, and each one of said second engaging members comprises a rod extending radially from said intermediate disc.
Claim 6
Dependent Claim
23 words
A device according to claim 2 in which said tension means coMprises individual pulleys having tension thereon connected respectively to individual first discs.
Claim 7
Dependent Claim
66 words
A device according to claim 3 in which first magnetic means is connected to each of said first discs at a radial distance from said first shaft, second magnetic means is connected to each of said second discs at said same radial distance and at a predetermined spacing from said first magnetic means, said spacing being adjustable to provide a braking effect on the rotative movement.
Claim 8
Dependent Claim
82 words
A device according to claim 1 in which a plurality of first discs are provided corresponding in number to said compensator arms, each individual first disc being mounted to rotate freely on said first shaft, said respective compensator arm is connected thereto to provide the free rotation thereof, and a plurality of second discs are provided, each said second disc fixedly mounted on said first shaft, and each one of said second engaging members is respectively mounted on an individual second disc.
