Abstract

Abstract A take-up machine having a rotating spindle on which a tube is releasably clamped for winding of a strand of yarn onto the tube to form a yarn package. The machine automatically threads the strand of yarn onto the spindle to start winding of the yarn onto the tube and, if desired, first winds a tailing end about an end of the tube, and then winds a body of yarn on the tube to form the yarn package. A variable speed spindle drive is automatically operated at a manually pre-set constant speed during thread-up and immediately upon thread-up is switched to a speed different from the constant pre-set speed and conventional control of the winding speed.

Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 139 words
Apparatus for winding a strand comprising, means for advancing the strand at a delivery speed, winding means for receiving the strand from the advancing means and winding the strand into a package, drive means for rotating the winding means, means for operating the drive means in a constant speed mode to rotate the winding means at a constant speed a commencement of winding of the strand onto said winding means, said constant speed being correlated with delivery speed so as to ensure proper initial winding of the strand onto the winding means, and actuator means operable in response to the commencement of winding of said strand on said winding means to shift the operation of said drive means to a variable speed mode whereby the speed of rotation of said winding means can be adjusting Said package is wound.
Claim 2
Dependent Claim 139 words
Apparatus for winding a strand comprising, means for advancing the strand at a delivery speed, winding means for receiving the strand from the advancing means and winding the strand into a package, drive means for rotating the winding means, means for operating the drive means in a constant speed mode to rotate the winding means at a constant speed a commencement of winding of the strand onto said winding means, said constant speed being correlated with delivery speed so as to ensure proper initial winding of the strand onto the winding means, and actuator means operable in response to the commencement of winding of said strand on said winding means to shift the operation of said drive means to a variable speed mode whereby the speed of rotation of said winding means can be adjusting Said package is wound.
Claim 3
Dependent Claim 22 words
Apparatus as set forth in claim 1 including means for severing the strand as said strand commences winding onto said winding means.
Claim 4
Dependent Claim 34 words
Apparatus as set forth in claim 1 including means for releasably positioning the strand for winding a tailing end on said winding means and for releasing the strand to commence winding of said package.
Claim 5
Dependent Claim 42 words
Apparatus as set forth in claim 3 including means mounting the positioning means for movement between a holding position for positioning the strand to wind the tailing end and a releasing position for releasing the strand to commence winding of the package.
Claim 6
Dependent Claim 54 words
Apparatus as set forth in claim 1 including a strand collector to which the strand is delivered prior to being wound to said winding means, and handling means mounted proximate said winding means and engagable with said strand intermediate said collector and said winding means to commence the strand winding onto said winding means.
Claim 7
Dependent Claim 35 words
Apparatus as set forth in claim 5 wherein said handling means includes severing means operable to sever the strand between said winding means and said collector as said strand commences winding on said winding means.
Claim 8
Dependent Claim 65 words
Apparatus as set forth in claim 5 wherein said handling means includes positioning means operable between a holding position for positioning the strand to wind a tailing end on said winding means and a releasing position for releasing the strand for commencement of winding of said package, and the handling means includes a movable member for moving the strand into engagement with said positioning means.
Claim 9
Dependent Claim 18 words
Apparatus as set forth in claim 7 including means yieldably urging the positioning means to its holding position.
Claim 10
Dependent Claim 25 words
Apparatus as set forth in claim 1 wherein the drive means is electrically operated means, and including an electrical circuit for operating the drive means.
Claim 11
Dependent Claim 47 words
Apparatus as set forth in claim 9 wherein the actuator means includes an automatic speed controller and motor controller connected in said electrical circuit for operating said drive means in said variable speed mode and thereby maintaining substantially constant tension of the strand during the winding operation.
Claim 12
Dependent Claim 90 words
Apparatus as set forth in claim 10 wherein said electrical circuit includes a potentiometer for operating said drive means in said constant speed mode. 12 Apparatus as set forth in claim 11 wherein said actuator further includes a compensator mechanism engagable with the strand as said strand advances to said winding means, said actuator means being operable in response to sensing of the tension condition of said strand by said compensator mechanism to shift the operation of said drive means from said constant speed mode to said variable speed mode.
Claim 13
Dependent Claim 75 words
Apparatus as set forth in claim 12 wherein the compensator mechanism is movable in response to tension variations in the strand, and said actuating means is operated in response to a tension increase in said strand. 14 Apparatus as set forth in claim 11 wherein said electrical circuit includes a holding relay for preventing said drive means from being shifted from said variable speed mode to said constant speed mode during winding of said package.
Claim 14
Dependent Claim 50 words
Apparatus as set forth in claim 9 including a collector to which the strand is delivered prior to being wound on said winding means, strand engaging means for commencing the strand winding on said winding means, and means for severing the strand as it starts winding onto the winding means.
Claim 15
Dependent Claim 46 words
Apparatus as set forth in claim 15 wherein the strand engaging means including receiving means on the winding means for receiving and starting the strand winding onto the winding means and guiding means for moving the strand into position to be received by said receiving means.
Claim 16
Dependent Claim 47 words
Apparatus as set forth in claim 16 wherein said strand engaging means includes positioning means operable between a holding position for positioning the strand to wind a tailing end on said winding meaNs and a release position for releasing the strand to commence winding of the package.
Claim 17
Dependent Claim 18 words
Apparatus as set forth in claim 17 including means yieldably urging the positioning means to its holding position.
Claim 18
Dependent Claim 16 words
Apparatus as set forth in claim 5 including means for pneumatically operating said strand engaging means.
Claim 19
Dependent Claim 16 words
Apparatus as set forth in claim 5 including means for manually operating said strand engaging means.
