Bobbin winding machine

Claim 2

A bobbin winding machine comprising, in combination, a rotatable, elongated arbor adapted to receive and to rotate a plurality of identical bobbins that are assembled thereon, means mounting said arbor for rotation and for rotating said arbor and said bobbins, means for mounting a supply of thread, a thread guide including a tensioning device for guiding the thread from the supply onto said bobbins, a guide way for said guide extending parallel to the axis of rotation of said arbor, indexing means for moving said guide along said way in increments of distance corresponding to the axial width of one of said bobbins, means for counting the revolutions of said arbor and for delivering a signal upon the completion of a number of revolutions of said arbor predetermined to result in the winding of a certain length of thread on a bobbin and means responsive to such signal for actuating said indexing means to move said guide forwardly along said way two increments of distance and returning said guide one increment of distance for transferring the thread off of a wound bobbin and onto the next adjacent empty bobbin.

Claim 3

A machine according to claim 1 in which the thread guide comprises an elongated bar movable along the guideway and said indexing means comprises a plurality of vertical stops positioned on said bar that are spaced from each other even increments of distance along said bar, and a feeder mounted adjacent to and for forward and return reciprocation along said guideway, said feeder having means engageable successively with said stops.

Claim 4

A machine according to claim 2 in which the feeder comprises two dogs which are alternately engageable with the stops on the thread guide bar, one of said dogs being engageable during the forward movement of said feeder and the other of said dogs being engageable during the return movement of said feeder, and means for disabling the other one of said dogs during the first increment of distance of movement of said feeder during the return stroke thereof.

Claim 5

A machine according to claim 1 in which the means for counting the revolutions of the arbor comprises a magnetized lamination on a segment of the arbor mounting means and a counter responsive to the passage of such lamination mounted adjacent to said arbor mounting means.

Claim 6

A machine according to claim 3 and mechanism for moving said feeder comprising a solenoid for moving said feeder forwardly two increments of distance upon each actuation thereof.

Claim 7

A bobbIn-winding machine comprising, in combination, a rotatable, elongated arbor adapted to receive and to rotate a plurality of identical bobbins that are assembled thereon, means mounting said arbor for rotation and for rotating said arbor and said bobbins, means for mounting a supply of thread, a thread guide including a tensioning device for guiding the thread from the supply onto said bobbins, a guide way for said guide extending parallel to the axis of rotation of said arbor, indexing means for moving said guide along said way in increments of distance corresponding to the axial width of one of said bobbins, means for counting the revolutions of said arbor and for delivering a signal upon the completion of a number of revolutions of said arbor predetermined to result in the winding of a certain length of thread on a bobbin and means responsive to such signal for actuating said indexing means to move said guide forwardly from a winding position along said way a distance in excess of one increment of distance and returning said guide to one increment of distance from such winding position for transferring the thread off of a wound bobbin and onto the next adjacent empty bobbin.

Claim 8

A bobbIn-winding machine comprising, in combination, a rotatable, elongated arbor adapted to receive and to rotate a plurality of identical bobbins that are assembled thereon, means mounting said arbor for rotation and for rotating said arbor and said bobbins, means for mounting a supply of thread, a thread guide including a tensioning device for guiding the thread from the supply onto said bobbins, a guide way for said guide extending parallel to the axis of rotation of said arbor, indexing means for moving said guide along said way in increments of distance corresponding to the axial width of one of said bobbins, means for counting the revolutions of said arbor and for delivering a signal upon the completion of a number of revolutions of said arbor predetermined to result in the winding of a certain length of thread on a bobbin and means responsive to such signal for actuating said indexing means to move said guide forwardly from a winding position along said way a distance in excess of one increment of distance and returning said guide to one increment of distance from such winding position for transferring the thread off of a wound bobbin and onto the next adjacent empty bobbin.

Claim 9

A machine according to claim 6 in which said indexing means comprises a solenoid for moving said feeder forwardly along said way a distance at least equal to two increments of distance.
