Abstract
Abstract In winding a yarn onto a bobbin, the free end is first drawn and held by a suction device adjacent the rotating bobbin. A jet of air moves the yarn in close proximity to the bobbin for engagement by a catcher. A cutter severs the yarn adjacent the catcher and the yarn is wound on the bobbin while the waste is carried away by the suction device. Upon filling the bobbin the yarn is cut and again engaged by the suction device. An empty bobbin is then substituted for the full bobbin and the cycle is repeated.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
169 words
A process for automatically winding a yarn from a supply source onto a plurality of bobbins in succession comprising: subjecting the free end of said yarn to a first fluid force adjacent one end of said bobbin to shift said yarn to a position outside the regular traversing range of the yarn across the bobbin to provide the necessary clearance for a bobbin changing operation, applying a second fluid force to shift the free end of said yarn into engagement with the bobbin, rotating the bobbin by drive means to wind the yarn on the bobbin to a predetermined size, disengaging the wound bobbin from said drive means to provide a slack in said yarn, subjecting said slack yarn to said first fluid force to shift said slack yarn to said position outside the regular traversing range of said yarn across the bobbin, cutting the yarn adjacent the end of said bobbin so that the free end of said yarn will be properly disposed for a subsequent winding operation.
Claim 2
Dependent Claim
169 words

Claim 3
Dependent Claim
34 words
A process as set forth in claim 1 further comprising, cutting the waste from the free end of the yarn after shifting said yarn into engagement with the bobbin by said second fluid source.
Claim 4
Dependent Claim
28 words
A process as set forth in claim 2 further comprising removing said waste by creating a suction zone adjacent the end of said bobbin where said cutting occurs.
Claim 5
Independent Claim
194 words
An apparatus for winding a continuously fed yarn comprising, a continuous yarn supply source for supplying a yarn having a free end, a yarn injection nozzle for placing the free end of the yarn in a predetermined axial position, a rotatable bobbin rotatably mounted at a space-apart distance from said yarn injection nozzle, yarn traversing means mounted adjacent said bobbin between said bobbin and said yarn injection nozzle for traversing said yarn onto said bobbin, a fluid suction nozzle positioned adjacent one end of said bobbin for attracting the free end of a yarn being supplied from said supply source, a waste yarn collector fluidically connected to said fluid suction nozzle, a fluid injection nozzle mounted in proximity to said fluid suction nozzle adjacent said one end of said hollow nozzle for moving said yarn laterally for moving said yarn laterally into engagement with said bobbin, a yarn cutter positioned between said fluid injection nozzle and said yarn traversing means, and control and timing means operatively connected to said yarn injection nozzle, said fluid suction nozzle, said fluid ejection nozzle, and said cutter to sequentially control each of said elements in a predetermined sequence.
