SPOOIIING PROCESS.
Original application filed September 11, 1919, Serial No. 323,194. Divided and. this application filed October 22, 1923.
The spooling process as practiced in cotton mills consists in unwinding a succession of supply yarn masses, the yarn or thread of said yarn masses being Wound upon a spool or cheese core. The supply yarn masses have heretofore ordinarily been bobbin on which yarn has been wound in the manner known as Warp wind, that is to say, the yarn Was traversed up and down the bobbin While the yarn was being -Wound thereon, the traverse being gradually shortened at both ends of the bobbin as the yarn mass increased in diameter. These Warp-Wound bobbins were placed in bobbin-holders virtually constituting pockets in which the bobbins lay upon their sides, the yarn being unWo-und from the side of the bobbins, and the bobbins being thus caused to revolve. The speed at which the yarn could be unWound was limited by the Weight of the bobbin and its liability to jump in the bobbin-holder. This manner of supporting .and unwinding the supply yarn masses necessarily imposed considerable tension upon the yarn.
Another method of unwinding Which has been practiced to a slight extent consisted in using filling-Wound bobbins, that is to say, bobbins upon which the yarn had been Wound With a relatively short traverse and constant gain, the yarn being laid upon the bobbin in superposed layers of conical form. lVhen such a bobbin was employed in the spooling process, it was stationarily supported byy its butt end, the yarn being drawn oif the tip of the bobbin. The speed at which such a bobbin could be'thus un- Wound Was limited by the tendency of the yarn to form kinks which passed to the spool or cheese and caused trouble in the subsequent process of unwinding the yarn from the spools onto a. Warp beam. The speed attainable in spooling was also further limited by the tendency of the before-mentioned conical layers to come olf the bobbin in a bunch or tangle Which stopped at the thread guide and caused the running thread to break. The method of unwinding yarn which involves the drawing of the yarn off the end of filling-Wound bobbins, While desirable by reason of the lov7 tension placed upon the yarn, has therefore proved impracticable at relatively high speeds.
Serial No. 669,893.
I have discovered that a warp-Wound bobbin can be successfully univound from the end thereof, providing the unvvinding speed 1s sufficiently great, and, by employing this method, have attained a speed in spooling which is .quite extraordinary.
Referring novi7 to the accompanying drawing which is a fragmental left-hand side view of a Winder by means of which the process may be practiced: The bobbin a is supported upon a skevver 17 engaging the butt of the bobbin. The yarn F is shown as being drawn olf the upper end of the bobbin, the yarn passing thro-ugh the detector B, or other suitable guide means, and thence to a cam drum D for supporting and rotating the cheese E and traversing the yarn F. The bobbin a is an ordinary Warp bobbin having a Warp-bound yarn mass thereon. lVhen the cheese E is revolved at high speed, the yarn balloons'and thus swings clear. of the yarn mass and the tip of tlie bobbm, even when the unwinding thread extends from the lower portion of the yarn mass.
.By using Warp-Wound bobbins and unwmding the yarn thereof from the end of the .bobbin several very desirable ends are attained, namely, high speed with consequent high production, spooling under low tension, the prevention of kinking and reduced yarn breakage. Experience has shown that there is less breakage in unwinding Warp-Wound bobbins at 1200 yards per minute than in unwnding filling-Wound bobbins at 400 yards per minute.
This application is a division of my application Ser. No. 323,194 filed September l1, 1919.
I claim as my invention:
A spooling process which includes stationarlly supporting a Warp-Wound bobbin by its butt end and drawing the yarn off the .end of the bobbin at such high speed that the yarn balloons clear of the yarn mass and the tip of the bobbin.
In testimony whereof, I have hereunto affixed my signature.
BURT A, PETERSON.
