APPARATUS FOR TREATING YARN Filed March 26, 1962 lll/II.'
INVENTOR. RUSSEL F. BAER ,QZ/fi.
ATTORNEY United States Patent O "ice 3,147,533 APPARATUS FOR TREATING YARN Russel F. Baer, Decatur, Ala., assigner, by mesne assignments, to Monsanto Company, a corporation of Delaware Filed Mar. 26, 1962, Ser. No. 182,259 1 Claim. (Cl. 28-1) This invention relates to apparatus for treating yarn and more particularly to apparatus for texturizing yarn.
In the texturizing of thermoplastic chemical yarns several approaches are used. In some cases, patterned crimping rolls are used, while in others stuiing boxes are used. False twisting is also used for imparting a non-linear conguration to chemical tilaments. Each of these has advantages and disadvantages; and each of them usually produces a diierent type of crimp or coniiguration in the yarn. With this in mind one of the objects of this invention is to provide a novel and improved yarn treating apparatus.
Another object of this invention is to provide an apparatus for imparting a false twist to a yarn.
A further object of this invention is to provide an apparatus which utilizes a stuiiing box or chamber for texturizing a yarn.
Still another object of this invention is to provide an apparatus which texturizes a yarn by utilizing both a stuffing chamber and false twisting.
A still further object of this invention is to provide an apparatus wherein a pair of rolls force a yarn into a stuing box or chamber which is rotated to impart a false twist to the yarn.
One embodiment of the present invention contemplates a yarn texturizing apparatus having a rotatably mounted stuiling box or chamber. A pair of rolls mounted on the chamber force the yarn into the chamber, the rolls being carried with the rotating chamber. The rolls are connected to meshed gears which cause the rolls to be rotated together. One of the gears is meshed with a xed annular or internal gear so that rotation of the chamber drives the gears and the rolls to force the yarn into the chamber, the rotation of the chamber imparting a false twist to the yarn.
Other objects and advantages of the invention will become apparent when the following detailed description is read in conjunction with the appended drawing, in which- FIGURE 1 is a cross sectional view of one embodiment of the invention showing the arrangement of the various elements of the apparatus,
FIGURE 2 is a sectional view taken on line 2 2 of FIGURE 1 showing the positioning of the roll driving gears relative to the xed internal gear, and
FIGURE 3 is a view taken on line 3 3 of FIGURE 1 showing the manner in which the rolls and the roll drive gears are mounted on the crimping chamber.
Referring now in detail to the drawing, a frame 11 is shown supporting a crimping chamber 12, the chamber 12 being rotatably mounted on bearings 15 and 16. The chamber 12 includes a tubular member 17 secured in the bearing 15 and slidably mounted in a sleeve 1S which is secured to the bearing 16.
The bore 21 of the tube 17 serves as the crimping chamber, the upper end of the tube 17 being provided with a conical opening 24 connected to the bore 21 and leading 3,147,533 Patented Sept. 8, 1964 into the sleeve 13. The conical opening 24 and the bore 25 of the sleeve 18 form an enlarged chamber at the upper end of the tube 17. A hole 28, interconnected with the bore 25 by a conical opening 29, serves as an exit opening from the crimping chamber.
A yoke 31 secured to the lower end of the tube 17 is provided with a pair of spaced, depending anges 32 and 33 having apertures for receiving shafts 36 and 37. A pair of rolls 41 and 42 secured to the shafts 36 and 37, respectively, and positioned between the ilanges 32 and 33 are provided for forcing a yarn 43 through a bore 44 in the yoke 31 into the chamber 12.
The rolls 41 and 42 are driven by pairs of gears 47 and 48 secured to the shafts 36 and 37 and meshed with each other. The gears 48 are meshed with an annular or internal gear 5@ secured to the frame 11 by bolts 51. The teeth 52 on the annular gear 5@ are so constructed that rotation of the chamber 12 causes the gears 47 and 48 to rotate, thereby forcing the yarn 43 into the chamber. The teeth on the annular gear 5@ more nearly resemble the threads in a nut having a very high pitch. Doctor blade portions 55 and 56 on the yoke 31 insure that none of the yarn wraps around the rolls 41 and 42.
The annular gear 50 is positioned eccentrically relative to the axis of rotation of the chamber 12 so that only the gears 4S engage the annular gear. A pulley 60 secured to the tube 17 is driven by a belt 61 to rotate the chamber.
The position of the sleeve 18 on the tube 17 can be adjusted to change the length of the stuing chamber. A spring 64 urges the sleeve 13 upward on the tube 17. The upper bearing is held by an apertured insert 65 which is slidably mounted in a bore 66 in the frame 11. A spring 69, held in place by an apertured nut '70 threaded into the bore 66, serves to urge the insert 65 and the sleeve 13 downward against the action of the spring 64. By adjusting the'position of the nut 70 the position of the sleeve 18 can be adjusted, thereby changing the length of the crimping chamber.
A pair of takeup rolls 72 are used for withdrawing the texturized yarn from the chamber, the yarn passing upward through the hole 28, the apertured insert 65 and the apertured nut 70.
In operation, the belt 61 drives the pulley 60 to rotate the crimping chamber 12. Rotation of the chamber 12 causes the gears 47 and 48 to rotate and drive the rolls 41 and 42, since the gears 47 and 48 are carried by the chamber 12 and since the gears 48 are meshed with the internal gear 50.
Rotation of the rolls 41 and 42 forces the yarn 43 into the chamber 12, thereby crimping the yarn. Rotation of the chamber 12 also imparts a false twist to the yarn. This false twisting combined with the crimping of the yarn insures that the yarn is fully texturized.
It is to be understood that the embodiment disclosed herein is merely illustrative and that numerous other ernbodirnents can be contemplated without departing from the spirit and scope of the invention.
What is claimed is:
An apparatus for texturizing a yarn, comprising a frame, a tubular member, a sleeve adjustably positioned on one end of the tubular member to form a chamber, said tubular member and said sleeve being rotatably mounted on the frame, a yoke secured to the other end of the tubular member and having a pair of spaced flanges, a pair of shafts mounted on the anges, a pair of rolls positioned between the ilanges and secured to the shafts for forcing a yarn into the chamber, a rst pair of drive gears secured to the ends of one of the shafts, a second pair of drive gears secured to the ends of the second shaft and meshed with the rst pair of drive gears, an internal gear mounted on the frame and meshed with the first pair of drive gears for rotating the drive gears and the rolls when the chamber is rotated, means for rotating the chamber, a spring mounted on the tubular member and engaging the sleeve for urging said sleeve in a direction away from the yoke, and means engaging the sleeve for resisting the action of the spring, said resisting means being adjustable in position to adjust the position of the sleeve on the tubular member.
