Nov. 16, 1965 R. F. BAER APPARATUS FOR TEXTURIZING YARN om 6 M i EAIHIWI mm mm 3 mm Q h mm @m B E U Q g m INVEN TOR. RUSSEL E BAER M7? ATTORN United States Patent 3,217,482 APPARATUS FOR TEXTURIZING YARN Russel F. Baer, Beloit, Wis., assignor to Monsanto Company, St. Louis, Mo., a corporation of Delaware Filed Aug. 30, 1963, Ser. No. 305,735 5 Claims. '(Cl. 576) This is a continuation-in-part of my application Serial No. 54,287, filed September 6, 1960, for Yarn Treating Apparatus, now abandoned.
This invention relates to apparatus for treating yarn and more particularly to apparatus for texturizing yarn.
It is sometimes desirable to provide a composite yarn which is made up of two different yarns texturized together which has a desired bulkiness as well as a desired resistance to tensile stresses. In the past it has been diflicult to texturize a yarn carried by a core yarn or to simultaneously texturize or bulk two yarns to different degrees. With this in mind, one of the objects of this invention is to provide a novel and improved yarn texturizing or bulking device.
Another object of this invention is to provide an apparatus for simultaneously texturizing or bulking two different yarns.
A further object of this invention is to provide a device for simultaneously texturizing and combining two yarns which may be of different characteristics.
Still another object of this invention is to provide a device for texturizing a yarn supported by a core yarn.
Another object of this invention is to provide a device for simultaneously texturizing or bulking two different yarns to different degrees.
One embodiment of this invention may contemplate a rotating tube through which a first yarn is passed to a crimping or stuffing chamber. The rotating tube imparts a false twist to the first yarn. The end of the tube adjacent to the stufling chamber terminates in an enlarged conical portion having a helical groove extending therealong. A second yarn fed into the helical groove at the larger end of the rotating enlarged portion is forced into the stuffing chamber *and wound loosely around the first yarn so that the first yarn serves as a core yarn. Steam or a heated gas is admitted to the stuffing chamber to heat and soften the yarns for the texturizing operation.
Other objects and advantages of this invention will become apparent when the following detailed description is read in conjunction with the appended drawing, in which FIGURE 1 is a partially sectioned front view of one embodiment of the invention showing the arrangement of the various elements of the device, and
FIGURE 2 is a sectional view taken on line 22 of FIGURE 1 showing the positioning of the gas inlet relative to the rotating portion of the device.
Referring now in detail to the drawing, a pair of bearings 11 and 12 adjustably secured to a base 13 are shown rotatably supporting an elongated shaft 14 having a longitudial bore 17 extending therethrough. A belt 18 passing around a pulley 19 secured to the shaft 14 drives this shaft in a well-known manner. A false twist spindle or wheel 22 is rotatably mounted on a pin 23 extending transversely through the shaft 14 for rotation therewith. I
A stuffing box or chamber 24 mounted adjustably on the base 13 is provided with a conical cavity or opening 25 which serves as a stuffing or crimping chamber, a clapper bar 26 being mounted at the exit opening of the cavity 25. A bolt 30 extends through a slot 31 in the base 13 to hold the stuffing box on the base and to provide for adjustment of the position of the stufling box.
It can be seen that a first or core yarn 34 advanced around a roller 35 and through the bore 17 to the stuffing chamber 25 will be given a false twist by the rotating shaft 14, the yarn taking a turn around the wheel 22.
3,217,482 Patented Nov. 16, 1965 This bulks the yarn 34 to a certain extent. The composite yarn is withdrawn from the stuffing chamber through a flared opening leading from the chamber 25.
The tubular shaft 14 is provided with an enlarged end or head 36 having a conical portion 37 extending into the stuffing chamber 25, the degree of taper of the portion 37 being equal to the degree of taper of the conical cavity 25. The conical portion 37 is provided with a helical groove 38 for receiving a second yarn 40 advanced through an opening 41 in the stuffing box and forcing this yarn into the stufling chamber 25. The portion 37 is positioned sufliciently close to the walls of the chamber 25 that the yarn 34 remains in the groove 38 until it reaches the end of the groove. Steam or a heated gas is admitted to the stuffing chamber 25 through a pipe 43 for heating and softening the yarns to insure the success of the texturizing or bulking operation. The pipe 43 is connected to an inlet passageway 44 which is positioned to direct the gas stream tangentially against the head 36, as best shown in FIGURE 2.
In operation of the device, the shaft 14 is driven by the belt 18 to impart a false twist to the yarn 34 being advanced through the bore 17 into the stuffing chamber 25. The yarn 40 is advanced through the opening 41 into the helical groove 38 in the portion 37 of the shaft 14. Rotation of the shaft 14 forces the yarn 40 into the stuffing chamber 25, thereby performing the texturizing or bulking operation. Because of the rotation of the shaft 14, the yarn 40 is loosely wound around the yarn 34 which serves as a core in the composite texturized yarn.
The presence of steam in the stufiing chamber causes the yarns to become soft and to take on the crimp imposed by operation of the head 36 and the clapper bar 26. The bulked yarns are withdrawn past the clapper bar 26 and from the stuffing chamber 25 through the flared opening leading from the cavity 25.
It is to be understood that the embodiment disclosed herein may be modified or altered and that other embodiments may be contemplated which will fall within the spirit and scope of the invention.
