Because the reeling of a smooth yarn too rigor and in particular the then subsequent reverse bobbin winding of austerity puffy garnes costly and are demanding operations, non-bulky yarns are mostly used in the manufacture of textiles such as woven and knitted fabrics. These products must be used for a later scrubability and the associated Bulging can be made looser. The production of a loose product, however, has its drawbacks, for example because it is unusual wide working widths on the fc & machines and different Trigger devices are necessary. The quality of the also points to this kind of produced goods many defects, such as streakiness, restless appearance and the like. For these reasons - it is therefore more advantageous to to work with a yarn that has already been made puffy. The previously known methods and devices however, do not allow a productive solution to this problem, Especially when using higher yarns. Unit numbers.

The method and apparatus according to the invention eliminate these subject parts. It is the object of the invention to provide uninterrupted bulking of the yarns in connection with some other operations, such as spooling, weaving, knitting, and uninterrupted ringless ^ spinning

to enable, whereby special technological processes in connection with the bulk of austerities are omitted.

In solving this task, the disadvantages of the Bulging of finished textile bags removed and the quality of products made from bulky staple fiber yarns improved, leading to the adoption of a larger expansion, of this otherwise economically advantageous type of products encouraged.

The essence of the method according to the invention consists in that the yarn is continuously collected to a Jieserve and withdrawn from it while it is being reeled, while remaining in the reserve, it is made fluffy by 'Tcrmeeinwlricung.

The Ί / esen of the device for carrying out the method According to the invention, there is a small chamber is designed as a bulk chamber, - in its entry point heated a nozzle for feeding,. gaseous medium and for yarn conveying in the Bauschlcamuser mü

Fig. 1 is a schematic elevation view of an embodiment

Fig. 2 - a schematic representation of a bulking chamber in longitudinal section

Fig. 3 - a schematic cross section through the Bulk chamber.

In the exemplary embodiment according to FIG. 1, the yarn 1 from a door position 2 through a driver eye and brake 3 ° guided between delivery or feed rollers 4 to a feeder nozzle 5. Warm compressed air flows through this, Superheated steam or another suitable medium, whereby the yarn 1 is conveyed into the bulk chamber 6. Depending on the size of this chamber and the withdrawal speed the yarn a certain reserve 16 and thus remains a certain time in this electoral chamber.

If the building chamber 6 is heated electrically, for example, or if a warm medium, for example steam or warm air and the like, is fed into the small chamber with the aid of the nozzle 5, the yarn components will bulge as a result of the different shrinkability of the yarn components. The puffed yarn is passed on from the pile chamber 6 in lease to a brake and wound onto a spool 8 , which receives the necessary rotation by resting on a thread guide drum 9. . ■ ".

The relationship between the take-up and take-up speeds is variable depending on the desired degree of bulge. V - ·.

In the ü'ig. 2, the bulk chamber 6 is shown in detail. As already described, the yarn 1 is fed through the delivery or feed rollers 4 into the nozzle 5, from which it is conveyed further into the interior of the bulking chamber 6, where it is released in the direction from the outlet 10 to the inlet 11 of the small chamber stores. The warm medium flowing out of the D-'se 5 into the Kieinkamtner, which conveys the yarn 1 and at the same time heats it, causes the bulging effect in the yarn. The dumbbell is perforated so that the yarn 1 is deposited in the entire interior of the bulking chamber The medium that passes through the stacked yarn 1 also flows along the flutes and thus supports the constant advance of the stacked yarn in the direction of the outlet 10, the chamber 6, whereby the latter is completely filled gradually increasing cross-section from the chamber inlet 11 in the direction of the chamber outlet 10. Meanwhile, the cross-section of the bulge chamber 6, which is circular, elliptical and

table., square, rectangular and the like.

The feeder nozzle 5, which forms part of the .bauschkammer 6, is connected to a source, not shown, of a correspondingly temperature-controlled pressure medium. This nozzle serves both to feed the yarn 1 into the building chamber 6 and to stop the yarn supply in the event that the building chamber 6 is full. "

The gaseous medium flows in the direction of arrow 14 through the nozzle 5, * - whereby it entrains the yarn 1 and into the ■ Bauschkammer 6 brings. The gaseous medium then flows out of the outlet 10 and the holes 12 of the BauschkanKier into the open. For the purpose of a good working method, it is advantageous if at least some of the holes 12 are partially in the direction of runs to exit 10.

As soon as the bulk chamber 6 is full of yarn 1, the nozzle 5 automatically stops feeding the yarn, because the yarn clogs the outlet 10 and also the holes 12. The gaseous medium then flows out through that opening 15 of the nozzle 5 through which the yarn 1 enters the Nozzle.

Instead of the delivery or feed rollers 4, it is advantageous to use a godet (not shown). It is also possible to provide the ball chamber 6 with a Minier 17, which tracks the state of the Garnfüllung in the Bausch chamber and the delivery or feed rollers 4> optionally the godet controls such that free .Anfüllung the Bausch chamber verlang- 6, this extraction elements 'seeds, or come to a standstill. The sensor 17 can in one case control the mentioned extraction elements or the nozzle 5, while in the other case the extraction elements and the nozzle are controlled simultaneously. Instead of the sensor 17, which tracks the yarn supply in the pile chamber 6, a sensor can also be used which reacts to the pressure conditions in the nozzle 5.

A solution is also advantageous which is used in known winding where the yarn is present its path between the Khotenbildner and wound spool accumulates as a reserve, so that its (speed suddenly decreases. If the yarn breaks accidentally, the yarn from the reserve continues to be unwound, while a new yarn is tied to the end of the yarn reserve which is at rest. The reserve is then put on for further use Tying the yarn and this at a speed that is higher than the winding speed.
