Process for withdrawing the carded fibers from the working surface of the carding element during continuous ringless ■ Spinning of textile fibers and one used for this

Contraption. ~

The invention relates to a method for withdrawing the dissolved fiber material from the working surface of the carding element during the continuous ringless spinning of textile fibers and a device for carrying out this method _{or the like}

The previously known devices for the continuous ringless spinning of textile fibers consist of one Combing element, i.e. a combing roller, and a thread-forming element, i.e. a spinning chamber, and the mechanisms for the delivery of the dissolved fibers to the collecting surface of the spinning chamber, in the form of a guide channel with a stationary so-called septum or with a knife and from a working organ for the orientation of the

dissolved fiber material on the Samrael surface of the Spinning chamber.

The above mentioned labor organization verier.-err de *. Ties; aes to be processed fiber material from their take-off & parts in the 'IxS.rdierorgan to the discharge point at the spinning chamber, which is both technologically _{disadvantageous, ie 0} p- with consideration of an uneven fiber supply, as well as construction-technically disadvantageous.

The invention relates to a new method for deduction dissolved fibers from the working surface of the cardiac organ in the continuous ringless spinning of textile fibers and should avoid the above-mentioned disadvantageous parts as well as the Ensure the shortest possible V / eg between the carding element and the thread-forming working element.

In principle, the method of the invention is that P combing roll the dissolved fiber material from the working surface of the training ψ is drawn off directly through the septum of the rotary spinning chamber.

According to the invention, it is also possible to pull the dissolved fiber material to be processed directly from the working surface of the combing roller through the partition of the rotating spinning chamber with the simultaneous action of a pressure medium flowing between the partition and the working surface, in the opposite direction to the rotary
