Description

Device for guiding the sliver, carding the fiber material and transporting it to that for continuous ringless spinning

certain spinning device

The invention relates to a device for guiding the tape, the carding of the fiber material and its delivery into the device intended for continuous ringless spinning.

In the classic spinning process, as well as in the abbreviated spinning process, there are various methods of refinement and of carding a coarse sliver into a fine fiber ribbon, from which a thread is formed is known. Most often, drafting systems of various designs are used for this purpose and in different versions with a different

Number of Streok zones and stretch roller ^ used, but di © at higher delivery speeds and higher requirements the uniformity of the ribbon is not sufficient Ensure quality .; whereby} 'especially with the abbreviated Spinning process of sliver, unsatisfactory results in terms of yarn negligence. be achieved can"

Another disadvantage is when the working speed is increased during the delay in the winding formation of the fibers on the stretching or legging whales «This brings a great danger, especially with fast-running streek rollers and if the operator does not pay enough attention, the entire stretch of the drafting system can be damaged cause.

There are also several with for continuous ringless Spinning certain spinning devices cooperating carding devices described, which however - what the delivery of the fiber material to the carding organs and its dissolution for the purpose of subsequent spinning, - do not work properly and under no circumstances a proper tape guide, Controlling the fibers during the carding process and preventing the fibers from kinking on the feed roller ensure the delivery system, which is particularly due to the excessive distance between the combing and feed roller is due.

The purpose of this invention is to eliminate alia? mentioned Disadvantage of the known Eardiervorriohtungen, the backup

a perfect sliver guidance to the carding organs, a perfect carding of the fiber material, its transport to the spinning device and the elimination of the winding formation on the feed roller.

In principle, the invention consists in that the pressure foot is pivotably mounted in the recess of a condenser pivotable about the same axis and that this has an opening possesses, into which a guide channel which opens out in principle between the pressing part of the pressing foot and the feed roller of the condenser engages, with a groove at the point where the sliver reaches the combing roller a diameter that tapers in the direction of rotation of the combing roller.

The invention will be made with reference to the accompanying drawings, in which an exemplary embodiment according to the invention is shown, described.

On the pin 5 of the housing 1, the housing of the condenser 6 is pivotably mounted, in its recess 7 on the same pin 5 also pivotable the pressure foot θ with the opening 9t in which the tapering channel 10 of the condenser 6, which opens between the pressure foot θ and the feed roller 4, enters engages} is stored «The pressure foot 8 is secured with the aid of the spring 11 and the pin 12, and also a corresponding one

V fuse element 13 in the housing of the condenser 6 to the Feed roller 4 is resiliently pressed, but without coming into contact with the surface. On the feed roller 4 and the combing roller 2 reaching part of the condenser housing 6 is designed so that this barely as close as possible to these rollers, but without touching them, but with a connecting to the pressure foot θ and in the direction of the feed roller 4 continuously tapering recess is provided and a groove 14 for the controlled delivery of the sliver to the needles 3 of the combing roller 2 and its Yeriichtung forms. The front wall I4I and the upper Wend I42 1st

s * according to the shape of the feed roller 4 and the combing roller 2 and is located close to the surface of the Rollers without coming into contact with them. The recess 7 enables a certain deflection of the pressure foot 8 against the action of the spring 11 and thereby an adaptation of the evenness of the 2 supplied sliver 15

The position of the condenser 6 in relation to the combing roller 2 is through the support surface 16 of the housing 1 of the carding

device determined. The condenser housing 6 is also with a guide channel 17 for the supply of the air flow equipped in the cardiac space 18, namely on the Kind that sioh the mouth of the connecting channel 17 so tight as much as possible or directly on the edge 19, where the recess 14 ends, is »leave after carding the fibers run along the combing device into the spinning chamber 21, into which the fibers are sucked Tangentialkanales 20 and are placed in it on the collecting surface 22 and in the form of a thread 23 through the Fadenaus outlet opening 24 and wound onto the bobbin 25. The feed roller 4 is close to the combing roller 2 attached without touching it. This enables efficient cleaning of the feed roller 4 directly achieved by the combing roller 2

If some of the carding device is necessary, the securing element 13 is loosened and the condenser housing 6 is opened, whereby the operator can access the groove I4, the feed ^{roller 4 and} the combing roller 2 can be inserted between the pressure foot 8 and the feed roller 4.

The invention of course also includes the application a combing device with a so-called direct guide channel in which to the active surface of the combing roller a stream of air from the environment to achieve a more efficient doffing and carding of the fiber material is fed, not off. ·
