Definitions
- the present invention relates to a spindle for an air-spinning machine according to the preamble of patent claim 1 and a method for setting after a
- Air-jet spinning machines have a multiplicity of spinning stations. In each spinning station, a yarn is spun from a fed longitudinal fiber structure. The fiber longitudinal structure is first refined, that is, the amount of fiber per unit length is reduced by delay. Then the refined fiber strand is spun by twisting into a yarn.
- Spinning a production interruption result The resumption of spinning takes place in such a way that the free yarn end resulting from the interruption is pulled out and positioned beyond the twist distribution point in the opposite direction to the spinning direction - referred to in the jargon as "upstream". Subsequently, the initial region of the fiber structure is overlapped with the free end of the yarn in a known manner in the spinneret by twisting each other and so the spinning process resumed.
- the thread withdrawal channel - also called yarn channel or spindle channel - must have certain dimensions due to spinning and design reasons: Length L:
- the present invention is therefore based on the object for a spinning unit of an air spinning machine to provide a method and a spindle for performing the method, which allow for a disruption of a spinning process safe and precise recycling of the yarn to create a piecing and the spindle structurally simple design should be.
- FIG. 1 Basic illustration of a spindle with an inventive
- FIG. 1a detailed view of a preferred arrangement of an injector channel
- Figure 2 Structural design of a spindle with an injector according to the present invention.
- Figure 1 shows in a principal, not proportionate representation of a rotationally symmetric spindle 10 with a Garnabzugskanal 5.
- the identifier S is the spinning direction in the normal spinning process and the identifier B is the return direction of the spun yarn for yarn breakage indicated.
- a spindle base 2 is arranged with a conical opening at an angle a.
- an injector channel 1 is provided in the spindle 10, the opening of which is arranged in the yarn channel 5 relatively close to the spindle mouth 8.
- a groove 9 is turned out.
- the diameter di of the cylindrically shaped injector channel 1 lies in the following value range: 0.5 mm ⁇ di ⁇ 0.7 mm; preferably 0.6 mm.
- FIG. 1 a shows a preferred embodiment of the arrangement of the injector channel 1.
- the axis 7.1 of the injector 1 and the axis 7.2 of the yarn channel 5 intersect approximately at the spindle mouth 8.
- the inclination angle ß of the two aforementioned axes is preferably in a range of 5 ° - 20 °. In this preferred embodiment with the intersection of the two axes, the following optimum value results for the distance D:
- the relation between the aforementioned distance D and the length L of the spindle is: D «L, where D ⁇ 8mm, more preferably D ⁇ 5mm.
- Figure 2 shows a preferred structural configuration of the spindle 10 with the inventive arrangement of an injector 1:
- the spindle 10 is formed with two connected via a fit 6 parts 10.1 - also called spindle tip 10.1 - and 10.2 - also called spin tube 10.2.
- the injector 1 has two parts 1.1 and 1.2, which are axially inclined to each other and differ in their di and di di 2 : ⁇ 2 > di and ⁇ 2 ⁇ 1.5mm ⁇ 0.5 mm.
- the spindle tube 10.2 can be processed with the larger diameter pursuer 2 easier and thus manufactured more cost-effectively.
- both injector 1.1 and 1.2 can be relatively easily created as bores 1.1 and 1.2 of the separation surface F.
- the diameter d ⁇ of the inlet opening and the inner diameter di are preferably in the following ratio: 0.3 ⁇ - ⁇ - ⁇ 0.8. d ⁇
- the two parts 10.1 and 10.2 are preferably glued together for connection.
- the part 10.1 or the spindle tip in the region of the connection to the spindle tube 10.2 has an annular gap 12 in a preferred embodiment.
- the yarn channel 5 has a conical shape 4 within the part 10.1.
- the conical shape 4 is determined by the cone length K and the diameters d A and d E. K has a typical value of about 20 mm ⁇ 7 mm.
- the method of setting includes: The yarn end of the yarn is initiated backwards by a corresponding actuation of the supply of compressed air into the groove 9. According to the Bernoulli law, a negative pressure or a suction effect is created on the spinning base 2, so that the yarn end passes through the yarn channel 5 via the
- Spindle muzzle 8 can move out.
- the teaching according to the invention can be realized by a free combination of the structural configurations and dimensions explained above in FIGS. 1, 1a and 2, for example the diameters of the injector channels 1.1 and 1.2 are largely independent of the configuration of the cone of the thread withdrawal channel 5 or of the cone of the Spindle bases 2.
