Problems solved by technology

Therefore, it is easy to happen that various influencing factors cannot be fully coordinated, so that the structure of the produced fancy yarn is greatly different from the predetermined structure of the fancy yarn
Changes in the spinning adjustment based on the visual acceptance check of the yarn often lead to expensive and very time-consuming coordination operations

Embodiment Construction

[0029] A single spinning station 1 of a large number of spinning stations of an air spinning machine is shown in side view. At the spinning station 1 , the fiber ribbon 3 is drawn from the fiber ribbon tank 2 via a so-called yarn collector 4 into the spinning box 5 of the rotor spinning unit. The mechanism arranged in the spinning box 5 for separating the fibers and supplying them to the spinning rotor 6 is known from the prior art and will therefore not be described in more detail. The drive of the spinning cups 6 is shown, comprising a belt 7 running along the machine, by means of which the spinning cups of all the spinning stations mounted on one longitudinal side of the spinning machine are driven. Alternatively, however, the spinning rotor can also have a single drive. The belt 7 rests on the rotor shaft 8 of the rotor 6 .

[0030] The yarn 9 drawn off by the withdrawal roller 11 through the yarn withdrawal tube 10 is formed in the spinning cup 6 . The yarn 9 then pass...

Abstract

The invention relates to a method of improving the conformity between produced fancy yarns and a predetermined structure of said fancy yarns. According to the method according to the invention, after the effect yarn has been formed, it is guided through a sensor device in the spinning device, and the diameter of the effect yarn is continuously measured by the sensor device. The effect of the produced yarn is determined from the measured diameter and compared with a predetermined effect. The comparison is carried out until a sufficient agreement is obtained between the predetermined effect and that of the optimally produced yarn.

Description

technical field [0001] The invention relates to a method for producing fancy yarns according to the preamble of claim 1 . Background technique [0002] A yarn having a predetermined larger diameter and a predetermined length of thick location (ie, a so-called effect) is called a fancy yarn. The portion of the yarn with a smaller diameter (in other words, the non-effect portion) located between the slubs is called the warp (web). The effect data determining the effect yarns specifically include effect length, effect diameter, effect frequency and the corresponding non-effect yarn length or warp length. [0003] Fancy yarns are becoming more and more important. Fields of application are, for example, denim materials, materials for casual wear and household textiles. [0004] Fancy yarns can also be produced on open-end spinning machines. In this case, the fibers fed to the opening rollers of the air spinning mechanism vary, for example due to changes in the rotational spee...
