Problems solved by technology

However, if there are fancy yarns produced, for example, on a ring spinning machine, but are now to be produced on an open-end spinning machine with approximately the same pattern specification, the patterns and settings available cannot be transferred directly data

Embodiment Construction

[0026] Among the numerous spinning stations of the rotor spinning machine, a single spinning station 1 is shown in side view. At the spinning station 1 , the fiber ribbon 3 is drawn from the fiber ribbon tank 2 into the spinning box 5 of the rotor spinning unit by means of a so-called compressor 4 . The mechanisms provided in the spinning box 5 for separating the fibers and feeding them into the spinning rotor 6 are known from the prior art and will therefore not be described in more detail. Briefly explain the drive of the spinning cups 6, which consists of a belt 7 extending along the machine, through which all spinning cups of a spinning station mounted on the longitudinal sides of the spinning machine are driven. Alternatively, however, a separate drive can also be provided for the spinning rotor. The belt 7 is located on the cup shaft 8 of the spinning rotor 6 .

Abstract

The purpose of the present invention is to create a method that enables the reproduction of previously produced fancy yarns. Said object is achieved by the following methods: firstly, a standard fancy yarn is guided through a sensor device for measurement; the diameter of the standard fancy yarn is continuously measured by said sensor device; the measured diameter value is evaluated , and determine the pattern composition of the standard fancy yarn from it. Spinning settings are generated from data representative of pattern composition and fancy yarns are produced using said spinning settings based on a set of said data.

Description

technical field [0001] The invention relates to a method for producing fancy yarns according to the preamble of claim 1 and a device according to claim 14 . Background technique [0002] A yarn with a predetermined larger diameter and a predetermined length of thick locations (ie, a so-called effect) is called a fancy yarn. The part of the yarn in the middle with a smaller diameter (in other words, the non-effect part) is called the warp (web). Fancy yarns are becoming more and more important. Fields of application are, for example, denim, materials for casual wear and household textiles. [0003] Fancy yarns can also be produced on open-end spinning machines. In this case, the fibers delivered to the opening rollers of the air spinning mechanism vary, for example due to changes in the speed of the feed rollers. To this end, mechanical transmissions are actuated, which drive shafts extending along the length of the machine. These feed rollers are rotated by the shaft. ...
