GERMAN Company LANDGRAFENSTRASSE 45, D-41069, MONCHENGLADBACH, GERMANY PREAMBLE TO THE DESCRIPTION The following specification particularly describes the invention and the manner in which it is to be performed : - Description The invention relates to a method according to the preamble of claim 1. When producing yarn, a uniformity of the yarn, which is as high as possible, is generally aimed for within narrow tolerances. On the other hand, the non-uniformity of the yarn is characteristic of fancy yarns. A yarn, in which thick locations with predetermined larger diameters and with predetermined lengths, the so-called effects, are present, are referred to as fancy yarns. The yarn sections located there between with a smaller diameter are referred to as webs. It is known to carry out a diameter average value determination at the beginning of measuring at a spinning station, over the first yarn meter. This so-called reference diameter is the reference diameter for further evaluations. In the case of a fancy yarn, a reference diameter determined in this manner would be indicated to be thicker owing to the presence of effects, in other words thick locations, than the thickness of the web actually is. The recognition of the formation of effects is only possible on this basis of a simple averaging to an inadequate degree. DE 100 26 389 Al describes a device for monitoring a running thread by means of a sensor mechanism of a spinning unit. If the value of the diameter exceeds selected tolerance limits over a predetermined length, the beginning of a fault location in the thread is inferred. If the value of the diameter then moves for a corresponding length again within the tolerance zone/ the end of the fault location is inferred. In the process, each of these exceedings of a tolerance is classified as a yarn fault. The diameter values detected consecutively on the running thread are detected as a curve course over the yarn length and the curve is filed in a data memory. The data memory contains predetermined curve course patterns, which represent a section of the curve course in the area of a fault location, as pattern types. These pattern types allow conclusions about the causes of the fault on the basis of the formation of their curve course. In order to establish whether a predetermined pattern type is repeated in the curve course, the curve course is compared with the predetermined pattern types. If, in the process, it is recognised in the curve course, that a fault location corresponds to a pattern type, the type of the fault and cause of the fault are determined with the aid of the recognised pattern type and elimination thereof is triggered. Although it is possible to improve the determination and quality of statements about faults and causes of faults with the device of DE 100 26 389 Al, it is not possible to adequately monitor on the running thread whether the diameters of effects are formed as desired. The object of the invention is to improve the determination of effects of a fancy yarn. This object is achieved by a method with the features of claim 1. Advantageous configurations of the invention are the subject of the sub-claims. The method according to the invention makes it possible to recognise the effects better and to determine the effect diameter, also referred to as the effect thickness, and the effect length more correctly. The web diameter, also called the web thickness, can be determined according to claim 3 largely uninfluenced by the effects and therefore substantially more accurately, than is possible with the known simple reference value formation in yarn measurements. This increased accuracy also has a positive effect on the accuracy of the effect determination. It can be avoided with a method according to claim 4 that only a very brief exceeding or falling below of the limit diameter leads to a falsification of the effect length. A variation value is advantageously determined, which provides the variation of the diameter over the effect length. For this purpose, the diameter is continuously measured within the effect length. The variation value can be provided as the average quadratic non-uniformity that provides information about the uniformity of the effect course. Conclusions about the quality of the subsequent end product, for example a fabric, can be drawn from the variation value. A high uniformity allows a clean image of the effects in the fabric to be expected, a lower uniformity, on the other hand, a blurred image. Determination of the average quadratic non-uniformity corresponds to the known detection of the so-called CV value in the case of smooth yarn. The method according to the invention allows detection of the effect length and effect thickness with values, which very closely approach the real configuration and therefore allow reliable information about the quality of the fancy yarn and the end product. Further details of the invention can be found in the figures. In the figures: Fig. 1 shows a device for carrying out the method according to the invention, Fig. 2 shows a fancy yarn, which is shown by arranging measured values of the yarn diameter side by side, Fig. 3 shows a schematic diagram of a yarn effect. Fig. 1 shows a section of a fancy yarn 1, which runs through a sensor 2, which is provided to measure the yarn diameter D. The sensor 2 is an optical sensor, as is known in principle, and which will not therefore be described in detail here. The sensor 2 is connected via a line 3 to the evaluation unit 4. The evaluation unit 4 determines the desired effect data from the measured values of the yarn diameter D transmitted by the sensor 2. The evaluation unit 4 transmits the effect data via the line 5 to an output mechanism comprising a monitor 6. The effect data can be shown in the desired form on the monitor 6. The evaluation unit 4 is connected via the lines 1 to further evaluation units or computers, not shown. jig. 2 shows the view of the fancy yarn 1, as measured values arranged side by side. Effects 8 and webs 9 can be seen but the beginning and end of the effects 8 and the effect thickness or the effect diameter Dg and the web thickness or the web diameter DST cannot be recognised clearly and therefore not adequately. The evaluation unit 4 registers the yarn diameter D after 2 mm yarn length, in each case. A cycle represents a measuring length of 2 mm yarn. In the view of Fig. 3, the yarn diameter D is shown in a percentage over the yarn length LG as a curve 10. The curve 10 represents the web diameter DST in the view of Fig. 3 beginning from the left up to the point 11. From the point 11 the curve 10 rises and, at point 12, passes the value of the limit diameter DGR. At point 13, the predetermined yarn length Lv2 has been covered since reaching the point 12. After a diameter increase of 15% is registered at point 12, and the exceeding of the limit diameter DGR continues over the predetermined length Lv2, for example for six cycles or 12 mm, the point 12 is defined as the beginning of the effect. The curve 10 falls below the limit diameter DGR at the point 14. The falling below last until point 15 and therefore over the predetermined yarn length Lv2 Therefore, the point 14 is defined as the end of the effect. The effect length LE is determined from the beginning and end of the effect between point 12 and point 14. An arithmetic average is formed from the four largest diameters 16 within the effect. The provision of the effect diameter is therefore largely independent of the natural diameter variations in the effect area. This arithmetic average is defined as the effect diameter Dg. A variation value, which makes a statement about the quality of the effects 8 possible, is determined on the basis of the variations of the yarn diameter D, which can be recognised in Figs. 2 and 3, in the area of the effect length of the effects 8. The variation value provides the average quadratic non- uniformity and is a measure of the uniformity of the effect course. The higher the uniformity of the effect course, the better the quality of the fancy yarn 1 and the end product produced therefrom, for example a fabric. The variation value is the relative dispersion of the individual values around the average of the yarn diameter D within the effect length. Further configurations of the method within the scope of the invention are possible. The method according to the invention We Claims: 1.

PREAMBLE TO THE DESCRIPTION
The following specification particularly describes the invention and the manner in which it is to be performed : -

Description
The invention relates to a method according to the preamble of claim 1.
When producing yarn, a uniformity of the yarn, which is as high as possible, is generally aimed for within narrow tolerances. On the other hand, the non-uniformity of the yarn is characteristic of fancy yarns. A yarn, in which thick locations with predetermined larger diameters and with predetermined lengths, the so-called effects, are present, are referred to as fancy yarns. The yarn sections located there between with a smaller diameter are referred to as webs.
It is known to carry out a diameter average value determination at the beginning of measuring at a spinning station, over the first yarn meter. This so-called reference diameter is the reference diameter for further evaluations. In the case of a fancy yarn, a reference diameter determined in this manner would be indicated to be thicker owing to the presence of effects, in other words thick locations, than the thickness of the web actually is. The recognition of the formation of effects is only possible on this basis of a simple averaging to an inadequate degree. DE 100 26 389 Al describes a device for monitoring a running thread by means of a sensor mechanism of a spinning unit. If the value of the diameter exceeds selected tolerance limits over a predetermined length, the beginning of a fault location in the thread is inferred. If the value of the diameter then moves for a corresponding length again within the tolerance zone/ the end of the fault location is inferred. In the process, each of these exceedings of a tolerance is classified as a yarn fault. The diameter values detected consecutively on the running thread are detected as a curve course over the yarn length and the curve is filed in a data memory. The data memory contains predetermined curve course patterns, which represent a section of the curve course in the area of a fault location, as pattern types. These pattern types allow conclusions about the causes of the fault on the basis of the formation of their curve course. In order to establish whether a predetermined pattern type is repeated in the curve course, the curve course is compared with the predetermined

pattern types. If, in the process, it is recognised in the curve course, that a fault location corresponds to a pattern type, the type of the fault and cause of the fault are determined with the aid of the recognised pattern type and elimination thereof is triggered. Although it is possible to improve the determination and quality of statements about faults and causes of faults with the device of DE 100 26 389 Al, it is not possible to adequately monitor on the running thread whether the diameters of effects are formed as desired.
The object of the invention is to improve the determination of effects of a fancy yarn.
This object is achieved by a method with the features of claim 1. Advantageous configurations of the invention are the subject of the sub-claims.
The method according to the invention makes it possible to recognise the effects better and to determine the effect diameter, also referred to as the effect thickness, and the effect length more correctly.
The web diameter, also called the web thickness, can be determined according to claim 3 largely uninfluenced by the effects and therefore substantially more accurately, than is possible with the known simple reference value formation in yarn measurements. This increased accuracy also has a positive effect on the accuracy of the effect determination.

A variation value is advantageously determined, which provides the variation of the diameter over the effect length. For this purpose, the diameter is continuously measured within the effect length. The variation value can be provided as the average quadratic non-uniformity that provides information about the uniformity of the effect course. Conclusions about the quality of the subsequent end product, for example a fabric, can be drawn from the variation value. A high

uniformity allows a clean image of the effects in the fabric to be expected, a lower uniformity, on the other hand, a blurred image. Determination of the average quadratic non-uniformity corresponds to the known detection of the so-called CV value in the case of smooth yarn.
The method according to the invention allows detection of the effect length and effect thickness with values, which very closely approach the real configuration and therefore allow reliable information about the quality of the fancy yarn and the end product.
Further details of the invention can be found in the figures.
In the figures: Fig. 1 shows a device for carrying out the method according to
the invention,
Fig. 2 shows a fancy yarn, which is shown by arranging measured values of the yarn diameter side by side,
Fig. 3 shows a schematic diagram of a yarn effect.
Fig. 1 shows a section of a fancy yarn 1, which runs through a sensor 2, which is provided to measure the yarn diameter D. The sensor 2 is an optical sensor, as is known in principle, and which will not therefore be described in detail here. The sensor 2 is connected via a line 3 to the evaluation unit 4. The evaluation unit 4 determines the desired effect data from the measured values of the yarn diameter D transmitted by the sensor 2. The evaluation unit 4 transmits the effect data via the line 5 to an output mechanism comprising a monitor 6. The effect data can be shown in the desired form on the monitor 6. The evaluation unit 4 is connected via the lines 1 to further evaluation units or computers, not shown.

jig. 2 shows the view of the fancy yarn 1, as measured values arranged side by side. Effects 8 and webs 9 can be seen but the beginning and end of the effects 8 and the effect thickness or the effect diameter Dg and the web thickness or the web diameter DST cannot be recognised clearly and therefore not adequately.
The evaluation unit 4 registers the yarn diameter D after 2 mm yarn length, in each case. A cycle represents a measuring length of 2 mm yarn. In the view of Fig. 3, the yarn diameter D is shown in a percentage over the yarn length LG as a curve 10. The curve 10 represents the web diameter DST in the view of Fig. 3 beginning from the left up to the point 11. From the point 11 the curve 10 rises and, at point 12, passes the value of the limit diameter DGR. At point 13, the predetermined yarn length Lv2 has been covered since reaching the point 12. After a diameter increase of 15% is registered at point 12, and the exceeding of the limit diameter DGR continues over the predetermined length Lv2, for example for six cycles or 12 mm, the point 12 is defined as the beginning of the effect. The curve 10 falls below the limit diameter DGR at the point 14. The falling below last until point 15 and therefore over the predetermined yarn length Lv2 Therefore, the point 14 is defined as the end of the effect. The effect length LE is determined from the beginning and end of the effect between
point 12 and point 14. An arithmetic average is formed from the four largest diameters 16 within the effect. The provision of the effect diameter is therefore largely independent of the natural diameter variations in the effect area. This arithmetic average is defined as the effect diameter Dg.
A variation value, which makes a statement about the quality of the effects 8 possible, is determined on the basis of the variations of the yarn diameter D, which can be recognised in Figs. 2 and 3, in the area of the effect length of the effects 8. The variation value provides the average quadratic non- uniformity and is a measure of the uniformity of the effect course. The higher the uniformity of the effect course, the better the quality of the fancy yarn 1 and the end product produced therefrom, for

example a fabric. The variation value is the relative dispersion of the individual values around the average of the yarn diameter D within the effect length.
Further configurations of the method within the scope of the invention are possible. The method according to the invention
