The invention relates to a device, in particular for use in a warping machine, for guiding threads which are guided parallel in a plane and which are to be wound onto a thread lap at the same time. Such a device comprises a guide element which is provided with a series of side-by-side openings through which the threads of the plane run, furthermore a drive means which can communicate at least one corrective movement to the guide element, at least part of which is the result contained in the plane of the a "tu their transverse movement aueführt.

display elements are also provided which, in cooperation with selvedge or edge threads, supply the drive means with a control signal which is a function of the edge formation of the thread winding in order to control the drive means in such a way that a deviating edge formation is corrected will.

A device of this type is used to obtain a pape wrap of the same type. This is from ^ of particular importance in the case when twine is used for winding beams

is delivered. In the case of knitting and weaving plants operating from yarn trees, for example, it is necessary that the unwinding of the yarn even at high goech speeds goes smoothly from the trees. Difficulties can arise in particular if there is a poorly aligned level of threads the threads contained in the thread plane next to the tree flanges between and below previously applied turns or winding layers "to be held.

In a known Yorriohtung the type mentioned Aufwick- ¹ * development of yarn on a warp beam, the guide element is formed by a sheet. This sheet includes two sets of parallel wires. The two wire groups are arranged in opposite directions opposite a vertical center line. The plane of the threads can in their entirety - a translational movement in a direction transverse to the front

execute the feed direction of the threads. It is also possible that the parts of the thread plane which are next to its center perform opposite translational movements so that the plane of the threads both widened as well as being narrowed. Which of these translatory movements is to be carried out depends on the edge profile of the yarn tree

from, under which the outline of each end of the tree is to be understood when viewed in a longitudinal section. Venn is required a precisely cylindrical Garnbaum, a deviating edge ä ä training may in a concave or convex edge profile

to express. In the former pail there is a rising edge, in the latter Pail formed a sloping edge. In the known device will .d] he formation of a soft edge profile indicated by elements which provide a signal proportional to the speed of the edge yarn ends. On each side of the the plane receiving the threads are two speed indicators provided which are coupled to the brim and package ends. The signals of the display elements become one Comparison unit supplied in which they are compared. Divides into the pail of a difference between the signals Drive element for the sheet this one corrective movement% with. The drive means comprises a motor which drives the sheet can move horizontally as well as parallel to the axis of the yarn tree, and another motor, which the sheet vertically can move. When the same speed difference is established for the two ends of the yarn tree, only the motor for the vertical blade movement is activated. as

109841/0386

As a result, the plane of the threads is contracted or expanded, depending on whether the sheet is raised or lowered will. If the speed change is only on one At the end of the Bauiaoe appears, the motor is operated, which notifies the sheet of horizontal movement. In this case the plane of the threads moves in their entirety in parallel to the gambaumschso. As a result, the development of the

treatment at the opposite end is influenced accordingly. As a result, the comparison unit is at the latter end the same change in speed. The motor will then actuated for vertical blade movement, as a result of which the edge profile is corrected at both ends. If at the known device there is a poor edge build-up at one end of the thread package, or if there is a rising edge at one end Edge and there is a sloping edge at the other end, a correction is effected in two stages. In the first Stage causes the horizontal blade movement that the same deviation occurs on each side of the thread package. In the second case, the build-up on each side is corrected by the vertical blade movement.

The present invention aims to provide a device in which every type of deviation of the edge structure is corrected in one phase. The device is thereby gekennseichnet that the drive means the guide »element Such a corrective movement communicates that of the edge threads essentially only those which form part of the

form poorly built-up edge, participate in the lateral movement.

The advantage of such a device is that a correction which is transferred to an edge profile that deviates at one end of the yarn tree does not also cause a deviation in the edge profile at the other end of the yarn tree, as is the case with known devices from Pail . The device according to the invention is accordingly in | able to provide a auswahlmäsnige correction of edge profiles throughput similar conduct.

The device according to the invention can be used in various ways be constructed. For example, a sheet with parallel wires can be used as a guide element, which is shown in FIG is able to rotate in its plane around two shafts which are arranged at its ends.

A very suitable and simpler device according to the The invention is characterized in that the guide element is designed in the form of a per se known blade is that the drive means is separated from the blade or

at the same time a translational movement in a direction parallel to the yarn tree axis and a translation movement eenkreoht mx to the yarn tree axis and dad, if both

Translational movements are to be carried out, at the same time the direction of the resulting translation is the same as the direction of a blade opening through which an edge thread runs.

The structure of the display element 11 (see T'lg. 2 and 3) is completely symmetrical with that of the insöigsslementss H, so that only the display element 11 is covered. A first outflow passage 19 is provided on a door surface 18 of the display panel 11, which communicates with a connection port 22 via bores 20 ₉ 21, and a second outflow passage 23 is provided in a side surface 24, which lies against the splash 8. A third outflow passage 25 is. arranged on the Yorderflache on the right. The wide and third outflow passages are both with a bore 29 via bores 27 Os'. = ?. 28 in connection. The bore 29 is in communication with a connecting piece. Geraäss Pig. 1 are the connecting pieces 22, with a distribution line 33 baw. 34 connected by a flexible line 31 and 32, respectively. In the same way, the display element 14 is connected to the distribution lines 33 * 34 by flexible lines 35 »36. Compressed air at a pressure of 2 atmospheres is introduced into the manifold lines through inlet tubes 37, 38. In these distribution lines the air flow splits into two partial flows, each of which runs through a fixed constriction 39, 40, 41, 42. The compressed air then runs through the flexible lines 31, 32 and 35, into the display elements 11 and 14, respectively. The passage for the compressed air between the inlet pipes 37, 38 and the outlet

109841/0386

passage through the display elements 11, 14- is referred to below as ale main channel. Thus, the inlet pipe 37, the .liner half of the distribution line 33, ^the flexible line 3.1 j the connecting pipe 22 and the bores 20, 21 (Pig, 2) form a main channel through which compressed air is led to the first outflow passage 19. Another The main channel is formed by the inlet pipe 38, the left half of the distribution line 34 _y the flexible line 32, the connecting pipe 30 and the bores 29, 2-7, the compressed air being fed through this main channel to the second outlet passage 23. Corresponding main channels connect the Inlet pipes 37, 38 with the outflow passages of the display element 14 ο Two auxiliary channels end in each of these two distribution lines, which are connected at their other ends to a drive means for the blade 3 explained below of the distribution line 33. These two auxiliary channels around- <| grasp a connecting pipe 43 or 44 and a flexible managerial ä tung 45 and 46. The lines 45, 46 are connected to pressure switches 47, 48 connected, which are each provided with two contacts and have a neutral center position. The pressure switches are electrically connected to two polarized relays 49, 50, the contacts of which are used to control synchronous motors 53, 54 via schematically indicated electrical connections 51, 52. The synchronous motors form part of a drive device for daaPlügelblßtt 3, which in a

109841/0386

zontal direction parallel to the axis of the calf pad 7 can be deflected by the synchronous motor 53 and in the vertical direction KU of this axis by the synchronous motor 54 is.

In the following it is assumed that only a convex edge profile occurs. The drive device works here, as will be explained below, in such a way that when the convexity of the edge profile falls below a given value, which is referred to below as the lower limit is, a correction is carried out, which has the consequence that an edge profile with a greater convexity is being built. On the other hand, when the convexity has exceeded a given value, which is hereinafter referred to as upper limit "causes the resulting correction an edge structure with less convexity .;

For example, when the left edge profile exceeds the upper limit, the following processes take place: When the compressed air leaves the left display element 1s through the outflow passage 19, a relatively low resistance occurs. As a result, the air pressure falls in the auxiliary channel 4- "5". 45.. The pressure switch 47 closes on it, one of its two contacts are energized so that the polarized relay 49, 50, when actuated, the contacts set AEOA polarized relay the synchronous motors 53, in operation, "which gives the blade a horizontal baw.

The speeds of this translational movement are of such magnitude and direction that the resulting blade movement takes place in a downward direction _? . which parallel'zu the direction dee right "Flügelblattclurehtrittes is through which an edge thread = extends in the present case this is the Flügelblattdurcbtritt at the aussar3t right. As a consequence, deflect the 'left edge threads to the left, while the right -Randfäde-n in remain their position. the convexity of the left edge profile is thus reduced It is to be repeated in this connection that in the case of a convex or falling Randprofila the maximum deviation is only einigenfehntelmillimetsrn in the large array of "this variation relates to the difference in the radius of a weak from Cylindrical shape deviating yarn package compared to an exactly cylindrical yarn package.

In the opposite case, the convexity of the left edge profile decreases, the outflow passage 19 is increasingly reduced, so that the pressure in the auxiliary channel 4-5 '»45 increases. When this pressure exceeds a predetermined maximum value corresponding to the lower limit of the convexity, the pressure switch closes 47 its other contact, the polarized relays 49, 50 are then traversed in the opposite direction of flow, after which the Synqhronmotoren 53, 50 start to rotate in the opposite direction,

109841/0386

The blade 3 is then in the opposite direction ;? Ausslenlrfc direction, that means near top right = so that the left edge threads are printed to the right. If the deviations only occur on the right edge profile, an analogous correction is made with the exception that the wing blade is moved in a direction parallel to the wing blade diameter on the extreme left side,

fc If similar deviations occur on both sides of the calf pad, the wing blade is only moved in the vertical direction. If an excessively convex edge profile occurs on both sides, the air pressure in the two auxiliary channels 43, 45 and 44, 46 falls to one value at which the two pressure switches close one of their contacts. The switching state is such that the polarized relay 50 is excited, whereas the resulting excitation of the polarized relay 49 is zero.

The synchronous motor 54 then steers the blade 3 vertically down so that both the left and the right Edge threads are moved outwards.

On the other hand, when opposite deviations occur at both ends, the blade is moved in a horizontal direction. If, for example, the left edge profile is too weakly convex, but the right edge profile is too strongly convex, the polarized relay 49 is excited, but the

As a result, only the synchronous motor 53 energizes -'excites' and drives the leaf with the entire array of threads horizontally to the right To obtain a sensitive control over a relatively large area is preferable, because the ratio of the cross-sectional area of the first external passage to that of the associated Terengimg corresponds approximately to the value two.

In this case, the air pressure in the common auxiliary channel drops as soon as an additional outflow passage of one of the display elements is concluded to have a lower operating value.

It turned out to be advantageous to equip each control loop with a PD controller (proportional / differential controller) in this Pail be coupled to the pressure roller, so that no separate sensing element needs to be provided. The corner of such a pressure roller is to achieve a smooth thread winding. However, the use of such a pressure roller has the! The pressure roller and the steep winding cannot be kept exactly the same. Therefore, a slippage occurs, which can lead to the formation of flakes and tearing of the threads. An attempt can now be made to produce a smooth thread winding without using a pressure roller by inserting the sheet into a direction parallel to the axis of the filament winding a periodic transverse movement using a corresponding transverse stroke is issued with an adapted frequency. Such a transverse movement can be superimposed on the correction movements described above. This is preferably achieved electrically by superimposing an electrical transverse deflection signal on electrical control signals for the blade motors 53, 54. Such an overlay is elec-
