Description

Die Erfindung betrifft ein Verfahren zum Einstellen und Verbinden von Streckwerken einer Einkopf- oder Zweikopfstrecke, wobei jedes der Streckwerke in Lagerböcken abgestützte Streckwerkswalzen und bei einer Zweikopfstrecke daran angeordnete und miteinander verbundene Wellen aufweist. Die Erfindung betrifft weiterhin eine Strecke mit einem Gestell mit wenigstens einem Streckwerk, das über Lagerböcke auf dem Gestell angeordnet ist.The invention relates to a method for setting and connecting drafting devices of a single-head or two-head draw frame, wherein each of the drafting devices has drafting device rollers supported in bearing blocks and shafts arranged thereon and connected to one another in a two-head draw frame. The invention further relates to a line with a frame with at least one drafting system, which is arranged on the frame via bearing blocks.

Bekannt sind Einkopfstrecken, d.h. Strecken, welche ein einziges Streckwerk zum Verzug von Faserbändern verwenden, bei welchen die Streckwerkswalzen in Lagerböcken direkt auf dem Gestell der Strecke befestigt sind. Zur horizontalen und vertikalen Ausrichtung des Streckwerkes, bzw. der Lagerböcke auf dem Gestell, werden Distanzscheiben zwischen den Lagerböcken und dem Gestell mit einer Dicke angeordnet, welche das Streckwerk in die gewünschte Lage hebt. Für eine ordnungsgemäße Ausrichtung des Streckwerks werden unterschiedliche Dicken der Distanzscheiben gewählt. Diese Montage ist zeitaufwendig, da bei einer nicht richtigen Wahl der Distanzscheiben die Lagerböcke wieder demontiert und mit einer veränderten Höhe der Distanzscheiben wieder neu montiert werden müssen.Single-head draw frames are known, ie draw frames which use a single drafting arrangement for drawing fiber slivers, in which the drafting arrangement rollers are fastened in bearing blocks directly on the frame of the draw frame. For horizontal and vertical alignment of the drafting system, or the bearing blocks on the frame, spacers are arranged between the bearing blocks and the frame with a thickness which lifts the drafting system into the desired position. Different thicknesses of the spacers are selected for proper alignment of the drafting system. This assembly is time-consuming, since if the spacers are not selected correctly, the bearing blocks must be dismantled again and reassembled with a changed height of the spacers.

Weiterhin bekannt ist eine Zweikopfstrecke, d.h. eine Strecke, bei welcher zwei parallel zueinander angeordnete Streckwerke den Verzug von Faserbändern bewirken. Neben der Ausrichtung der einzelnen Streckwerke, ähnlich wie bei der Einkopfstrecke, ist es weiterhin erforderlich, die beiden parallelen Strecken genau zueinander fluchtend auszurichten. Dies ist erforderlich, da die beiden Streckwerke üblicherweise über einen einzigen Antrieb angetrieben werden und somit die einander entsprechenden Streckwerkswalzen der beiden Streckwerke miteinander starr verbunden sind. Für diese starre Verbindung der Streckwerkswalzen ist es erforderlich die beiden Streckwerke sowohl in vertikaler als auch in horizontaler Richtung in Übereinstimmung zu bringen, so daß die Wellen der Streckwerkswalzen miteinander verbunden werden können.A two-head section is also known, i.e. a route in which two drafting systems arranged parallel to one another cause the warping of fiber slivers. In addition to the alignment of the individual drafting systems, similar to the single-head draw frame, it is also necessary to align the two parallel draw frames exactly in line with one another. This is necessary because the two drafting systems are usually driven by a single drive and the corresponding drafting system rollers of the two drafting systems are thus rigidly connected to one another. For this rigid connection of the drafting rollers, it is necessary to bring the two drafting systems into alignment, both in the vertical and in the horizontal direction, so that the shafts of the drafting rollers can be connected to one another.

Aufgabe der vorliegenden Erfindung ist es nunmehr ein Verfahren und eine Vorrichtung zu schaffen, mit welcher die Montage der Streckwerke einer Strecke schnell und kostengünstig, sowie lagegenau positioniert durchgeführt werden kann.The object of the present invention is now to provide a method and a device with which the assembly of the drafting systems of a route can be carried out quickly and inexpensively, as well as being positioned precisely.

Die Aufgabe wird gelöst durch die Merkmale der Ansprüche 1, 3 und 5. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen beansprucht.The object is achieved by the features of claims 1, 3 and 5. Advantageous embodiments of the invention are claimed in the subclaims.

Wird der Lagerbock auf einem Tisch angeordnet und mittels erster Stellmittel die Höhe und mittels zweiter Stellmittel die Neigung des Tisches gegenüber dem Gestell eingestellt, so ist die Justierung des Lagerbocks des Streckwerkes einfach und schnell durchzuführen. Eine mehrmalige Demontage des Lagerbocks zum Unterlegen unterschiedlicher Distanzscheiben solange, bis die Höhe und Neigung des Lagerbocks in Bezug auf die übrigen Bauteile der Strecke ordnungsgemäß ist, wird dadurch vermieden. Durch die Verstellung der Stellmittel solange, bis die gewünschte Lage erreicht ist, wird die Montage wesentlich vereinfacht.If the bearing block is arranged on a table and the height is adjusted by means of the first adjusting means and the inclination of the table relative to the frame by means of the second adjusting means, the adjustment of the bearing block of the drafting arrangement can be carried out simply and quickly. Repeated dismantling of the pedestal for support different spacers until the height and inclination of the pedestal is correct in relation to the other components of the route is avoided. The adjustment is considerably simplified by adjusting the adjusting means until the desired position is reached.

In einer vorteilhaften Ausgestaltung wird die horizontale Ausrichtung der Lagerböcke mittels Einstellmittel gegenüber dem Tisch eingestellt. Daraus ergibt sich der Vorteil, daß die Lagerböcke nach der lagerichtigen Einstellung des Tisches in ihrer horizontalen Lage auf dem Tisch verändert werden können.In an advantageous embodiment, the horizontal alignment of the bearing blocks is adjusted relative to the table by means of adjusting means. This has the advantage that the bearing blocks can be changed in their horizontal position on the table after the table has been set in the correct position.

Besonders vorteilhaft ist die erfindungsgemäße Vorrichtung bei einem Verfahren zum Einstellen und Verbinden von Streckwerken einer Zweikopfstrecke anwendbar. Werden die Lagerböcke der Streckwerkswalzen auf einem Tisch angeordnet, so kann mittels erster Stellmittel die Höhe des Tisches gegenüber dem Gestell eingestellt werden und mittels zweiter Stellmittel die vertikale Ausrichtung der Wellen so lange verändert werden, bis sie vertikal fluchtend einander gegenüberstehen. Mittels der ersten Stellmittel wird die Sollhöhe des Streckwerkes eingestellt, damit die Faserbänder, welche das Streckwerk durchlaufen, ohne Umlenkung von den vor dem Streckwerk angeordneten Bauteilen an das Streckwerk und aus dem Streckwerk an die dem Streckwerk nachgeordneten Bauteile übergeben werden.The device according to the invention can be used particularly advantageously in a method for setting and connecting drafting devices of a two-head draw frame. If the bearing blocks of the drafting rollers are arranged on a table, the height of the table relative to the frame can be adjusted by means of first adjusting means and the vertical alignment of the shafts can be changed by means of second adjusting means until they are aligned vertically with one another. The setpoint height of the drafting system is set by means of the first adjusting means so that the fiber slivers which pass through the drafting system are transferred without deflection from the components arranged in front of the drafting system to the drafting system and from the drafting system to the components downstream of the drafting system.

Für eine zusätzliche horizontale Ausrichtung der Wellen zueinander ist es vorteilhaft, wenn mittels weiterer Einstellmittel die Lagerböcke der Streckwerke so zueinander verändert werden, bis die Ausrichtung der Wellen derart ist, daß sie horizontal einander gegenüberstehen. Nach dieser Einstellung können die Wellen der Streckwerkswalzen mittels einer Kupplung weitgehend spannungsfrei verbunden werden.For an additional horizontal alignment of the shafts to one another, it is advantageous if the bearing blocks of the drafting units are changed relative to one another by means of further adjusting means until the alignment of the shafts is such that they are horizontal to one another face each other. After this setting, the shafts of the drafting rollers can be connected largely without tension by means of a coupling.

Ist zur Lageeinstellung der Lagerböcke, auf welchem die Streckwerkswalzen des Streckwerkes gelagert sind, zwischen den Lagerböcken und dem Gestell ein Tisch angeordnet, so ist vorteilhafter Weise die Justierung der Lagerböcke schnell, einfach und genau durchführbar. Die Lagerböcke müssen zur genauen Lageeinstellung nicht demontiert werden, wenn der Tisch mittels Stellschrauben mit dem Gestell verbunden ist.If a table is arranged between the bearing blocks and the frame for the position adjustment of the bearing blocks on which the drafting unit rollers of the drafting unit are mounted, then the adjustment of the bearing blocks can advantageously be carried out quickly, easily and precisely. The pedestals do not have to be dismantled for precise position adjustment if the table is connected to the frame using set screws.

Besonders vorteilhaft ist es, wenn mit Hilfe des Tisches die Höheneinstellung, sowie die vertikale Ausrichtung der Lagerböcke durchführbar ist. Dadurch ist eine genaue Einstellung des Streckwerkes, insbesondere dann, wenn es sich um eine Zweikopfstrecke handelt, bei welcher zwei Streckwerke zueinander ausgerichtet werden müssen, vorteilhaft.It is particularly advantageous if the height adjustment and the vertical alignment of the bearing blocks can be carried out using the table. As a result, a precise adjustment of the drafting arrangement is advantageous, in particular when it is a two-head draw frame in which two drafting arrangements have to be aligned with one another.

Für die horizontale Einstellung der Lagerböcke werden diese mittels exzentrischer Bundbolzen auf dem Tisch eingestellt. Der Vorteil dabei ist, daß die vertikale Ausrichtung der Lagerböcke bereits erfolgt ist und somit durch eine Verstellung der exzentrischen Bundbolzen lediglich eine horizontale Einstellung erfolgt. Durch diese Trennung der horizontalen und vertikalen Einstellbarkeit der Lagerböcke, ist eine schnelle und zuverlässige Justierung der Lagerböcke und damit der Streckwerke gewährleistet.For the horizontal adjustment of the pedestals, these are adjusted on the table using eccentric collar bolts. The advantage here is that the vertical alignment of the pedestals has already taken place and thus only horizontal adjustment is made by adjusting the eccentric collar bolts. This separation of the horizontal and vertical adjustability of the pillow blocks ensures quick and reliable adjustment of the pillow blocks and thus the drafting units.

Besonders vorteilhaft ist es, wenn der Lagerbock zwei Bundbolzen aufweist, wobei einer exzentrisch und der andere rund ist. Dabei kann durch Verdrehung des exzentrischen Bundbolzens der Lagerbock um den runden Bundbolzen gedreht werden, wodurch eine gute horizontale Einstellung des Lagerbocks auf dem Tisch gewährleistet wird.It is particularly advantageous if the bearing block has two collar bolts, one being eccentric and the other round. Here the bearing block can be rotated around the round flange bolt by turning the eccentric flange bolt, which ensures a good horizontal adjustment of the bearing block on the table.

a plan view of a two-head line.

In Figur 1 ist eine Vorderansicht einer Einkopfstrecke 1 dargestellt. Die Strecke 1 weist als tragendes Bauteil ein Gestell 2 auf. Auf diesem Gestell 2 sind die verschiedenen Funktionsbaugruppen der Strecke 1, wie z.B. Regelungseinrichtungen, Motor, Abzugswalzen und Faserbandablageeinrichtungen angeordnet. Darüberhinaus ist auf dem Gestell 2 ein Tisch 10 befestigt, welcher einen Lagerbock 4 mit Streckwerkswalzen 5 trägt. Lagerbock 4 mit Streckwerkswalzen 5 bilden ein Streckwerk 3.1 shows a front view of a single-head section 1. The route 1 has a frame 2 as a load-bearing component. On this frame 2 are the various functional modules of section 1, such as Control devices, motor, take-off rollers and sliver storage devices arranged. In addition, a table 10 is attached to the frame 2, which carries a bearing block 4 with drafting rollers 5. Bearing block 4 with drafting system rollers 5 form a drafting system 3.

Der Tisch 10 ist mittels Stellschrauben 11 und 12 auf dem Gestell 2 befestigt. Auf dem Tisch 10 ist das Streckwerk 3 mittels einem exzentrischen Bundbolzen 15 und einem runden Bundbolzen 16 justiert. Die Befestigung des Streckwerks 3 auf dem Tisch 10 kann zusätzlich mittels Schrauben erfolgen.The table 10 is fastened to the frame 2 by means of set screws 11 and 12. The drafting system 3 is adjusted on the table 10 by means of an eccentric collar bolt 15 and a round collar bolt 16. The drafting device 3 can also be attached to the table 10 by means of screws.

Für eine Einstellung des Streckwerks 3 hinsichtlich seiner Höhe, Neigung und Position, bezüglich der übrigen Bauteile der Strecke 3 wird folgendermaßen verfahren. Das Gestell 2 wird auf dem Boden der Halle, in welcher die Strecke aufgestellt werden soll befestigt. Eine genaue Höhenjustierung des Gestells 2 ist dabei nicht erforderlich. Die genaue Einstellung wird über den Tisch 10 durchgeführt. Der Tisch 10 wirkt dabei als Justierplattform für das Streckwerk 3. Der Tisch 10 ist über die Stellschrauben 11 und 12 auf dem Gestell 2 befestigt. Zuerst wird der Tisch 10 über die Stellschraube 11 in die gewünschte Höhe H bewegt. Dabei ist eine Veränderung des Tisches 10 entsprechend dem Doppelpfeil H nach oben oder unten möglich. Daraufhin wird über die Stellschraube 12 die Neigung des Tisches 10 gemäß Doppelpfeil N eingestellt. Der Tisch 10 ist dabei um einen Drehpunkt im Bereich der Stellschraube 11 drehbar. Die Drehung kann entweder mittels eines nicht dargestellten Gelenkes oder durch eine Verwindung des Tisches 10 erfolgen. Meist ist es ausreichend diese Neigungseinstellung über die Verwindung des Tisches 10 durchzuführen.The following procedure is used to adjust the drafting unit 3 with regard to its height, inclination and position, with respect to the other components of the line 3. The rack 2 is on the floor the hall in which the route is to be set up. A precise height adjustment of the frame 2 is not necessary. The exact setting is carried out via the table 10. The table 10 acts as an adjustment platform for the drafting system 3. The table 10 is fastened to the frame 2 by means of the set screws 11 and 12. First, the table 10 is moved to the desired height H via the adjusting screw 11. A change of the table 10 according to the double arrow H up or down is possible. Thereupon, the inclination of the table 10 is set according to the double arrow N via the adjusting screw 12. The table 10 is rotatable about a pivot point in the area of the adjusting screw 11. The rotation can take place either by means of a joint (not shown) or by twisting the table 10. It is usually sufficient to carry out this inclination adjustment by twisting the table 10.

Nachdem die Höhe und die Neigung des Tisches 10 eingestellt sind, wird die Ausrichtung des Streckwerks 10 in seiner horizontalen Lage eingestellt. Dies erfolgt mittels Bundbolzen 15 und 16. Als vorteilhaft hat sich erwiesen, den Bundbolzen 16 rund und den Bundbolzen 15 exzentrisch auszubilden. Dadurch ist es möglich das Streckwerk 3 bzw. den Lagerbock 4 mittels des exzentrischen Bundbolzens 15 um den runden Bundbolzen 16 zu drehen. Eine genaue Einstellung des Lagerbocks 4 ist damit auf einfache Weise erzielbar.After the height and the inclination of the table 10 are set, the orientation of the drafting system 10 is set in its horizontal position. This is done by means of collar bolts 15 and 16. It has proven to be advantageous to design the collar bolt 16 round and the collar bolt 15 eccentrically. This makes it possible to rotate the drafting system 3 or the bearing block 4 around the round flange bolt 16 by means of the eccentric flange bolt 15. An exact setting of the bearing block 4 can thus be achieved in a simple manner.

Durch diese erfindungsgemäße Einrichtung ist die Einstellung des Streckwerkes einfach und schnell durchführbar. Die Lage des Streckwerkes 3 ist sehr genau justierbar, ohne daß die Befestigungseinrichtungen wieder zu lösen sind, wenn die Lage des Streckwerkes 3 nach einer ersten Einstellung sich als nicht passend erwiesen hat.With this device according to the invention, the setting of the drafting system can be carried out simply and quickly. The position of the drafting system 3 can be adjusted very precisely without the fastening devices are to be solved again if the position of the drafting system 3 has not proven to be suitable after a first adjustment.

In Figur 2 ist eine Zweikopfstrecke 1' in Vorderansicht dargestellt. Ebenso wie bei der Einkopfstrecke 1 besteht die Strecke 1' aus einem Gestell 2, einem Tisch 10, Streckwerken 3 und 3' mit Lagerböcken 4 und 4' und Streckwerkswalzen 5 und 5', sowie nicht dargestellten weiteren Bauteilen. Die Streckwerke 3 und 3' sind nebeneinander auf dem Tisch 10 angeordnet. Die Streckwerkswalzen 5, 5' sind über Wellen 20, 20' und einer Kupplung 21 jeweils miteinander verbunden. Dadurch wird der Antrieb beider Streckwerke 3, 3' über einen einzigen Motor ermöglicht.A front view of a two-head section 1 'is shown in FIG. As with the single-head section 1, the section 1 'consists of a frame 2, a table 10, drafting units 3 and 3' with bearing blocks 4 and 4 'and drafting unit rollers 5 and 5', and further components, not shown. The drafting systems 3 and 3 'are arranged side by side on the table 10. The drafting rollers 5, 5 'are each connected to one another via shafts 20, 20' and a coupling 21. This enables both drafting units 3, 3 'to be driven by a single motor.

Zur Einstellung der Streckwerke 3, 3' wird folgendermaßen vorgegangen. Die Höhenlage des Tisches 10 und damit der Streckwerke 3, 3' wird über innere Stellschrauben 12 eingestellt. Durch eine Verdrehung der Stellschraube 12 wird der Tisch 10 gemäß Doppelpfeil H in seiner Höhe verändert. Dies erfolgt so lange, bis die Streckwerke 3, 3' die gewünschte Höhenlage aufweisen.The procedure for setting the drafting units 3, 3 'is as follows. The height of the table 10 and thus of the drafting units 3, 3 'is set using internal set screws 12. By turning the adjusting screw 12, the height of the table 10 is changed according to the double arrow H. This continues until the drafting units 3, 3 'have the desired altitude.

Nach Erreichung der Höhenlage H wird die Neigung der Streckwerke 3, 3' eingestellt. Über die Stellschrauben 11 und 13, welche zweckmäßigerweise möglichst weit von der Höheneinstellschraube 12 entfernt sind, wird die Neigung der Streckwerke 3 zueinander justiert. Durch Veränderung der Stellschraube 11 wird die Neigung gemäß Doppelpfeil N₁ des Streckwerkes 3 verändert. Die Stellschraube 13 bewirkt eine Neigung gemäß Doppelpfeil N₂ des Streckwerkes 3'. Die Neigungsänderung erfolgt jeweils um einen Drehpunkt im Bereich der Höheneinstellschraube 12. Dazu ist es vorteilhaft, wenn der Tisch 10 entweder im Bereich der Stellschraube 12 drehbar oder zumindest leicht verwindbar ist. Die Einstellung mittels der Stellschrauben 11 und 13 erfolgt so lange, bis die Wellen 20 und 20' vertikal einander genau gegenüberstehen.After reaching the altitude H, the inclination of the drafting units 3, 3 'is set. The inclination of the drafting devices 3 to one another is adjusted via the adjusting screws 11 and 13, which are expediently as far away from the height adjusting screw 12 as possible. By changing the adjusting screw 11, the inclination according to the double arrow N 1 of the drafting device 3 is changed. The set screw 13 causes an inclination according to the double arrow N₂ of the drafting device 3 '. The change in inclination takes place around a pivot point in the area of the height adjustment screw 12. if the table 10 is either rotatable in the area of the set screw 12 or at least slightly twisted. The adjustment by means of the adjusting screws 11 and 13 is carried out until the shafts 20 and 20 'are exactly opposite one another vertically.

Die horizontale Übereinstimmung der Wellen 20 und 20' erfolgt mittels der Bundbolzen 15, 16 und 15', 16'. Durch eine Drehung der exzentrischen Bundbolzen 15, 15' ist die Justierung der Lagerböcke 4, 4' zueinander derart einstellbar, daß die Wellen 20, 20' einander fluchtend gegenüberstehen. Die Drehung der Lagerböcke 4, 4' wird durch eine Drehung der exzentrischen Bundbolzen 15 und 15' um die runden Bundbolzen 16 und 16' bewirkt. Nachdem die Wellen 20 und 20' einander genau fluchtend gegenüberstehen, sind sie über eine Kupplung 21 miteinander verbindbar.The horizontal correspondence of the shafts 20 and 20 'takes place by means of the collar bolts 15, 16 and 15', 16 '. By rotating the eccentric collar bolts 15, 15 ', the adjustment of the bearing blocks 4, 4' to one another can be adjusted such that the shafts 20, 20 'are aligned with one another. The rotation of the bearing blocks 4, 4 'is caused by a rotation of the eccentric collar bolts 15 and 15' around the round collar bolts 16 and 16 '. After the shafts 20 and 20 'face each other exactly in alignment, they can be connected to one another via a coupling 21.

Die lagerichtige Einstellung der Streckwerke 3 und 3' ist besonders bei Zweikopfstrecken wichtig. Für einen gleichmäßigen Verzug der Faserbänder ist es erforderlich, daß die beiden Streckwerke 3 und 3' gleichmäßig angetrieben werden. Dies ist nur möglich, wenn die Wellen 20 und 20' einander fluchtend gegenüberstehen und ohne Versatz oder Neigung in den Wellenachsen verbindbar sind. Durch die erfindungsgemäße Vorrichtung und das erfindungsgemäße Einstellverfahren ist die genaue und einfache Einstellung der beiden Streckwerke 3 und 3' auf einfache Weise möglich. Eine gleichmäßige und gute Faserbandqualität ist somit bei einer Strecke 1' mit dem erfindungsgemäßen Verfahren und der Vorrichtung erzielbar.The correct setting of the drafting units 3 and 3 'is particularly important for two-head draw frames. For a uniform warping of the slivers, it is necessary that the two drafting units 3 and 3 'are driven uniformly. This is only possible if the shafts 20 and 20 'are aligned with one another and can be connected in the shaft axes without offset or inclination. The device according to the invention and the setting method according to the invention make it possible to set the two drafting units 3 and 3 'in a simple and precise manner. A uniform and good sliver quality can thus be achieved on a section 1 'with the method and the device according to the invention.

In Figur 3 ist zur Verdeutlichung der Erfindung noch eine Draufsicht auf die Zweikopfstrecke 1' dargestellt. Daraus ist ersichtlich, daß der Tisch 10 die beiden Streckwerke 3 und 3' trägt. In den Lagerböcken 4 und 4' sind jeweils mehrere Streckwerkswalzen 5 und 5' angeordnet. Jede dieser Streckwerkswalzen 5 und 5' ist über Wellen 20 und 20' und einer Kupplung 21 mit der jeweils korrespondierenden Streckwerkswalze verbunden.In Figure 3, a plan view of the two-head section 1 'is shown to illustrate the invention. From this it can be seen that the table 10 carries the two drafting systems 3 and 3 '. In the bearing blocks 4 and 4 'each have a plurality of drafting rollers 5 and 5'. Each of these drafting rollers 5 and 5 'is connected to the corresponding drafting roller via shafts 20 and 20' and a coupling 21.

Zur Stabilität der Einstellung des Tisches 10 ist es vorteilhaft, wenn jeweils zwei der Stellschrauben 11, 12 und 13 verwendet werden. Dadurch werden die Anforderungen an eine lagegenaue Montage des Gestells 2 minimiert. Die Einstellmöglichkeiten des Tisches 10 werden dadurch nochmals vergrößert, da eine Neigungsjustierung orthogonal zu den Neigungen N₁ und N₂ möglich sind.For the stability of the setting of the table 10, it is advantageous if two of the adjusting screws 11, 12 and 13 are used in each case. This minimizes the requirements for an accurate mounting of the frame 2. The setting options of the table 10 are thereby increased again, since an inclination adjustment orthogonal to the inclinations N 1 and N 2 is possible.

Aus der Darstellung der Figur 3 ist weiterhin ersichtlich, daß über die exzentrischen Bundbolzen 15, 15' und die runden Bundbolzen 16, 16', welche als Drehpunkt dienen, eine Drehung der Lagerböcke 4, 4' gemäß Doppelpfeil D, D' erfolgt. Dadurch ist eine horizontale Einstellung der Streckwerke 3, 3' zueinander und damit auch eine fluchtende Übereinstimmung der Wellen 20, 20' zueinander möglich.From the illustration in FIG. 3 it can also be seen that the bearing blocks 4, 4 'are rotated according to the double arrow D, D' via the eccentric flange bolts 15, 15 'and the round flange bolts 16, 16', which serve as the fulcrum. As a result, the drafting units 3, 3 'can be adjusted horizontally to one another and thus the shafts 20, 20' can be aligned with one another.

Die Erfindung ist nicht auf die dargestellen Ausführungsbeispiele beschränkt.The invention is not restricted to the exemplary embodiments shown.
