Description

Die Erfindung betrifft eine Selektionseinrichtung für Textilmaschinen, wie Jacquard-, Raschel- oder Kartenschlagmaschinen, zum mustergemäßen Betätigen von Einlese- oder sonstigen Steuerelementen, z.B. zum Abdrücken von Steuernadeln oder Einleseschiebern bzw. von Platinen oder dgl., bei welcher eine Anzahl von durch Aufprägen eines elektrischen oder magnetischen Feldes sich biegenden, etwa stab- oder streifenförmigen Biegeschwingern, die in einem Rahmen oder Gestell parallel zueinander angeordnet und jeweils mit einem zwischen zwei Positionen hin- und herbewegbaren Sperrelement verbunden sind, wobei bei Relativbewegung zwischen der Vorrichtung und den Einleseelementen je nach Ausbiegung der Biegeschwinger das einzelne Sperrelement gegen das ihm zugeordnete Einleseelement anschlägt oder nicht anschlägt.The invention relates to a selection device for textile machines, such as jacquard, rustling or card punching machines, for the actuation of reading or other control elements, e.g. for pressing control needles or read-in slides or of circuit boards or the like, in which a number of bending rods, for example rod-shaped or strip-shaped, are bent by the application of an electrical or magnetic field, which are arranged parallel to one another in a frame or frame and each with a between Two positions of the locking element which can be moved to and fro are connected, with the individual locking element striking or not striking against the reading element assigned to it, depending on the deflection of the bending oscillators, in the case of a relative movement between the device and the reading elements.

Textilmaschinen, welche Selektionseinrichtongen aufweisen, die mit solchen Biegeschwingern arbeiten, sind bereits bekannt (z.B. DE-PS 22 30 487, DE-PS 21 30 502 und DE-AS 25 09 217). Hierbei sind die Biegeschwinger mit ihrem einen Ende in einem Rahmen fest eingespannt, während ihr freies Ende hin und her schwingt und dabei einen am Rahmen sich abstützenden Sperrschieber oder dgl. zwischen zwei Stellungen hin und her bewegt. Die jeweilige Stellung dieses Steuerschiebers wird durch Abdrücknadeln, die auf Platinen oder dgl. einwirken, abgetastet. Die einseitig eingespannten Biegeschwinger können mit ihrem beweglichen freien Ende nur sehr geringe Kräfte übertragen, da sie infolge ihres spröden Werkstoffes schon bei geringen Spannungen zum Bruch neigen.Textile machines which have selection devices which work with such bending oscillators are already known (e.g. DE-PS 22 30 487, DE-PS 21 30 502 and DE-AS 25 09 217). Here, the flexural vibrators are firmly clamped at one end in a frame, while their free end swings back and forth and thereby moves a locking slide or the like, which is supported on the frame, between two positions. The respective position of this control slide is scanned by push-off needles which act on circuit boards or the like. The flexible oscillators clamped on one side can only transmit very small forces with their movable free end, since their brittle material tends to break them even at low stresses.

. Aufgabe der Erfindung ist es daher, eine einfache Ausbildung der Selektionseinrichtung zu schaffen, die stabiler, kompakter und weniger platzbedürftig ist.. The object of the invention is therefore to provide a simple design of the selection device which is more stable, more compact and takes up less space.

Gemäß der Erfindung besteht die Lösung dieser Aufgabe darin, daß die Biegeschwinger mit ihren beiden Enden an zwei gegenüberliegenden Stellen gelagert sind und das am Gehäuse sich abstützende Sperrelement im Bereich des zwischen den beiden Lagerstellen befindlichen Schwingungsbauches befestigt ist. Hierdurch erhält man eine stabile und kompakte Anordnung. Durch das sich am Gehäuse abstützende Sperrelement werden die von den Abdrücknadeln oder sonstigen Einleseelementen ausgeübten Kräfte aufgenommen.According to the invention, the solution to this problem is that the flexural vibrators are mounted with their two ends at two opposite points and the locking element supported on the housing is fastened in the region of the antinode located between the two bearing points. This gives a stable and compact arrangement. The locking element supported on the housing absorbs the forces exerted by the push-off needles or other reading elements.

Eine besonders platzsparende Ausführung wird dadurch erreicht, daß die einzelnen Biegeschwinger in paralleler Lage mit ihrem einen Ende neben dem Ende des ihnen jeweils zugeordneten, ebenfalls stab- oder streifenförmig ausgebildeten Einleseelemente angeordnet sind. Bei einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, daß ein jeweils zwischen zwei Biegeschwingern angeordneter Stützanschlag für das Sperrelement zugleich als Begrenzungsanschlag für den Bewegungshub der Biegeschwinger ausgebildet ist. Ebenfalls erweist es sich als vorteilhaft, daß die Biegeschwinger mit ihren Enden in den Lagerstellen lose gelagert sind. Dies kann beispielsweise dadurch geschehen, daß die Schwinger mit ihren Enden in konischen Schlitzen gelagert sind oder daß die Enden in elastisch nachgiebigen Lagerelementen gehalten sind. Unnötige Biegespannungen werden hierdurch vermieden.A particularly space-saving design is achieved in that the individual flexural vibrators are arranged in a parallel position with their one end next to the end of the reading elements which are also assigned to them and are also rod-shaped or strip-shaped. In an advantageous development of the invention, it is provided that a support stop for the locking element, which is arranged between two bending oscillators, is at the same time designed as a limit stop for the movement stroke of the bending oscillators. It also proves to be advantageous that the flexible oscillators are loosely supported with their ends in the bearing points. This can happen, for example, in that the ends of the oscillators are mounted in conical slots or in that the ends are held in elastically flexible bearing elements. This avoids unnecessary bending stresses.

In dem Beispiel gemäß Fig. 1 und 2 bzw. Fig. 3 und 4 aus Kunststoff bestehenden Behäuse 1 sind in horizontaler Richtung Führungsbohrungen 10a angebracht (Fig. 1 und 3), durch welche die Enden 33 der Abdrückelemente 9 geführt sind. Das Kunststoffgehäuse ist als Grundplatte 1b (Fig. 2 und 4) ausgeführt, auf der hinten und vorne bzw. zu beiden Seiten Erhöhungen gebildet sind, die zur Führung der Abdrückelemente 9 und zur Lagerung von streifenförmigen Biegeschwingern 2 dienen. Diese Erhöhungen können zum Beispiel aus einem Stück mit der Grundplatte 1b bestehen.In the example according to FIGS. 1 and 2 or FIGS. 3 and 4 housing 1 made of plastic, guide bores 10a are made in the horizontal direction (FIGS. 1 and 3) through which the ends 33 of the push-off elements 9 are guided. The plastic housing is designed as a base plate 1b (FIGS. 2 and 4) on which ridges are formed at the rear and front or on both sides, which are used to guide the push-off elements 9 and to support strip-shaped bending oscillators 2. These elevations can, for example, consist of one piece with the base plate 1b.

In den Erhöhungen 3 hinten und vorne an der Grundplatte 1 sind konische Schlitze 3a angebracht (s. Fig. 1 und 2), in denen die linke Seite des Biegeschwingers 2 gelagert ist. In den Erhöhungen 10 hinten und vorne auf der Grundplatte 1 sind auf der rechten Seite ebenfalls konische Schlitze 3a angebracht, die zur rechten Lagerung des Biegeschwingers dienen. In diesen beiden Schlitzen ist der Biegeschwinger 2 links und rechts gelagert.Conical slots 3a (see FIGS. 1 and 2) in which the left side of the bending oscillator 2 is mounted are provided in the elevations 3 at the rear and front of the base plate 1. In the elevations 10 at the rear and front on the base plate 1, conical slots 3a are also provided on the right-hand side, which serve for the right-hand mounting of the bending vibrator. The bending vibrator 2 is mounted on the left and right in these two slots.

In der Mitte der Grundplatte 1 b sind hinten und vorne die Erhöhungen 8 gebildet, die als Anschlag bzw. als Amboss für das Sperrelement 5 dienen, das auf dem Biegeschwinger über die elastische Klebeverbindung 6 verbunden ist. Auf der Anschlagfläche 8a wird die Axialkraft des Abdrückelementes aufgenommen. An dem linken Ende des Biegeschwingers ist ein Stellring 4 angebracht, der ein horizontales Verschieben des Biegeschwingers nach rechts verhindert. Zur besseren Funktion und hoher Betriebssicherheit bzw. zum Eliminieren von Wärme-Ausdehnungen ist der Biegeschwinger zwischen Stellring 4 und Sperrelement 5 mit dem Spiel Z eingebaut.In the middle of the base plate 1 b, the ridges 8 are formed at the back and front, which serve as a stop or as an anvil for the locking element 5, which is connected to the flexural oscillator via the elastic adhesive connection 6. On the stop surface 8a absorbs the axial force of the push-off element. At the left end of the bending vibrator there is an adjusting ring 4 which prevents the bending vibrator from moving horizontally to the right. For better function and high operational safety or to eliminate thermal expansion, the bending oscillator is installed between the collar 4 and the blocking element 5 with the play Z.

An jedem Biegeschwinger sind Sperrelemente 5 über eine elastische Klebeverbindung 6 angebracht, die aus Kunststoff sind, z.B. aus Polyamid, und diese haben eine Einlage 7 aus gehärtetem Stahl. Auf sie treffen die Abdrückelemente 9 während des Betriebes, z.B. in der Sperrstellung 2b (unten, Fig. 1 und Fig. 3).Locking elements 5, which are made of plastic, e.g. made of polyamide, and these have an insert 7 made of hardened steel. The push-off elements 9 meet them during operation, e.g. in the locked position 2b (below, Fig. 1 and Fig. 3).

Der Einbau der beidseitig gelagerten Biegeschwinger 2 in das Kunststoffgehäuse 1 ist sehr einfach, diese werden komplett mit dem Sperrstück 5 und dem Begrenzungs-Stellring 4 hinten und vorne des Gehäuses 1 in die Schlitze 3a der Erhöhungen 3 und 10 geschoben. Als seitliche Begrenzung hinten und vorne dienen die Abdeckplatten 1a.The installation of the flexural vibrators 2 on both sides into the plastic housing 1 is very simple, they are pushed completely into the slots 3a of the elevations 3 and 10 with the locking piece 5 and the limiting adjusting ring 4 at the rear and front of the housing 1. The cover plates 1a serve as a lateral limitation at the rear and front.

Die Sperrstücke 5 sind seitlich an den Flächen 11 und 11a begrenzt bzw. geführt, so daß keine Verdrehung des Sperrstückes 5 bzw. des Biegeschwingers 2 auftreten kann.The locking pieces 5 are laterally delimited or guided on the surfaces 11 and 11a, so that no twisting of the locking piece 5 or the bending vibrator 2 can occur.

Während des Betriebes erhalten die Biegeschwinger 2 über elektrische Zuführungsleitungen 12 entsprechend einem Textilmusterprogramm für die Kartenschlagmaschine oder einem Textilmusterprogramm für die Raschelmaschine Spannung, so daß sie beispielsweise in die eine Richtung (Stellung 2a, oben) oder in die andere Richtung (Stellung 2b, unten) ausgelenkt werden. Die spannungslose Mittelstellung ist mit 2 bezeichnet. Entsprechend der Bewegung der Biegeschwinger gehen die Sperrelemente 5 ebenfalls in die Sperrstellung 2b oder wirkungslose Stellung 2a, oder sie verbleiben in der Mittelstellung.During operation, the bending vibrators 2 are supplied with voltage via electrical supply lines 12 in accordance with a textile pattern program for the card punching machine or a textile pattern program for the Raschel machine, so that they move in one direction (position 2a, up) or in the other direction (position 2b, down), for example. be deflected. The de-energized middle position is designated by 2. According to the movement of the bending vibrators, the blocking elements 5 also go into the blocking position 2b or inactive position 2a, or they remain in the central position.

Beim Einlesevorgang erfolgt eine Bewegung der Abdrückelemente und Biegeschwinger relativ zueinander in Richtung ihrer Längsachse. Je nach Stellung der Biegeschwinger gelangen z.B. die Abdrückelemente 9 in die Stellung 9a, d.h., eine nach links verlaufende Abtastbewegung der Abdrückelemente 9 wird gesperrt. Andere Abdrückelemente 9 gelangen durch die nach links verlaufende Abtastbewegung in die Stellung 9b.During the reading-in process, the push-off elements and bending vibrators move relative to one another in the direction of their longitudinal axis. Depending on the position of the bending vibrators, e.g. the push-off elements 9 into position 9a, i.e. a left scanning movement of the push-off elements 9 is blocked. Other push-off elements 9 reach position 9b by the scanning movement running to the left.

Die Länge des Sperrelementes 5 ist mindestens so lang wie der Hub des Abdrückelementes sein muß. Der Hub jedes Sperrelementes 5 bzw. jedes Biegeschwingers 2 wird durch die Anschläge 8b unten und 8c oben begrenzt.The length of the locking element 5 is at least as long as the stroke of the push-off element must be. The stroke of each locking element 5 or each bending vibrator 2 is limited by the stops 8b below and 8c above.

Bei der erfindungsgemäß abgewandelten Ausführungsform eines beidseitig eingespannten Biegeschwingers nach Fig. 3 und 4 dieser statt in Schlitzen in den Enden links und rechts ungefähr in den Schwingungsknoten in einem Gummi-oder Kunststoff-Lager 4a gehaltert. Als Lagerungs-Medium kann zum Beispiel Schaumgummi 4a dienen, das in der Aussparung 3b gehaltert ist und da dieses sehr elastisch ist, kommt es auf eine genaue Positionierung der Lagerung nicht an.3 and 4, the latter is held in a rubber or plastic bearing 4a instead of in slots in the ends on the left and right approximately in the vibration nodes. Foam rubber 4a, which is held in the recess 3b and can be used as the storage medium, for example, and since this is very elastic, the precise positioning of the bearing is not important.

Bei der in der oberen Hälfte der Fig. 5 dargestellten Einlese- und Selektionsvorrichtung für Kartenschlagmaschinen sind in einem Gestell Fallplatinen 13 angeordnet, die je nach Stellung der Aussparung 14 bei dem Abdrückelement 9 durch eine Bewegung nach unten über entsprechende Zwischenglieder, wie Fallnadeln, Stoßnadeln und Übertragungsstößel, die Stanzstempel beeinflussen. Die Abdrückelemente 9 sind als Einleseelemente ausgebildet, bei dem hier dargestellten Beispiel als schmale, längliche, in horizontaler Richtung bewegbare Schieber. Die Einleseelemente sind in Form von 84, jeweils in einer Ebene übereinanderliegende Gruppen von 16 Elementen angeordnet. Die Abdrückelemente 9 werden durch einen gemäß Pfeil X hin-und herbewegbaren Druckrechen 15 angetrieben. Auf den in Fig. linken Enden 16 der Abdrückelemente, die in dem Abdrückrechen 15 geführt sind, sind Federn 17 eingesetzt, über diese die horizontale Bewegung der Einleseelemente 9 erfolgt.In the upper half of FIG. 5, the reading and selection device for card-making machines, drop plates 13 are arranged in a frame, which, depending on the position of the recess 14 in the push-off element 9, are moved downward via corresponding intermediate links, such as drop pins, push pins and Transfer rams that affect stamps. The push-off elements 9 are designed as reading elements, in the example shown here as narrow, elongated sliders that can be moved in the horizontal direction. The reading elements are arranged in the form of 84 groups of 16 elements, one above the other in one plane. The push-off elements 9 are driven by a pressure rake 15 which can be moved back and forth according to arrow X. Springs 17 are inserted on the left ends 16 of the pushing elements, which are guided in the pushing rake 15, via which the horizontal movement of the reading elements 9 takes place.

In den Zwischenräumen zwischen den einzelnen, jeweils in einer Ebene liegenden 16-er-Gruppen der Einleseelemente 9, befinden sich jeweils 16 der flachen Fallplatinen 13, die in einem gemäß Pfeil Y auf- und abbewegbaren Rost 18 hängen.In the spaces between the individual groups of 16 of reading elements 9, each lying in one plane, there are 16 of the flat falling plates 13, which hang in a grate 18 that can be moved up and down according to arrow Y.

Diese Fallplatinen 13 besitzen seitlich nach außen ragende Zapfen 19, mit denen sie auf den Einleseschiebern 9 aufliegen können. Hierbei sind die Zapfen 19 der ersten 8 Fallplatinen nach der einen und die der 8 anderen Fallplatinen nach der anderen Seite gerichtet.These falling boards 13 have laterally outwardly projecting pins 19 with which they can rest on the read-in slides 9. Here, the pins 19 of the first 8 fall boards are directed to one side and those of the 8 other fall boards to the other side.

Zu Beginn der Einlesebewegung ist der Schieber 18 mit den daran über die Zapfen 20 hängenden Fallplatinen 13 nach oben bewegt. Alsdann wird der Druckrechen 15 durch den nicht dargestellten Maschinenantrieb nach rechts bewegt und die Einleseelemente können sich über die Feder 17 je nach Lage des durch das im Gehäuse 21 gelagerten Steuerorgan 2 betätigte Sperrelement 5 horizontal nach rechts in die Selektionsposition verschieben oder nicht verschieben. D.h., hat sich das Sperrelement 5 entsprechend der Information der Auswahlelektronik nach unten bewegt, so wird die Abtastbewegung des Einleseelementes 9 gesperrt und es erfolgt keine Horizontalbewegung, lediglich die Feder 17 wird zusammengedrückt. Ist das Sperrelement 5 in der Oberstellung, so kann das Einleseelement die Horizontalbewegung über die Feder 17 ausführen.At the beginning of Einlesebewegung the slider 18 moves with it about the pin 2 0 hanging case boards 13 upward. Then, the pressure rake 15 is moved to the right by the machine drive, not shown, and the reading elements can be moved horizontally to the right into the selection position or not via the spring 17, depending on the position of the locking element 5 actuated by the control element 2 mounted in the housing 21. That is, if the blocking element 5 has moved downwards in accordance with the information from the selection electronics, the scanning movement of the reading element 9 is blocked and there is no horizontal movement, only the spring 17 is compressed. If the blocking element 5 is in the upper position, the reading element can carry out the horizontal movement via the spring 17.

Bei dem sich dann anschließenden Absenken des Rostes 18 stützen sich die Fallplatinen 13 mit ihren Zapfen 19 je nach der Stellung des ihnen zugeordneten Einleseelementes 9 entweder auf dessen Oberkante ab oder sie fallen, wenn das ihnen zugeordnete Einleseelement nicht gesperrt wurde, in die hierfür vorgesehene Ausnehmung 14 ihres Einleseelements 9, wodurch sich in dem darunter befindlichen Stoßnadelwerk 22 der Kartenschlagmaschine die entsprechenden Stoßnadein absenken und die entsprechenden Stanzstempel 23 über den Druckrechen 24 betätigt werden.When the grate 18 is then lowered, the falling plates 13 are supported with their pins 19, depending on the position of the reading element 9 assigned to them, either from its upper edge or if the reading element assigned to them has not been locked, they fall into the recess provided for this purpose 14 of its reading element 9, which ent ent in the push needle 22 of the card striking machine located below lower speaking push pin and the corresponding punches 23 are actuated via the pressure rake 24.

Bei der in Fig. 6 dargestellten Einlese- und Selektionsvorrichtung einer Raschelmaschine sind Platinen 25 in einem Gestell 29 angeordnet, die mit den Hubmessern 26 gekoppelt werden können. Von den Platinen 25 aus werden über Steuerzüge 28 die Verdrängerstifte 27 in die mustergemäße Auswahl-Position nach oben bewegt.In the reading and selection device of a Raschel machine shown in FIG. 6, boards 25 are arranged in a frame 29 which can be coupled to the lifting knives 26. From the boards 25, the displacer pins 27 are moved upwards into the pattern-like selection position via control cables 28.

Die Platinen 25 werden von horizontalen Abdrückelementen 9 abgedrückt, d.h. gemäß Pfeil X' hin und her bewegt, so daß ihr Haken 34 z.B. außerhalb oder innerhalb des Bereiches der Hubmesser 26 stehen (Aus- und Einkuppeln). Die Abdrückelemente 9, die als schmale längliche Einleseschieber ausgebildet sind, werden durch einen gemäß Pfeil X-hin und her bewegten Druckrechen 30 angetrieben. An den in Fig. 6 rechten Enden 31 der Abdrückelemente, die in dem Abdrückrechen 30 geführt sind, sind Federn 32 eingesetzt, über die die horizontale Bewegung der Einleseschieber 9 erfolgt. Die Selektionseinrichtung 21 befindet sich am linken Ende 33 der Einleseschieber.The boards 25 are pressed by horizontal push-off elements 9, i.e. moved back and forth according to arrow X 'so that its hook 34 e.g. stand outside or within the range of the lifting knives 26 (disengaging and engaging). The push-off elements 9, which are designed as narrow, elongated read-in slides, are driven by a pressure rake 30 which is moved back and forth according to arrow X. At the right ends 31 in FIG. 6 of the push-off elements, which are guided in the push-off rake 30, springs 32 are inserted, via which the horizontal movement of the read-in slides 9 takes place. The selection device 21 is located at the left end 33 of the reading slide.

Zur elektrischen Steuerung von Jacquardmaschinen werden beispielsweise gemäß Fig. 7 bis zu 1344 Biegeschwinger 2 der geschilderten Art reihen- und blockweise in einem Rahmen 21 zusammengefaßt und anstelle des bekannten Vornadelwerkes einer Jacquardmaschine vorgeschaltet. Von einem beliebigen, nicht dargestellten Informationsgeber wie z.B. Lochkarte, Magnetband oder Disk erhalten die piezoelektrischen Biegeschwinger 2 Steuerimpulse. Diese Impulse bewirken, daß die Sperrelemente 5 bzw. die Biegeschwinger 2 in eine nach oben oder nach unten gerichtete definierte Stellung kommen (Fig. 1 und 3), also zwischen den Erhöhungen 8 an einem der beiden Anschlagsflächen 8b oder 8c zur Anlage kommen und dort unter der Wirkung der elektrischen Kraft entsprechend zeitlich verbleiben. Durch die folgende horizontale Bewegung des Rahmens 21 mit allen in ihm zusammengefaßten Biegeschwinger gegen die Jacquardmaschine hin treffen die nach unten gerichteten Sperrelemente 5 gegen die Abdrückelemente 9, die in dem dargestellten Beispiel als längliche, in horizontaler Richtung bewegbare Steuernadeln ausgebildet sind. Diese Steuernadeln 9 sind in der Führungsplatte 35 geführt. Die Steuernadeln 9 entkuppeln die Platinen 37 von den Hubmessern 36 der Jacquardmaschine. Beim anschließenden Hochgang dieser Hubmesser 36 werden diese von ihnen abgekuppelten Platinen 37 und die von ihnen betätigten nicht dargestellten Kettfäden in der Webmaschine in Tiefstellung verbleiben. Die von den nach oben gerichteten Sperrelemente 5 an Biegeschwingern 2 dagegen nicht beeinflußten Abdrückelemente bzw. Steuernadeln 9 belassen die Platinen 37 in ihrer Zuordnung zu den Hubmessern 36 und werden mit den von ihnen betätigten Kettfäden von diesen Hubmessern 36 in die Hochstellung verbracht und auf diese Weise das mustergemäß vorgeschriebene Webfach gebildet.For the electrical control of jacquard machines, for example, as shown in FIG. 7, up to 1344 flexural vibrators 2 of the type described are combined in rows and blocks in a frame 21 and connected upstream of a jacquard machine instead of the known pre-needle mechanism. From any information provider, not shown, such as Punch cards, magnetic tapes or disks receive 2 control impulses for the piezoelectric bending transducers. These impulses cause the blocking elements 5 and the bending vibrators 2 to come into a defined position directed upwards or downwards (FIGS. 1 and 3), that is to say they come to rest between the elevations 8 on one of the two stop surfaces 8b or 8c and there remain correspondingly in time under the effect of the electrical force. As a result of the subsequent horizontal movement of the frame 21 with all the flexural vibrators combined in it against the jacquard machine, the blocking elements 5 directed downward hit the push-off elements 9, which in the example shown are designed as elongated control needles which can be moved in the horizontal direction. These control needles 9 are guided in the guide plate 35. The control needles 9 decouple the sinkers 37 from the lifting knives 36 of the jacquard machine. When these lifting knives 36 then ramp up, these sinkers 37, which they have uncoupled, and the warp threads, not shown, which they actuate, remain in the lower position in the weaving machine. The push-off elements or control needles 9, on the other hand, which are not influenced by the upward blocking elements 5 on bending oscillators 2, leave the sinkers 37 in their association with the lifting knives 36 and are brought into the high position with the warp threads actuated by them by these lifting knives 36 and in this way the weaving shed prescribed according to the pattern.

Zur elektrischen Ansteuerung einer Schaftmaschine nach Figur 8 wirken die Sperrelemente 5 der Biegeschwinger 2 in äquivalenter Weise auf die Abdrückelemente 9, welche bei Schaftmaschinen bekannterweise als Steuernadeln ausgebildet sind, die ihrerseits die Hubstifte 39 in oder außer Bereich der Hilfsmesser 40 bringen. Auf diese Weise von den durch die Sperrelemente 5 betätigten Steuernadeln bzw. Abdrückelemente 9, die in der Führung 38 geführt sind, außer Bereich der Hilfsmesser 40 gebrachten Hubstifte 39 verbleiben in Tiefstellung. Mit ihnen bleiben die Platinen 41 in Tiefstellung den Hauptmessern 42 oder 43 der Schaftmaschine zugeordnet, die bei ihrem Vorgehen über sie, Balancehebel 44 und Schafthebel 45 die Webschäfte in Hochstellung verbringen.For the electrical control of a dobby according to FIG. 8, the blocking elements 5 of the flexural vibrators 2 act in an equivalent manner on the push-off elements 9, which are known in the form of dobby machines as control needles, which in turn bring the lifting pins 39 into or out of the area of the auxiliary knives 40. In this way, lifting pins 39 brought out of the area of the auxiliary knives 40 by the control needles or push-off elements 9 which are actuated by the locking elements 5 and which are guided in the guide 38 remain in the low position. With them, the sinkers 41 remain in the lower position associated with the main knives 42 or 43 of the dobby, which in their action on them, balance lever 44 and shaft lever 45 spend the heald frames in the high position.

Von den Sperrelementen 5 wegen ihrer anders gerichteten Stellung nicht betätigte Steuernadeln 9, die in der Platte 38 geführt sind dagegen belassen die Hubstifte 39 in ihrer Zuordnung zu den Hilfsmessern 40, die dadurch bei ihrem Hochgang über die Hubstifte 39 die Platinen 41 angeben und dadurch von den Hauptmessern 42 oder 43 abkuppeln. Die diesen Platinen zugeordneten Webschäfte werden daher in TiefsteIlung verbleiben, wodurch ebenfalls das mustergemäß vorgeschriebene Webfach gebildet wird.Control pins 9, which are not actuated by the locking elements 5 because of their differently directed position, which are guided in the plate 38, on the other hand, leave the lifting pins 39 in their assignment to the auxiliary knives 40, which thereby indicate the boards 41 during their ascent via the lifting pins 39 and thereby uncouple the main blades 42 or 43. The heald frames assigned to these sinkers will therefore remain at their lowest position, which also forms the shed compartment prescribed according to the pattern.
