Definitions
- the invention relates to a shed forming device for textile technology with monofilament control (jacquard technique), which works with one spring at the top and bottom of the heddle in so-called Offenfacharbeit Anlagen at 180 ° rotation of the shedding device per weft insertion, this operation by two closely spaced different functional and switching processes is only possible.
- the upper and lower Hubfederrahmen with the springs moves in Webschusseintragstakt from top to bottom and from bottom to top, etc.
- a stationary locking element can then lock the healds in high and low depth in the open shed example pattern and unlock (couple and decouple).
- the so-called Webharnisch is waived.
- weaving machines with “jacquard machines” and “weaving arms” ( FIG. 1 ) with weaving machine (1), jacquard machine (2) and weaving brace (3), and “harnessless shedding devices” ( FIG. 2 ) without weaving, with counter-rotating movable lifting elements (4,5) and stationary locking elements (6) known, the healds (7) with their thread eyes (8) by the elements (4,5,6) locked and in the respective subject position to be moved.
- the locking devices are components of the elements (4,5,6) and in the guide openings (9) integrated.
- the shedding device DE 19934447 A1 to FIG. 2 has the disadvantage that three actuators are required for each heald; two actuators as components of the two movable lifting elements 4,5, and an actuator as part of the stationary locking element 6.
- This illustration corresponds to the FIG. 5 from the patent DE 199 34 447 A1 , in which the two lifting elements with 25 and 26, and the fixed locking member is denoted by 8.
- the system (it is a so-called oscillating system) is set in permanent oscillation, so that the healse joins in this oscillation and makes the way from low to high and vice versa. If the heddle should remain in the deep or high compartment, it should be held by a holding device accordingly.
- This mode of operation has the serious disadvantage that the healds always have to make the complete path deep-high-low, or high-low-high by means of the oscillating device for each web shot, since otherwise the pattern and binding-appropriate position of the healds can not be achieved , So there is always a 360 degree swing required per hoop entry.
- the publications DE 101 44 085 A1 and DE 101 46 302 A1 are concerned with delayed locking of the heddles, and in no way affect the novel technique presented here.
- the patent CH 562 341 from the year 1972 deals with the control of the movements of yarn guide organs in textile machines which has no fiction relevant commonalities with the technology presented below.
- the publication DE 27 46 094 from 1977 deals with a sumanetechnik, which likewise has no similarities relevant to the invention.
- Object of the present invention was to provide for the so-called "jacquard" with monofilament control a shedding device that works in Offenfacharbeit Anlagen and make the lifting elements (Hubfederrahmen) for each Webschusseintrag only a stroke of 180 °, and which, of course, a much higher Webschustragtragsiere / Time unit can be achieved; as in a mode of operation with 360 ° stroke of the lifting elements per weft insertion.
- the shedding devices with operation according to the so-called open shed principle and 180 ° rotation / Webschusseintrag the shedding device with two counter-rotating lifting elements for the high and low position, only one lifting element for the high and low position is required according to the invention. Using the different functional and Switching operations can nevertheless be carried out according to the so-called open compartment principle and 180 ° rotation of the shedding device per weft insertion.
- the present invention should work without Webharnisch work as simple and safe, and cost to get by with only one locking device per heald.
- This object is achieved by a shedding device which operates according to the invention, each with a spring at the top and bottom of the heald.
- the springs are attached to a lower and upper Hubfederrahmen.
- the healds are coupled by a stationary locking element pattern in the high or low compartment.
- the upper and lower Hubfederrahmen with the springs moves the same direction in Webschusseintragstakt from top to bottom and from bottom to top, etc., so that the locking devices (as described above) can match the healds in the high and low depth pattern.
- FIG. 1 shows a weaving machine as described in the prior art, with loom (1), jacquard machine (2), and weaving braid (3).
- FIG. 2 shows a shedding device as described in the prior art, with two movable lifting elements (4,5), with a stationary locking element (6) with healds (7) and thread eyes (8), and with guide openings (9) for the integration of locking devices depending heddle.
- This representation corresponds to the FIG. 5 from the patent DE 199 34 447 A1 , In this FIG. 5 the two lifting elements are denoted by 25 and 26, and the stationary locking element 8.
- FIG. 3 shows the essential components according to the invention of the shedding device with the following designations: warp beam 10, cloth beam 11, string tree 12, breast tree 13, stationary locking element 14, with controllable locking points (27,28,29,30) for coupling the healds, (lower movable Hubfederrahmen 17th , for securing the springs 19, 20,) (upper movable lifting spring frame 18, for securing the springs 21, 22,) left heald 25, with thread eye 23, and with warp thread 15, right heald 26, with thread eye 24, and with warp thread 16 , Webware 31, shed 32, for entering the fabric shots., Upper adjustable stop bar 41, lower adjustable stop bar 42, stop point on the heald 43rd
- the movable Hubfederrahmen 17,18 are in the lower position.
- the heald 25, is decoupled, and has therefore moved with the two Hubfederrahmen 17,18, and the springs 19,21 attached thereto, down in the Tieffach.
- the springs are in a certain bias so that the heald safely and quietly guided and can be moved, and thus the required shed opening can be achieved stable and safe and reproducible.
- the heald 26 was, before lowering the Hubfederrahmen 17,18, coupled to the coupling point 29 to the stationary locking element 14. The heald 26, has therefore remained in the high box.
- FIG. 4 and FIG. 5 shows the movement sequence of the shedding device according to the invention.
- the pattern-oriented reading and selection process is to be divided into two closely spaced functional sequences. These different functional sequences are used for the first web shot under (A.1 and A.2), for the second web shot under (B.1 and B.2) for the third web shot under (C.1 and C.2) and for the fourth web shot under (D.1 and D.2) shown, and explained.
- the position A.1 corresponds to the illustration in FIG. 3 ,
- the heald 26, is decoupled, and has therefore moved with the two Hubfederrahmen 17,18, and the springs 20,22 attached thereto, down in the Tieffach, (see C.1). Since at the fourth web shot (see D.1) the heald 25 should remain in the high bay, the coupling 27 remains (see C.2). Since in the fourth web shot the heald 26 is to remain in the lower shed, the coupling point 30 is coupled (see C.2). Now move the Hubfederrahmen 17,18, upwards, (see D.1). The heald 25, has remained in the high bay due to the coupling 27. Due to the upward movement of Hubfederrahmen 17,18, the springs 19,21, brought into their neutral or normal length. The heald 26, has remained in the Tieffach due to the coupling 30. The spring 22 is stretched and the spring 20 is compressed (see D.1).
- FIG. 6 shows a further inventive embodiment of the shedding device.
- the in the Figures (3 . 4 . 5 ) described mode of operation with a bottom and a top arranged movable Hubfederrahmen 17,18, may alternatively work so that only one of the two spring frame is movable, and as Hubfederrahmen the required lifting movement for moving the healds of low-high-low-high, etc . power.
- the opposite spring frame can then be installed stationary.
- the FIG. 6 shows this the stationary spring frame 33, the movable Hubfederrahmen 18, the healds 25,26, with the thread eyes 23,24, also the springs 19,20,21,22, and the stationary locking member 14, with for coupling the healds.
- the stationary spring frame 33, the movable Hubfederrahmen 18, the healds 25,26, with the thread eyes 23,24 also the springs 19,20,21,22, and the stationary locking member 14, with for coupling the healds.
- FIG. 7 shows additional sliding elements, which have the task to allow a smooth movement of the movable Hubfederrahmen.
- FIG. 7 shows this three heald positions A, B, C., the stationary locking element 14, the movable Hubfederrahmen 34, the stationary spring frame 35, the lower spring 36, the upper spring 37, the heald 38, with thread eye 23, the sliding element with outer part 39 and with inner part 40.
- the inner part 40 is attached to the movable Hubfederrahmen 34.
- the outer part 39 is fixed to the upper spring 37.
- the inner part 40 can be moved in the outer part 39.
- the heald 38 is decoupled in position A and is in the Tieffach.
- the movable Hubfederrahmen 34 is in the lower position.
- the inner sliding part 40 inserted in the outer sliding part 39, in the upper area.
- the lower spring 36, and the upper spring 37 each set with a length of X.
- the preload and the spring force are the same in this example.
- the Hubfederrahmen 34 has gone up by the distance of 2 X, the spring 36, and 37 was stretched to 2 X each.
- the difference between thread eye 23, in the Tieffach and thread eye 23 in the high box is X.
- the heald 38 is coupled 41 in the high box to the stationary locking element 14.
- the Hubfederrahmen 34 is driven by the distance 2 X down.
- the inner sliding part 40 in the outer sliding part 39, by the distance X, has moved down.
- the spring 37 has also moved down the distance X to the basic dimension X down. Since in position C, the heald 38 is coupled to the stationary locking element 14, by means of the coupling point 42, the heald 38 has remained in the high bay. If now no sliding element would be additionally interposed, the stroke of the movable Hubfederrahmens of 2 X could not be picked up by the stretched spring 37.
- the stretched spring 37 could only take a stroke of X.
- the sliding element thus has the task of compensating for part of the stroke of the lifting spring frame 34.
- the spring itself could serve as an outer sliding part into which the inner sliding part can dip.
- the FIG. 7 described sliding elements are suitable for all machine designs according to the invention and Hubfederrahmen. With appropriate selection of the spring lengths and spring forces can be worked without sliding part.
- FIG. 8 shows the movement of the Hubfederrahmen with the positioning of the healds in the high and low shed. Furthermore, the position change described the healds is shown by spring force. So that the healds can not get into vibration and unrest beyond the high and low-fold position due to the elasticity of the springs, it makes sense to work with a corresponding stop. (see also FIG. 3 , and FIG. 9 ). Thus, the upper and lower end position of the healds safely and reproducibly determined and guaranteed.
- a suitable stop system for the healds can also be integrated into the fixed locking element or provided elsewhere. This exact shed limiting by means of stop system makes the two different shifts in combination only possible because the healds must not be in motion before switching by spring force.
- FIG. 9 shows an overview with two movable Hubfederrahmen (17,18), with heddles (25, 26), with thread eyes (23,24), with fixed locking element (14) and with integrated coupling points (27,28,29,30), further with adjustable stop strips (41,42), and with corresponding stop (43) on the healds.
- the stop strips together with the stop points on the healds a precise limitation or determination of the stroke of the Hedges possible.
- an exactly adjustable downtime of the healds can be realized. See also FIG. 8 , The downtime of healds has a positive effect on the flow of weft insertion in the loom.
- FIG. 8 The downtime of healds has a positive effect on the flow of weft insertion in the loom.
- the Hubfederrahmen are below.
- the heald is decoupled, and is therefore in the Wegfach.
- the upper and lower springs are equally taut.
- the Hubfederrahmen stand above.
- the heald is decoupled, and is therefore in the high compartment.
- the upper and lower springs are equally taut.
- the Hubfederrähmen are below.
- the heald is coupled, and is therefore in the high compartment.
- the upper spring is compressed accordingly, and the lower spring is correspondingly more tense.
- the Hubfederrahmen stand above.
- the heald is coupled, and is therefore in the Tieffach.
- the upper spring is correspondingly more tense and the lower spring is compressed accordingly.
- the in the Figures (3 . 4 . 5 . 6 . 7 . 8th . 9 ) described constructions can also work with so-called inclined tray.
- the movable Hubfederrahmen (17,18) can be divided into shaft-like elements, which then make to achieve a sloping tray obliquely in the warp direction increasing each more stroke than the front shaft-like elements.
- a uniform maximum stroke can be set for all Hubfederrahmen.
- An inclined tray can then be achieved by differently set stop strips.

Abstract
Description
Die Erfindung betrifft eine Fachbildevorrichtung für die Textiltechnik mit Einzelfadensteuerung (Jacquardtechnik), welche mit je einer Feder am oberen und unteren Ende der Weblitze in sogenannter Offenfacharbeitsweise bei 180° Umdrehung der Fachbildevorrichtung je Webschusseintrag arbeitet, wobei diese Arbeitsweise durch zwei eng beieinander liegende unterschiedliche Funktions- und Schaltabläufe erst möglich wird. Der obere und untere Hubfederrahmen mit den Federn bewegt sich im Webschusseintragstakt von oben nach unten und von unten nach oben usw. Ein ortsfestes Arretierelement kann dann in Offenfacharbeitsweise mustergerecht die Weblitzen im Hoch- bzw. im Tieffach arretieren und entarretieren (koppeln und entkoppeln). Auf den sogenannten Webharnisch wird verzichtet.The invention relates to a shed forming device for textile technology with monofilament control (jacquard technique), which works with one spring at the top and bottom of the heddle in so-called Offenfacharbeitsweise at 180 ° rotation of the shedding device per weft insertion, this operation by two closely spaced different functional and switching processes is only possible. The upper and lower Hubfederrahmen with the springs moves in Webschusseintragstakt from top to bottom and from bottom to top, etc. A stationary locking element can then lock the healds in high and low depth in the open shed example pattern and unlock (couple and decouple). The so-called Webharnisch is waived.

Nach dem Stand der Technik ist ferner in der Gebrauchsmusterschrift
Bei dieser Arbeitsweise wird das System (es handelt sich um ein sogenanntes Schwingsystem) in permanente Schwingung versetzt, so dass die Weblitze diese Schwingung mitmacht und den Weg von Tief nach Hoch und umgekehrt macht. Soll die Weblitze im Tief- oder Hochfach verharren, soll sie entsprechend durch eine Haltevorrichtung gehalten werden.
Diese Arbeitsweise hat den gravierenden Nachteil, dass die Weblitzen mittels der Schwingvorrichtung für jeden Webschuss immer den kompletten Weg Tief-Hoch-Tief, bzw. Hoch-Tief-Hoch machen müssen, da andernfalls die muster- und bindungsgerechte Position der Weblitzen nicht erreicht werden kann. Es ist also immer eine komplette Schwingung von 360° pro Webschusseintrag erforderlich.In this mode of operation, the system (it is a so-called oscillating system) is set in permanent oscillation, so that the healse joins in this oscillation and makes the way from low to high and vice versa. If the heddle should remain in the deep or high compartment, it should be held by a holding device accordingly.
This mode of operation has the serious disadvantage that the healds always have to make the complete path deep-high-low, or high-low-high by means of the oscillating device for each web shot, since otherwise the pattern and binding-appropriate position of the healds can not be achieved , So there is always a 360 degree swing required per hoop entry.
Die sogenannte Offenfacharbeitsweise, bei welcher die Hubelemente je Webschusseintrag immer nur den Weg von Tief nach Hoch, und für den nächsten Webschuss von Hoch nach Tief machen müssen, also nur einen Hubweg von 180°, ist bei dieser Arbeitsweise nicht möglich.The so-called Offenfacharbeitsweise, in which the lifting elements per weft insertion always only the way from low to high, and must make for the next web shot from high to low, so only a stroke of 180 °, is not possible in this operation.
Der erfindungsgemäße, gravierende Unterschied der zwei kombiniert arbeitenden Schaltsysteme bzw. Funktionsabläufe in Offenfacharbeitsweise mit nur 180° Hubweg der Hubelemente je Webschusseintrag, gegenüber der Gebrauchsmusterschrift
Ohne die erfindungsgemäß eng beieinander liegenden unterschiedlichen Funktions- und Schaltabläufe ist ein Arbeiten mit 180° Maschinenumdrehung je Webschusseintrag nicht möglich. Diese speziellen Funktions- und Schaltabläufe unterscheiden sich dadurch, dass die Weblitzen teilweise durch die Hubelemente (Hubfederrahmen) in ihre jeweilige Hoch- bzw. Tiefposition gebracht werden, und teilweise nur durch die freiwerdende jeweilige Federkraft direkt in die Hoch- bzw. Tiefposition gebracht werden. Welcher dieser beiden unterschiedlichen Schaltabläufe jeweils realisiert wird, ist von der jeweiligen Gewebebindung abhängig. Diese erfindungsgemäße spezielle und kombinierte Arbeitsweise ist absolut neu und in der Textiltechnik unbekannt.
Ein weiterer gravierender Unterschied liegt darin, dass die erfindungsgemäße Arbeitsweise mit Hubelementen (Hubfederrahmen) arbeitet, die einen exakt reproduzierbaren Hubweg und eine exakt reproduzierbare Hubzeit realisieren, was bei

Aufgabe der vorliegenden Erfindung war es, für das sogenannte "Jacquardweben" mit Einzelfadensteuerung eine Fachbildevorrichtung bereit zu stellen, welche in Offenfacharbeitsweise arbeitet und die Hubelemente (Hubfederrahmen) für jeden Webschusseintrag nur einen Hubweg von 180° machen, und wodurch selbstverständlich eine wesentlich höhere Webschusseintragszahl/Zeiteinheit erreicht werden kann; als bei einer Arbeitsweise mit 360° Hubweg der Hubelemente je Webschusseintrag. Entgegen den bekannten Fachbildevorrichtungen mit Arbeitsweise nach dem sogenannten Offenfachprinzip und 180° Umdrehung/Webschusseintrag der Fachbildevorrichtung mit zwei gegenläufig arbeitenden Hubelementen für die Hoch- und Tiefposition, wird erfindungsgemäß nur ein Hubelement für die Hoch- und Tiefposition benötigt. Unter Einsatz der erfindungsgemäßen unterschiedlichen Funktions- und Schaltabläufe kann trotzdem nach dem sogenannten Offenfachprinzip und 180° Umdrehung der Fachbildevorrichtung je Webschusseintrag gearbeitet werden.Object of the present invention was to provide for the so-called "jacquard" with monofilament control a shedding device that works in Offenfacharbeitsweise and make the lifting elements (Hubfederrahmen) for each Webschusseintrag only a stroke of 180 °, and which, of course, a much higher Webschustragtragszahl / Time unit can be achieved; as in a mode of operation with 360 ° stroke of the lifting elements per weft insertion. Contrary to the known shedding devices with operation according to the so-called open shed principle and 180 ° rotation / Webschusseintrag the shedding device with two counter-rotating lifting elements for the high and low position, only one lifting element for the high and low position is required according to the invention. Using the different functional and Switching operations can nevertheless be carried out according to the so-called open compartment principle and 180 ° rotation of the shedding device per weft insertion.
Ferner sollte die vorliegende Erfindung ohne Webharnisch arbeiten, möglichst einfach und sicher arbeiten, und kostengünstig mit nur einer Arretiervorrichtung je Weblitze auskommen. Diese Aufgabe wird durch eine Fachbildevorrichtung gelöst, welche erfindungsgemäß mit je einer Feder am oberen und unteren Ende der Weblitze arbeitet. Die Federn sind an einem unteren und oberen Hubfederrahmen befestigt. Die Weblitzen werden durch ein ortsfestes Arretierelement mustergerecht im Hoch bzw. Tieffach gekoppelt. Der obere und untere Hubfederrahmen mit den Federn bewegt sich richtungsgleich im Webschusseintragstakt von oben nach unten und von unten nach oben usw., so dass die Arretiervorrichtungen (wie oben beschrieben) die Weblitzen im Hoch- bzw. im Tieffach mustergerecht koppeln können.Furthermore, the present invention should work without Webharnisch work as simple and safe, and cost to get by with only one locking device per heald. This object is achieved by a shedding device which operates according to the invention, each with a spring at the top and bottom of the heald. The springs are attached to a lower and upper Hubfederrahmen. The healds are coupled by a stationary locking element pattern in the high or low compartment. The upper and lower Hubfederrahmen with the springs moves the same direction in Webschusseintragstakt from top to bottom and from bottom to top, etc., so that the locking devices (as described above) can match the healds in the high and low depth pattern.

Es sind jeweils nur zwei Weblitzen mit je einem Kettfaden gezeichnet, die stellvertretend für eine beliebige Anzahl von Weblitzen und Kettfaden stehen
Die beweglichen Hubfederrahmen 17,18, stehen in unterer Position. Die Weblitze 25, ist entkoppelt, und hat sich demzufolge mit den beiden Hubfederrahmen 17,18, und den daran befestigten Federn 19,21, nach unten in das Tieffach bewegt. Die Federn stehen dabei in einer gewissen Vorspannung, damit die Weblitze sicher und ruhig geführt und bewegt werden kann, und damit die geforderte Webfachöffnung stabil und sicher und reproduzierbar erreicht werden kann. Die Weblitze 26, wurde vor dem Absenken der Hubfederrahmen 17,18, an der Koppelungsstelle 29, an das ortsfeste Arretierelement 14, gekoppelt. Die Weblitze 26, ist demzufolge im Hochfach geblieben. Aufgrund dieser Koppelung 29, wird bei der Abwärtsbewegung der Hubfederrahmen 17,18, die Feder 20, gedehnt, und die Feder 22, wird zusammengedrückt. Die Federn müssen zu diesem Zwecke lang genug sein, und sie müssen so gewickelt sein, dass sie sich um das erforderliche Maß zusammendrücken lassen. Die gleichgerichtete Auf- und Abbewegung der Hubfederrahmen 17, 18, ist durch die seitlichen vertikalen Richtungspfeile gekennzeichnet. Die verstellbaren Anschlagleisten 41, 42, dienen der exakten Begrenzung und Positionsbestimmung der Weblitzen im Hoch- und im Tieffach.There are only two heddles each drawn with a warp thread, which are representative of any number of heddles and warp

Da für den zweiten Webschuss die Weblitze 26, in das Tieffach wechseln soll, muss die Koppelung 28, noch vor der Aufwärtsbewegung der Hubfederrahmen 17,18, entkoppelt werden. Die Folge davon ist, dass die Weblitze 26, durch die Federkraft der Feder 20, nach unten gezogen wird, (siehe hierzu A.2). Sobald die Weblitze 26, in das Tieffach gewechselt hat, wird sie sofort wieder gekoppelt (siehe Koppelung 30), allerdings an einer anderen Weblitzenstelle. Nun bewegen sich die Hubfederrahmen 17,18, nach oben, (siehe hierzu B.1). Die Weblitze 25, ist entkoppelt, und hat sich demzufolge mit den beiden Hubfederrahmen 17,18, und den daran befestigten Federn 19,21, nach oben in das Hochfach bewegt, (siehe hierzu B.1). Die Weblitze 26, ist aufgrund der Koppelung 30, im Tieffach geblieben. Aufgrund dieser Koppelung 30, wird bei der Aufwärtsbewegung der Hubfederrahmen 17,18, die Feder 22, gedehnt, und die Feder 20, wird zusammengedrückt.
Da beim dritten Webschuss (siehe hierzu C.1) die Weblitze 25, im Hochfach bleiben soll, bleibt diese Weblitze 25, an der Koppelungsstelle 27, gekoppelt. (siehe hierzu B.2)
Da beim dritten Webschuss (siehe hierzu C.1) die Weblitze 26, in das Tieffach wechseln soll, bleibt diese Weblitze 26, entkoppelt. (siehe hierzu B.2) Sie kann damit beim nächsten Wechsel nach unten in das Tieffach bewegt werden.
Nun bewegen sich die Hubfederrahmen 17,18, nach unten, (siehe hierzu C.1). Die Weblitze 25, ist aufgrund der Koppelung 27, im Hochfach geblieben. Aufgrund dieser Koppelung 27, wird bei der Abwärtsbewegung der Hubfederrahmen 17,18, die Feder 19, gedehnt, und die Feder 21, wird zusammengedrückt.
Die Weblitze 26, ist entkoppelt, und hat sich demzufolge mit den beiden Hubfederrahmen 17,18, und den daran befestigten Federn 20,22, nach unten in das Tieffach bewegt, (siehe hierzu C.1).
Da beim vierten Webschuss (siehe hierzu D.1) die Weblitze 25, im Hochfach bleiben soll, bleibt die Koppelung 27, bestehen (siehe hierzu C.2).
Da beim vierten Webschuss die Weblitze 26, im Tieffach bleiben soll, wird die Koppelungsstelle 30, gekoppelt (siehe hierzu C.2).
Nun bewegen sich die Hubfederrahmen 17,18, nach oben, (siehe hierzu D.1). Die Weblitze 25, ist aufgrund der Koppelung 27, im Hochfach geblieben. Aufgrund der Aufwärtsbewegung der Hubfederrahmen 17,18, werden die Federn 19,21, in ihre Neutral- bzw. Normallänge gebracht. Die Weblitze 26, ist aufgrund der Koppelung 30, im Tieffach geblieben. Die Feder 22, wird gedehnt, und die Feder 20 wird zusammengedrückt, (siehe hierzu D.1).Since for the second web shot the

Da beim fünften Webschuss die Position vom ersten Webschuss wieder erreicht werden soll, (siehe hierzu A.1), wobei die Weblitze 25, in das Tieffach wechseln soll, wird diese Weblitze 25, entkoppelt, (siehe hierzu D.2), damit sie bei der folgenden Abwärtsbewegung der Hubfederrahmen in das Tieffach wechseln kann. Da die Weblitze 26, beim nächsten Webschuss (siehe hierzu A.1) in das Hochfach wechseln soll, wird die Koppelungsstelle 30, entkoppelt.(siehe hierzu D.2) Die Folge ist, dass die Weblitze 26, durch die Federkraft der Feder 22, sofort in das Hochfach gezogen wird. Hier wird sie dann an die Koppelungsstelle 28 gekoppelt. (siehe hierzu D.2)
Nun bewegen sich die Hubfederrahmen 17,18, nach unten, (siehe hierzu A.1). Die entkoppelte Weblitze 25, wechselt dadurch in das Tieffach.
Die Weblitze 26, ist aufgrund der Koppelung 28, im Hochfach geblieben (siehe hierzu A.1). Die Feder 20, wird hierbei gedehnt, und die Feder 22, wird zusammengedrückt.Since the position of the first web shot is to be reached again at the fifth web shot (see A.1), whereby the

Diese exakte Webfachbegrenzung mittels Anschlagsystem macht die beiden unterschiedlichen Schaltvorgänge in Kombination erst möglich, da die Weblitzen vor dem Schaltvorgang mittels Federkraft nicht in Bewegung sein dürfen.
This exact shed limiting by means of stop system makes the two different shifts in combination only possible because the healds must not be in motion before switching by spring force.

- A shedding device with individual thread control for textile technology, with a fixed locking element (14) for coupling and uncoupling the healds (25, 26') to and from the fixed locking element (14), characterized in that
the movement of the healds (25, 26) into the upper shed or into the lower shed takes place with the aid of two different, but mutually complementary systems, the first system operating with at least one movable lifting spring frame (17, 18, 34) and with the springs (19, 20, 21, 22) fastened to it, and the second system moving the healds into the upper or into the lower shed by means of spring force only, the leasing position for the pattern-consistent coupling and uncoupling of the healds being capable of taking place in the upper shed and in the lower shed for both systems, and the pattern-consistent leasing and the coupling and uncoupling being capable of taking place together with only one actuator for each heald for both systems, the open-shed type of operation being capable of taking place with a stroke travel of the lifting spring frame of only 180° for each weft insertion. - The shedding device as claimed in claim 1, characterized in that a movable lifting spring frame (17) arranged at the bottom is used as a lifting element with springs (19, 20) fastened to it and a movable lifting spring frame (18) arranged at the top is used as a lifting element with springs (21, 22) fastened to it.
- The shedding device as claimed in one of claims 1 and 2, characterized in that the healds (25, 26) are connected with their lower end in each case to the upper end of the springs (19, 20), and in that the healds (25, 26) are connected with their upper end in each case to the lower end of the springs (21, 22).
- The shedding device as claimed in one of claims 1 to 3, characterized in that the healds (25, 26) can be coupled and uncoupled above the thread loops (23, 24) and/or below the thread loops (23, 24) by means of a fixed locking element (14).
- The shedding device as claimed in one of claims 1 to 4, characterized in that the pattern-consistent leasing and selection operation is to be divided into and implemented in two different functional sequences lying closely to one another, one functional sequence moving the healds into the upper or lower shed by means of the lifting elements, and the other functional sequence moving the healds, after uncoupling has taken place, directly into the upper shed or the lower shed by means of the associated spring by the spring force only.
- The shedding device as claimed in one of claims 1 to 5, characterized in that only one of the two lifting spring frames (17 or 18) is movable and executes the required stroke, low/high/low/high, etc., and the other opposite spring frame (33) is installed at a fixed location and does not execute any lifting movement.
- The shedding device as claimed in one of claims 1 to 6, characterized in that the springs (19, 20, 21, 22) used are produced from metal and/or are designed as pneumatic springs and/or as hydraulic springs and/or the like.
- The shedding device as claimed in one of claims 1 to 7, characterized in that it may also operate with what is known as an oblique shed, the movable lifting spring frames (17, 18, 34) being divided into shaft-like elements which then, to achieve an oblique shed, execute, ascending in the warp direction, in each case a greater stroke than the front shaft-like elements, and/or in that the settable abutment systems for limiting the heald stroke are set differently such that the rear heald rows, ascending, execute a greater stroke than the front heald rows.
- The shedding device as claimed in one of claims 1 to 8, characterized by sliding elements (39, 40) arranged between the fixed locking element (14) and the movable lifting spring frame for compensating a part of the stroke travel.
- The shedding device as claimed in one of claims 1 to 9, characterized in that work is carried out with abutment systems (41, 42, 43) which are suitable for limiting and controlling the stroke travel of the healds in the upper and the lower shed.
