Several such bags are arranged beside one another in a textile web, and the dobby fabric (6) joining the front (10) and rear (11) of the bag has a central selvedge (1) for separating the bags. The dobby fabric (8) closing the bag off at the bottom forms one continuous edge of the textile web and the top strips (2) form the other continuous open edge. In the process, a textile web for bags is produced on a power or automated loom with a dobby in a continuous production cycle with shaft threading in of three repeating groups.

Description

Die Erfindung betrifft einen Sack aus textilem Material, der aus einem Hohlgewebe gebildet ist, dessen zwei übereinanderliegende, Vorderseite und Rückseite des Sackes bildende Gewebelagen seitlich sowie bodenseitig jeweils durch ein Schaftgewebe miteinander verbunden sind, eine Gewebebahn für Säcke, die ein Doppelgewebe umfaßt, das in Richtung der Kettfäden am einen Rand ein die beiden Lagen des Doppelgewebes verbindendes, durchgehendes Schaftgewebe aufweist und das in Richtung der Schußfäden jeweils in der Sackbreite entsprechenden Abständen mit die beiden Lagen des Doppelgewebes verbindenden, Schnittleisten umfassenden Schaftgewebestreifen versehen ist, und ein Verfahren zur Herstellung einer Gewebebahn für Säcke auf einer herkömmlichen Webmaschine oder auf einem mit einer Schaftmaschine ausgestatteten Webautomaten in einem Produktionsgang.The invention relates to a sack made of textile material, which is formed from a hollow fabric, the two superposed fabric layers forming the front and back of the sack are laterally and bottom connected to each other by a shaft fabric, a fabric sheet for sacks, which comprises a double fabric, the Direction of the warp threads at one edge has a continuous shaft fabric connecting the two layers of the double fabric and the shaft fabric strips comprising cutting strips comprising cutting strips and connecting the two layers of the double fabric in the direction of the weft threads, and a method for producing a fabric sheet for sacks on a conventional weaving machine or on a weaving machine equipped with a dobby in one production run.

Es wurden zur Lagerung und Beförderung von Obst und Gemüse und dgl. bis jetzt üblicherweise entweder Säcke mit lockerer Webart aus Kunststoffgrundmaterialien oder aus üblichen natürlichen Grundmaterialien in dichter Webart hergestellt.For storage and transportation of fruits and vegetables and the like. Up to now, either sacks with a loose weave made of plastic base materials or from normal natural base materials in dense weave have usually been produced.

Produktionsverfahren für Säcke, die aus Kunststoffgrundmaterialien, z.B. aus Kunststoffolien oder durch Verstricken von Kunststoffäden auf Strickmaschinen, hergestellt werden, sind heute sehr häufig, aber mit Rücksicht darauf, daß das Verbinden der Ränder der einzelnen Säcke dabei auf thermischem Wege erfolgt, eignen sich solche Verfahren nicht für die Herstellung von Säcken aus natürlichen Textilmaterialien, z.B. aus 100% Baumwolle. Besonders aus Umweltschutzgründen wäre aber gerade die Produktion von Säcken aus natürlichen, verbrenn- und kompostierbaren Textilmaterialien sehr wünschenswert.Production processes for sacks made from plastic base materials, e.g. made of plastic films or by knitting plastic threads on knitting machines are very common today, but considering that the edges of the individual bags are connected thermally, such processes are not suitable for the production of bags from natural textile materials , e.g. 100% cotton. Especially for environmental reasons, the production of sacks from natural, combustible and compostable textile materials would be very desirable.

Ein Produktionsverfahren von Säcken aus textilem Material, das aus natürlichem Grundmaterial besteht, erfolgt in herkömmlicher Weise in drei Phasen:

  • 1. Stricken des Materials für den Sackkörper auf speziellen Raschel-Strickmaschinen.
  • 2. Zuschnitt (Konfektionierung) des Sackkörpers entsprechend den gewünschten Maßen aus dem gestrickten Material.
  • 3. Zusammennähen der Säcke und Vernähen der Ränder.
A production process for bags made of textile material, which consists of natural base material, takes place in a conventional manner in three phases:
  • 1. Knitting the material for the sack body on special Raschel knitting machines.
  • 2. Cutting (assembly) of the bag body according to the desired dimensions from the knitted material.
  • 3. Sew the bags together and sew the edges together.

Aus der EP 0 408 467 A1 ist auch ein Verfahren zur Herstellung von gewebten Säcken auf einer herkömmlichen Webmaschine mit einer Schaftsteuerung für die Kettfäden zur Erzielung einer Dreherbindung bekannt. Nach diesem Verfahren wird ein Doppelgwebe hergestellt, dessen zwei aus Drehergeweben bestehende, übereinanderliegende und voneinander getrennte Lagen durch Verschlingung ihrer jeweiligen Kett- und Schußfäden entlang einer Kante in Kettfadenrichtung und über die ganze Breite in festgelegten Abständen in Schußfadenrichtung miteinander verbunden sind. Hierbei wird eine zusammenhängende Bahn aufeinanderfolgender Säcke erhalten, die miteinander in Querrichtung sowie entlang einer Webkante verbunden sind, wobei die andere Webkante offen bleibt. Eine derartige Sackbahn eignet sich zum automatischen Befüllen der Säcke, wobei die Trennung der Säcke voneinander nach Befüllen und Verschließen derselben längs der Mitte des jeweiligen Querverbindungsbereiches erfolgt.EP 0 408 467 A1 also discloses a method for producing woven bags on a conventional weaving machine with a shaft control for the warp threads in order to achieve a leno weave. According to this process, a double weave is produced, the two layers of leno, one above the other and separated from each other, are connected to each other by interlacing their respective warp and weft threads along an edge in the warp thread direction and over the entire width at fixed intervals in the weft thread direction. Here, a coherent web of successive sacks is obtained which are connected to one another in the transverse direction and along one selvedge, the other selvedge remaining open. Such a sack track is suitable for the automatic filling of the sacks, the sacks being separated from one another after the sacks have been filled and closed along the center of the respective cross-connection area.

Aufgabe der Erfindung ist nun ebenfalls die Schaffung eines Sackes aus textilem Material sowie einer Gewebebahn in Form einer Rollenware für solche Säcke. Dabei sollen die Säcke bzw. die Gewebebahn auf einfache Weise und kostengünstig herstellbar sein, wobei die Säcke auch leicht handhabbar sein und sich zudem gut für eine maschinelle Befüllung eignen sollen.The object of the invention is now also to create a sack made of textile material and a fabric web in the form of a roll for such sacks. The sacks or fabric web should be simple and inexpensive to produce, the sacks should also be easy to handle and should also be well suited for machine filling.

Der Sack ist gemäß der Erfindung dadurch gekennzeichnet, daß die beiden Vorderseite und Rückseite des Sackes bildenden Gewebelagen oben jeweils mit aus einem Schaftgewebe bestehenden Randleisten versehen sind, wobei das seitlich angeordnete, die Vorderseite und Rückseite des Sackes verbindende Schaftgewebe sich vom bodenseitigen Schaftgewebe bis mindestens an die Randleisten erstreckt.The sack is characterized according to the invention in that the two layers of fabric forming the front and back of the sack are each provided at the top with edge strips consisting of a shaft fabric, the shaft fabric arranged laterally and connecting the front and back of the sack extending from the bottom shaft fabric to at least one extends the sidebars.

Der vorzugsweise aus natürlichem Textilmaterial auf einer herkömmlichen Webmaschine oder einem Webautomaten mit einer Schaftmaschine in einem Produktionsgang zu fertigende Sack hat eine gute Haltbarkeit und ein ansprechendes Aussehen, umsomehr als der Sackkörper selbst auch ganz leicht mit verschiedensten Mustern gewebt werden kann. Die Sackränder und Kanten fransen nicht aus und weisen überdies keine Nähte auf, die aufgehen können. Die gewebten Säcke bedürfen keiner Konfektionierung und die vom Webstuhl abgenommenen, fertigen Säcke können sofort zum Befüllen verwendet werden.The preferably made of natural textile material on a conventional weaving machine or a weaving machine A sack to be produced in a dobby in one production cycle has a good durability and an attractive appearance, all the more so since the sack body itself can also be woven very easily with a wide variety of patterns. The bag edges and edges do not fray and, moreover, have no seams that can open. The woven bags do not need to be assembled and the finished bags removed from the loom can be used immediately for filling.

Der erfindungsgemäße Sack ist ferner dadurch gekennzeichnet, daß in seinen Randleisten Handgrifföffnungen angeordnet oder Verschlußbänder vorgesehen oder eingewebt sind.The sack according to the invention is further characterized in that handle openings are arranged in its edge strips or closure straps are provided or woven.

Nach einem weiteren Merkmal der Erfindung ist der Sack dadurch gekennzeichnet, daß seine Vorder- und Rückseite aus einem Gewebe von lockerer Webart und das die beiden Gewebelagen seitlich und bodenseitig verbindende Schaftgewebe sowie das die oberen Randleisten bildende Schaftgebe von dichter Webart ist. Daraus ergibt sich nicht nur ein gefälliges Aussehen des Sackes, sondern der Sackkörper selbst ist dadurch auch ausreichend luftdurchlässig und die Ränder des Sackes sind stabil und nichtfransend.According to a further feature of the invention, the sack is characterized in that its front and rear sides are made of a loose weave and the shaft fabric connecting the two fabric layers on the side and bottom, as well as the dense weave forming the upper marginal ridges. This not only results in a pleasing appearance of the sack, but the sack body itself is also sufficiently permeable to air and the edges of the sack are stable and non-fraying.

Die Erfindung umfaßt auch eine Gewebebahn für Säcke, die dadurch gekennzeichnet ist, daß das Doppelgewebe der Gewebebahn am anderen Rand seine beiden Lagen jeweils begrenzende Randleisten aus Schaftgewebe aufweist und daß die die beiden Lagen des Doppelgewebes verbindenden Schnittleisten vom durchgehenden, am einen Rand angeordneten Schaftgewebe bis zumindest an die am anderen Rand vorgesehenen, die beiden Lagen des Doppelgewebes jeweils begrenzenden Randleisten reichen.The invention also encompasses a fabric web for sacks, which is characterized in that the double fabric of the fabric web has edge strips of shaft fabric that delimit its two layers at the other edge, and that the cutting strips connecting the two layers of the double fabric extend from the continuous shaft fabric arranged at one edge to at least to the edge strips provided on the other edge, each delimiting the two layers of the double fabric.

Eine solche Gewebebahn, insbesondere aus natürlichem textilem Material, wie beispielsweise Baumwolle, ist auf einem herkömmlichen Webstuhl oder einem Webautomaten mit Schaftmaschine als Rollenware, bestehend aus einer großen Anzahl von Säcken auch technologisch gesehen in sehr vorteilhafter Weise herstellbar. Abhängig vom Verwendungszweck kann die Gewebebahn sofort an den Schnittleisten in Stücke geschnitten werden, um so einzelne Säcke zu erhalten oder im Fall großindustriellen oder großbetrieblichen Einsatzes kann die als Rolle gelagerte Gewebebahn gleich einer automatischen Füllmaschine zur Befüllung der Säcke zugeführt werden. Nach dem Füllen eines Sackes wird dieser durch Vernähen der Randleisten bzw. Sacklaschen oder mittels in den Randleisten vorgesehener Verschlußbänder verschlossen und von der Gewebebahn an der Schnittleiste, z.B. mittels mechanischer Rollenmesser abgetrennt.Such a fabric web, in particular made of natural textile material, such as cotton, can also be produced in a very advantageous manner from a technological point of view on a conventional loom or a weaving machine with a dobby as a roll, consisting of a large number of sacks. Depending on the intended use, the fabric web can be cut into pieces immediately at the cutting strips in order to obtain individual sacks or in the case of large-scale industrial or large-scale use the fabric web stored as a roll is fed to an automatic filling machine for filling the bags. After a sack has been filled, it is closed by sewing the edge strips or sack flaps or by means of fastening strips provided in the edge strips and separated from the fabric web on the cutting strip, for example by means of a mechanical roller knife.

Eine Gewebebahn kann, vor allem von den Möglichkeiten eines Webstuhles abhängig, erfindungsgemäß zwei oder mehrere wie oben angegeben ausgebildete Gewebebahnen umfassen, in welchem Fall aber die eine zur jeweils benachbarten anderen spiegelbildlich angeordnet ist. Vorliegendenfalls bilden dann die in Kettfadenrichtung verlaufenden Schaftgewebestreifen gleichzeitig auch Schnittleisten.Depending on the possibilities of a loom, a fabric web can comprise two or more fabric webs configured as indicated above, in which case, however, one is arranged in mirror image to the respectively adjacent one. In the present case, the shaft fabric strips running in the warp thread direction also form cutting strips at the same time.

Die Erfindung betrifft auch ein Verfahren zur Herstellung einer Gewebebahn für Säcke, das dadurch gekennzeichnet ist, daß kontinuierlich durch in drei, sich jeweils wiederholende Gruppen erfolgende Schafteinfädelung in der ersten Gruppe an einem offen bleibenden Rand der ein Doppelgewebe umfassenden Gewebebahn in Richtung der Kettfäden verlaufend die beiden Lagen des Doppelgewebes begrenzende Randleisten aus Schaftgewebe, in der zweiten Gruppe das das Körpermaterial eines Sackes bildende Doppelgewebe sowie die in regelmäßigen Abständen erfolgende Verbindung der beiden Doppelgewebelagen in Form eines sich normal zu den Rändern des Doppelgewebes und in Richtung der Schußfäden sich erstreckenden, jeweils eine die Säcke trennende Schnittleiste umfassenden Schaftgewebestreifens und in der dritten Gruppe am dem offen bleibenden Rand der Gewebebahn gegenüberliegenden anderen Rand in Richtung der Kettfäden verlaufend eine aus einem Schaftgewebe gebildete Verbindung der Doppelgewebelagen hergestellt wird.The invention also relates to a process for the production of a fabric web for sacks, which is characterized in that continuously in three, repeating groups of threading in the first group on an open edge of the fabric web comprising a double fabric, in the direction of the warp threads two layers of the double fabric delimiting marginal ridges made of shaft fabric, in the second group the double fabric forming the body material of a sack as well as the connection of the two double fabric layers, which takes place at regular intervals, in the form of a each extending normally to the edges of the double fabric and in the direction of the weft threads the sack-separating cutting strip comprising shaft fabric strip and in the third group on the other edge opposite the open edge of the fabric web running in the direction of the warp threads a connection of the double fabric formed from a shaft fabric is produced.

In wirtschaftlich und technologisch gesehen besonders vorteilhafter Weise erfolgt die Herstellung der Gewebebahn für Säcke und somit der Säcke selbst in einem Produktionsgang, wobei innerhalb der gesamten Gewebebreite drei Webvarianten aufscheinen, nämlich Hohlgewebe, Doppelgewebe und normales Schaftgewebe. Ein großer Vorteil liegt weiters darin, daß auf diesem Weg die Herstellung von Säcken schneller, als dies bisher möglich war, auch aus natürlichen, umweltfreundlichen Grundmaterialien erfolgen kann. Außerdem kann das Verfahren nach den Möglichkeiten der Funktion der Schaftmaschine in beliebigen Musterführungen verwirklicht werden, ohne daß dadurch höhere Produktionskosten verursacht würden. Daher sind so hergestellte Säcke nicht nur zur Lagerung und Beförderung von z.B. Obst und Gemüse einsetzbar, sondern auch für Dekorations- und Schmuckzwecke. Schließlich ist das erfindungsgemäße Produktionsverfahren hinsichtlich Material- und Energiebedarf günstiger als die herkömmlichen, mehrere Phasen umfassenden Herstellungsverfahren traditioneller Säcke.In an economically and technologically particularly advantageous manner, the fabric web for sacks and thus the sacks themselves are produced in one production step, with three weave variants appearing across the entire fabric width, namely hollow fabric, double fabric and normal shaft tissue. Another great advantage is that in this way the production of sacks can be made from natural, environmentally friendly basic materials faster than was previously possible. In addition, the method can be implemented according to the possibilities of the function of the dobby in any pattern guides, without causing higher production costs. Therefore, sacks made in this way can be used not only for the storage and transportation of, for example, fruit and vegetables, but also for decorative and decorative purposes. Finally, the production process according to the invention is cheaper in terms of material and energy requirements than the conventional, multi-phase manufacturing process for traditional sacks.

Ein weiteres Merkmal des erfindungsgemäßen Verfahrens besteht darin, daß die am einen Rand der Gewebebahn gebildete Verbindung der Doppelgewebelagen als durchgehender Schaftgewebestreifen und die am anderen Rand der Gewebebahn ihre beiden Lagen begrenzenden Randleisten als jeweils durchgehende, voneinander getrennt bleibende, Sacklaschen bildende Schaftgewebestreifen ausgebildet werden.Another feature of the method according to the invention is that the connection of the double fabric layers formed at one edge of the fabric web is formed as a continuous shaft fabric strip and the edge strips delimiting their two layers at the other edge of the fabric web are formed as continuous, woven bag fabric strips that remain separate from one another and form sack flaps.

Diese Ausbildung der Gewebebahn stellt nicht nur eine produktionstechnisch gesehen vorteilhafte Maßnahme dar, sondern vor allem die beiden Gewebelagen begrenzenden, jeweils durchgehenden, voneinander getrennt bleibenden Randstreifen bzw. Sacklaschen ermöglichen auf besonders einfache Weise eine komplikationslose Befüllung der Säcke mittels automatischer Füllmaschinen.This formation of the fabric web is not only a measure that is advantageous in terms of production technology, but also Above all, the two fabric layers delimiting, in each case continuous, edge strips or sack flaps that remain separate from one another enable the sacks to be filled in a particularly simple manner by means of automatic filling machines in a particularly simple manner.

Die Erfindung umfaßt auch ein Verfahren zur Herstellung einer zwei oder mehrere Bahnen für Säcke umfassenden Gewebebahn, die auf einer Webmaschine oder einem mit einer Schaftmaschine ausgestatteten Webautomaten in einem Produktionsgang kontinuierlich durch in drei, sich jeweils wiederholende Gruppen erfolgende Schafteinfädelung gemäß der für die Herstellung der eine Sackreihe umfassenden Gewebebahn angegebenen Verfahrensführung in nebeneinander spiegelbildlich sich wiederholender Form hergestellt wird, wobei in der Längsrichtung der Gewebebahn verlaufende Schnittleisten in den aneinandergrenzenden, in einem gewebten Schaftgewebestreifen und/oder Randstreifen gebildet werden.The invention also encompasses a process for the production of a fabric web comprising two or more webs for sacks, which on a weaving machine or a weaving machine equipped with a dobby is carried out continuously in one production step by threading in three, repetitive groups in accordance with the procedure for the production of the one The process line specified for the sack row comprising the fabric web is produced in a mirror-image repetitive form, with cutting strips running in the longitudinal direction of the fabric web being formed in the adjacent, in a woven shaft fabric strip and / or edge strips.

Der Gegenstand der Erfindung ist anhand der beigeschlossenen Zeichnungen beispielsweise näher erläutert, wobei Fig. 1 eine Patrone, Fig. 2 eine Draufsicht auf einen Abschnitt einer erfindungsgemäßen Gewebebahn, Fig. 3 eine Vorderansicht eines teilweise aufgebrochenen erfindungsgemäßen Sackes, Fig. 4 eine Schrägansicht auf einen Abschnitt einer erfindungsgemäßen, auseinandergezogenen Gewebebahn und Fig. 5 einen Schnitt entlang der Linie A - A durch die Gewebebahn gemäß Fig. 4 zeigen.The subject matter of the invention is explained in more detail, for example, with the aid of the accompanying drawings, in which FIG. 1 shows a cartridge, FIG. 2 shows a top view of a section of a fabric web according to the invention, FIG. 3 shows a front view of a partially broken bag according to the invention, and FIG. 4 shows an oblique view of one Section of an expanded fabric web according to the invention and FIG. 5 show a section along the line A - A through the fabric web according to FIG. 4.

Die Herstellung von Säcken bzw. einer Gewebebahn für Säcke erfolgt auf traditionellen Webmaschinen oder ist gemäß einer Weiterentwicklung auch auf modernen Webautomaten möglich, soferne der Webautomat mit einer Schaftmaschine ausgerüstet ist. Dabei kann die Steuerung der Webmaschine oder des mit einer Schaftmaschine ausgerüsteten Webautomaten sowohl mittels Lochkarten (Patronen) als auch mittels Computer (Mikroprozessor) erfolgen.The manufacture of sacks or a fabric web for sacks takes place on traditional weaving machines or, according to a further development, is also possible on modern weaving machines if the weaving machine is equipped with a dobby. The weaving machine or the weaving machine equipped with a dobby can be controlled both by punch cards (cartridges) and by computer (microprocessor).

Vorzugsweise werden die Säcke speziell im Hinblick auf Umweltverträglichkeitsgründen aus natürlichen, umweltfreundlichen Grundmaterialien, wie Baumwolle, Jute, Hanf, Flachs oder Leinen, Sisal, Wolle und dgl. Naturfasern, bevorzugter Weise jedoch aus 100% Baumwolle, hergestellt, so daß die nicht mehr verwendbaren und wegzuwerfenden Säcke, problemlos verbrannt oder kompostiert werden können. Daher werden derartige Säcke auch "Biosäcke" genannt.The bags are preferably more preferred, especially with regard to environmental compatibility reasons, from natural, environmentally friendly basic materials such as cotton, jute, hemp, flax or linen, sisal, wool and the like. Natural fibers However, made of 100% cotton, so that the no longer usable and disposable bags can be easily burned or composted. Such bags are therefore also called "organic bags".

Die Herstellung des Sackes bzw. der Gewebebahn erfolgt auf Schaftmaschinen mit Lochkartensteuerung entsprechend der Patrone gemäß Fig. 1, wobei das Weben von die Säcke voneinander trennenden Schnittleisten mittels gesonderter Kartensteuerung erfolgt. Aus der Lochkartenzeichnung und der nachfolgenden Angaben zur Produktionstechnologie ist ersichtlich, daß die Schafteinfädelung in Gruppen erfolgt, wobei vom Maß des Sackes abhängig ist, wie oft sich jeweils eine Gruppe wiederholt.The sack or fabric web is produced on dobby machines with punch card control corresponding to the cartridge according to FIG. 1, the cutting strips separating the sacks being woven by means of separate card control. From the punched card drawing and the following information on the production technology it can be seen that the shaft threading takes place in groups, the size of the sack depending on how often a group repeats itself.

Es gibt drei verschiedene Gruppen der Schafteinfädelung:

  • die erste Gruppe umfaßt die Sacklaschen bzw. oberen Randleisten des Sackes
  • die zweite Gruppe umfaßt das Körpermaterial des Sackes (Doppelgewebe) sowie die eine Schnittleiste umfassende Verbindung der Doppelgewebelagen, die die Säcke trennt
  • die dritte Gruppe umfaßt den Rand bzw. die Verbindung des Doppelgewebes an der Bodenseite des Sackes.
There are three different groups of shaft threading:
  • the first group comprises the sack flaps or upper edge strips of the sack
  • the second group comprises the body material of the sack (double fabric) as well as the connection of the double fabric layers comprising a cutting strip, which separates the sacks
  • the third group comprises the edge or the connection of the double fabric on the bottom side of the sack.

Zum Weben sind zehn Schäfte notwendig. Das Blattstechen erfolgt in Kammblättern von 140/10 cm mit vier Fäden. Die Hebung der Schäfte erfolgt aufgrund der Lochkartenlochung und die Wiederholung wird vom Maß des Sackes bestimmt.Ten shafts are required for weaving. Leaf pricking takes place in comb leaves of 140/10 cm with four threads. The shafts are lifted based on punched card punching and the repetition is determined by the size of the sack.

Das Besondere daran ist, daß während der eine Rand des Doppelgewebes geschlossen ist, der andere Rand des Gewebes offen ist und in der Mitte sich das Hohlgewebe befindet. Die so gewebten Säcke bedürfen keiner weiteren Konfektionierung und sind gleich ihrem Verwendungszweck zuführbar.The special thing about it is that while one edge of the double fabric is closed, the other edge of the fabric is open and the hollow fabric is in the middle. The sacks woven in this way do not require any further assembly and can be supplied for their intended use.

Die Fig. 2 und 4 zeigen einen Abschnitt einer Gewebebahn für Säcke, wobei quer zur Bahnlängsrichtung verlaufende, die Säcke voneinander trennende Schnittleisten 1 vorgesehen sind. An einem Rand der Gewebebahn sind durchgehende Sacklaschen bzw. Randleisten 2 angeordnet. Mit 3 ist der eigentliche Sackkörper bezeichnet und mit 4 ein Platz für Werbeaufschriften, an dessen Stelle aber auch eine Handgrifföffung vorgesehen sein kann. Die Randleisten 2 weisen im Bereich ihres Ansatzes an den Sackkörper 3 eine Stelle 5 für eine Vernähungsmöglichkeit eines gefüllten Sackes auf. Die Schnittleiste 1 befindet sich jeweils in der Mitte eines zusammengewebten Teiles 6 der beiden Lagen des Doppelgewebes, wobei der zusammengewebte Teil 6 jeweils durch Ränder 7 begrenzt ist. Am den Randleisten 2 gegenüberliegenden Rand der Gewebebahn ist ein durchgehender, die beiden Lagen der Bahn verbindender Gewebestreifen 8 angeordnet, wodurch die Säcke jeweils auch bodenseitig geschlossen sind.2 and 4 show a section of a fabric web for sacks, wherein cutting strips 1 running transversely to the longitudinal direction of the web and separating the sacks are provided. Continuous sack flaps or edge strips 2 are arranged on one edge of the fabric web. With 3 the actual bag body is designated and with 4 a space for advertising labels, but in its place a handle opening can also be provided. In the area of their attachment to the sack body 3, the edge strips 2 have a point 5 for the possibility of sewing a filled sack. The cutting bar 1 is located in the middle of a part 6 of the two layers of the double fabric woven together, the part 6 woven together being delimited by edges 7. A continuous fabric strip 8, which connects the two layers of the web, is arranged on the edge of the fabric web opposite the edge strips 2, as a result of which the bags are also closed at the bottom.

Mit 9 ist die Höhlung des Sackes bezeichnet, der eine Vorderseite 10 und eine Hinterseite 11 aufweist (Fig. 3 und 5).With 9 the cavity of the sack is designated, which has a front 10 and a rear 11 (Fig. 3 and 5).

Die Produktion des Sackes bzw. der Gewebebahn für Säcke erfolgt auf einem Webstuhl zu den bereits beschriebenen Bedingungen und abhängig von der Schaftmaschine in jeder beliebigen Musterung. Der Ablauf des Produktionsverfahrens ist, wie oben angegeben, derart, daß die Maschine aufgrund der in drei Gruppen erfolgenden Schafteinfädelung in der ersten Gruppe die Ausbildung der Sacklaschen bzw. Randleisten 2 mit dichter Webart als Begrenzung jeder der zwei Doppelgewebelagen am einen offen bleibenden Rand der Gewebebahn webt. In der zweiten Gruppe erfolgt das Weben des Sackkörpers 3 mit meist lockerer Webart in Form eines Doppelgewebes. Außerdem webt die Maschine aufgrund der ihr über die Lochkatenlochung gegebenen Anweisungen entsprechend den gewünschten Sackmaßen die Vorderseite 10 und die Hinterseite 11 des Sackes, d.h. die beiden Gewebelagen des Doppelgewebes, im Produktionsablauf zusammen, wobei zwischen den Rändern 7 der so sich bildenden zusammengewebten Teile 6 mit dichter Webart jeweils die Schnittleiste 1 gebildet wird, die die einzelnen Säcke voneinander trennt. Aufgrund der dritten Gruppe der Schafteinfädelung erfolgt laufend im Zuge der Produktion das Zusammenweben der zwei Gewebelagen am anderen, dem offen bleibenden Rand gegenüberliegenden Rand der Gewebebahn unter Bildung eines dicht gewebten Schaftgewebestreifens 8, der das Sackende verschließt. Im Bereich des Ansatzes an den Sackkörper 3 befinden sich in den Randleisten 2 bevorzugte Stellen 5, an welchen der Sack nach Befüllung zugenäht werden kann. Die Randleisten bieten auch einen Platz 4 für die Anbringung von Werbeausfschriften oder zur Anordnung von Handgrifföffnungen. Mittels dieses einheitlichen Produktionsverfahrens werden Säcke mit einer Sackhöhlung 9 erhalten. Zufolge des Produktionsablaufes wird mit der Webmaschine eine Gewebebahn als Rollenware bestehend aus einer großen Anzahl von Säcken erzeugt, wobei die Gewebebahn eine etwa der Sacktiefe entsprechende Breite, aber auch doppelte oder mehrfache Breite besitzen kann. Bei doppelter oder mehrfacher Breite sind etwa der Sacktiefe entsprechend breite Bahnen allerdings jeweils spiegelbildlich nebeneinander angeordnet, wobei sich dabei in der Längsrichtung der Gewebebahn verlaufende Schnittleisten (nicht dargestellt) in der Mitte aneinandergrenzender Schaftgewebestreifen 8 und/oder Sacklaschen bzw. Randstreifen 2 befinden. Eine doppelt oder mehrfach breite Gewebebahn wird vorzugsweise gleich, nachdem sie aus der Webmaschine kommt, entlang der längsverlaufenden Schnittleisten auseinandergeschnitten. Das Vorschriftsbeispiel C zur Produktionstechnologie betrifft die Herstellung einer doppelt breiten Gewebebahn, deren beide etwa der Sacktiefe entsprechend breiten Bahnen im Bereich des jeweils das verschlossene Sackende bildenden Schaftgewebestreifens 8 miteinander verbunden und an ihren beiden außen liegenden von den Sacklaschen bzw. den Randstreifen 2 gebildeten Längsrändern offen sind. Die aus der Webmaschine kommende Gewebebahn wird sogleich entlang der in der Mitte der miteinander verbundenen Schaftgewebestreifen 8 verlaufenden Schnittleiste mittels Rotiermesser auseinandergeschnitten.The sack or the fabric web for sacks is produced on a loom under the conditions already described and in any pattern depending on the dobby. The sequence of the production process is, as stated above, such that the machine, due to the threading in three groups in the first group, the formation of the sack flaps or edge strips 2 with a dense weave as a limitation of each of the two double fabric layers on an open edge of the fabric web weaves. In the second group, the sack body 3 is woven with a mostly loose weave in the form of a double fabric. In addition, the machine weaves the front 10 and the back 11 of the sack, ie the two fabric layers of the double fabric, in the production process based on the instructions given to it via the perforated card punching, with the between the edges 7 of the thus formed woven parts 6 with dense weave, the cutting bar 1 is formed, which separates the individual bags from each other. Because of the third group of shaft threading, the two fabric layers are continuously woven together on the other edge of the fabric web, opposite the edge that remains open, in the course of production, forming a tightly woven shaft fabric strip 8, which closes the end of the bag. In the area of the attachment to the sack body 3, there are preferred locations 5 in the edge strips 2, at which the sack can be sewn up after filling. The sidebars also offer space 4 for attaching advertising labels or for arranging handle openings. By means of this uniform production process, bags with a bag cavity 9 are obtained. As a result of the production process, the weaving machine is used to produce a roll of woven fabric consisting of a large number of bags, the woven web being able to have a width approximately equal to the depth of the bag, but also double or multiple widths. If the width is double or multiple, the depth of the sack is approximately the same However, wide webs are each arranged in mirror image next to one another, with cutting strips (not shown) running in the longitudinal direction of the fabric web being located in the middle of adjoining shaft fabric strips 8 and / or sack flaps or edge strips 2. A double or multiple width fabric web is preferably cut apart along the longitudinal cutting bars immediately after it comes out of the weaving machine. Regulation example C relating to production technology relates to the production of a double-wide fabric web, the two webs of which, approximately corresponding to the depth of the bag, are connected to one another in the region of the shaft fabric strip 8 forming the closed bag end and open at their two outer longitudinal edges formed by the bag flaps or the edge strips 2 are. The fabric web coming from the weaving machine is immediately cut apart along the cutting strip running in the middle of the interconnected shaft fabric strips 8 by means of a rotary knife.

Die im wesentlichen der Sacktiefe entsprechend breite Gewebebahn wird je nach Bedarf sofort bei den quer über die Bahn verlaufenden Schnittleisten 1 in Stücke geschnitten, um auf diese Weise gleich Einzelsäcke zur Verfügung zu haben, oder andernfalls zu Rollen aufgewickelt, in welcher Form dann auch die Lagerung erfolgen kann. Speziell bei großbetrieblichem oder großindustriellem Einsatz solcher Rollen eröffnet sich die Möglichkeit zur Füllung der Säcke mittels automatischer Füllmaschinen. Dabei wird jeweils nach Füllung eines Sackes dieser durch Vernähen der Sacklaschen bzw. Randstreifen 2 an der vorgesehenen Stelle 5 verschlossen und von der Gewebebahn an der Schnittleiste 1 mittels mechanischer Rotiermesser abgetrennt.The fabric web, which is essentially the same as the depth of the sack, is cut into pieces as required immediately with the cutting strips 1 running across the web, in order to have individual sacks available in this way, or else wound up into rolls, in which form the storage is then can be done. Especially with large-scale or large-scale industrial use of such rolls, it is possible to fill the sacks using automatic filling machines. After filling a sack, it is closed by sewing the sack flaps or edge strips 2 at the intended location 5 and separated from the fabric web on the cutting bar 1 by means of a mechanical rotary knife.
