- an internal warp thread is defined as that warp thread which is arranged on the longitudinal axis of the round fabric facing side of the weft thread.
- An outer warp thread is therefore defined as that warp thread which is arranged on the side facing away from the longitudinal axis of the round fabric side of the weft thread.
- the fabric of a round fabric made of weft thread and warp threads defines an interior and an exterior of the round fabric.
- the inner warp thread lies on the inner side of the weft thread, while the outer warp thread is arranged on the outer side of the weft thread.
- the number of warp threads forming a first group and the number of warp threads forming a second group are constant over the extension length of the round woven fabric.
- An example of a prior art round fabric is that the groups of outer warp yarns are formed by a warp yarn and the groups of inner warp yarns by two warp yarns. This system is maintained in round fabrics of the prior art over the entire length of the hose.
- the invention disclosed herein has as its object to provide a round fabric which, due to its structure, has round fabrics of different technical and also optical properties as round fabric according to the prior art.
- this is achieved by a first approach such that the number of internal warp threads which form a first group of internal warp threads and the number of internal warp threads which form a second group of internal warp threads are different, wherein the number of inner warp threads counted along a rounding of the weft thread lies in a range between one and the number n of the warp threads, and the number of outer warp threads is in each case in a range between zero and the number n of the warp threads.
- the above object can also be solved by a second approach that the number of outboard warp yarns forming a first set of outboard warp yarns and the number of outboard warp yarns forming a second set of warped warp yarns are different, wherein the number of inner warp threads counted along a rounding of the weft thread lies in a range between one and the number n of the warp threads, and the number of outer warp threads is in each case in a range between zero and the number n of the warp threads.

- All warp threads can be arranged lying horizontally to the weft thread.
- the number of weft threads arranged outside the weft thread can be zero in this case.
- the number of externally arranged warp threads can be n-1.
- the invention disclosed herein is based on the above-mentioned international patent application with the application number PCT / EP2016 / 069685 on.

Im Rahmen der Offenbarung der Erfindung sei ein innen liegender Kettfaden als jener Kettfaden definiert, der an der Längsachse des Rundgewebes zugewandten Seite des Schussfadens angeordnet ist. Ein außen liegender Kettfaden sei demzufolge als jener Kettfaden definiert, der an der der Längsachse des Rundgewebes abgewandten Seite des Schussfadens angeordnet ist.In the context of the disclosure of the invention, an internal warp thread is defined as that warp thread which is arranged on the longitudinal axis of the round fabric facing side of the weft thread. An outer warp thread is therefore defined as that warp thread which is arranged on the side facing away from the longitudinal axis of the round fabric side of the weft thread.
Durch das aus Schussfaden und Kettfäden hergestellte Gewebe eines Rundgewebes wird ein Inneres und ein Äußeres des Rundgewebes definiert. Der innen liegende Kettfaden liegt an der inneren Seite des Schussfadens, während der außen liegende Kettfaden an der äußeren Seite des Schussfadens angeordnet ist.The fabric of a round fabric made of weft thread and warp threads defines an interior and an exterior of the round fabric. The inner warp thread lies on the inner side of the weft thread, while the outer warp thread is arranged on the outer side of the weft thread.
Bei Rundgeweben nach dem Stand der Technik ist die Anzahl der eine erste Gruppe ausbildenden Kettfäden und die Anzahl der eine zweite Gruppe ausbildenden Kettfäden über die Erstreckungslänge des rundgewobenen Gewebes konstant. Ein Beispiel für ein Rundgewebe nach dem Stand der Technik ist, dass die Gruppen der außen liegenden Kettfäden durch einen Kettfaden und die Gruppen der innen liegenden Kettfäden durch zwei Kettfäden ausgebildet werden. Diese Systematik wird bei Rundgeweben nach dem Stand der Technik über die gesamte Länge des Schlauches beibehalten.In the case of prior art round fabrics, the number of warp threads forming a first group and the number of warp threads forming a second group are constant over the extension length of the round woven fabric. An example of a prior art round fabric is that the groups of outer warp yarns are formed by a warp yarn and the groups of inner warp yarns by two warp yarns. This system is maintained in round fabrics of the prior art over the entire length of the hose.

wobei die entlang einer Rundung des Schussfadens gezählte Anzahl der innen liegenden Kettfäden in einem Bereich zwischen Eins und der Anzahl n der Kettfäden liegen und die Anzahl der außen liegenden Kettfäden jeweils in einem Bereich zwischen Null und der Anzahl n der Kettfäden liegt.According to the invention, this is achieved by a first approach such that the number of internal warp threads which form a first group of internal warp threads and the number of internal warp threads which form a second group of internal warp threads are different,

Weiters kann durch die Anzahl der Kettfäden der Gruppen die Oberflächenstruktur des Schlauches vorgegeben werden. Die hier offenbarte Erfindung ist hierbei keinesfalls auf die Möglichkeit der ästhetischen Gestaltung der Oberfläche beschränkt, welche als ein zu erzielender Nebeneffekt angesehen werden kann.

Eine hohe Abriebfestigkeit kann auch dadurch erreicht werden, dass die Anzahl jener außen liegender Schussfäden einer Rundung, die eine Gruppe von Schussfäden ausbilden, n≥2 ist.A high abrasion resistance can also be achieved by the number of those outer weft threads of a rounding, which form a group of weft threads, being n≥2.
