Abstract

A belt, such as a round baler belt, includes an internal region, an external region, a core region arranged between the internal region and the external region, and at least one peripheral region arranged transversely to longitudinal direction of the round baler belt. The peripheral region is arranged at least partially between the internal region and the external region, and the belt is continuously closed in the longitudinal direction. The peripheral region may be arranged entirely between the internal region and the external region. In some cases, at least one peripheral region is two peripheral regions located opposite one another transversely to the longitudinal direction. Furthermore, the core region may be continuously wound, and even formed of reinforcing fabric. In some aspects, the internal region and/or the external region and/or a peripheral region and/or both peripheral regions contain an elastomeric material.

First claim

We claim:

1. A belt comprising an internal region, an external region, a core region arranged between the internal region and the external region, and at least one peripheral region arranged transversely to longitudinal direction of belt, wherein the peripheral region is arranged partially between the internal region and the external region, wherein the the belt is continuously closed in the longitudinal direction, and wherein core region is continuously wound without interruption in the longitudinal direction.

2. The belt according to claim 1 , wherein the at least one peripheral region is two peripheral regions located opposite one another transversely to the longitudinal direction.

3. The belt according to claim 1 , wherein the core region comprises a reinforcing fabric.

4. The belt according to claim 1 , wherein the internal region and/or the external region and/or a peripheral region and/or both peripheral regions comprise an elastomeric material.

5. The belt according to claim 1 , wherein the belt is a round baler belt.

6. A round baler belt comprising an internal region, an external region, a core region arranged between the internal region and the external region, and two peripheral regions located opposite one another and arranged transversely to longitudinal direction of the round baler belt, wherein the peripheral region is arranged partially between the internal region and the external region, wherein the round baler belt is continuously closed in the longitudinal direction, and wherein core region is continuously wound without interruption in the longitudinal direction.

7. The round baler belt according to claim 6 , wherein the core region comprises a reinforcing fabric.

8. The round baler belt according to claim 6 , wherein the internal region and/or the external region and/or a peripheral region and/or both peripheral regions comprise an elastomeric material.

9. A method for producing a plurality of belts which are continuously closed in a longitudinal direction, the method comprising:
producing a plurality of continuously closed core regions;
arranging an internal region against the plurality of continuously closed core regions from the inside, the internal region protruding beyond the plurality of continuously closed core regions transversely to the longitudinal direction;
arranging peripheral regions laterally adjacent the plurality of continuously closed core regions transversely to the longitudinal direction;
arranging an external region on the plurality of continuously closed core regions from the outside, the external region protruding beyond the plurality of continuously closed core regions transversely to the longitudinal direction; and,
cutting at least one peripheral region in the longitudinal direction X to provide a plurality of belts;

wherein the peripheral regions are arranged partially between the internal region and the external region.

10. The method according to claim 9 further comprising vulcanizing the plurality of belts.

11. The method according to claim 9 further comprising separating at least one peripheral region and/or the internal region and/or the external region in the direction of the thickness (Z) of the belt, such that the at least one peripheral region terminates flush with the internal region and/or with the external region transversely to the longitudinal direction.

12. The method according to claim 9 , wherein the peripheral regions are three peripheral regions located adjacent one another transversely to the longitudinal direction.

13. The method according to claim 9 , wherein the plurality of continuously closed core regions are continuously wound without interruption in the longitudinal direction.

14. The method according to claim 9 , wherein the plurality of continuously closed core regions comprise a reinforcing fabric.

15. The method according to claim 9 , wherein the internal region and/or the external region and/or a peripheral region and/or the peripheral regions comprise an elastomeric material.

16. The method according to claim 9 , wherein the plurality of belts are round baler belts.
