The support roller arrangements each include a first group having support rollers and at least one support roller offset relative thereto in the conveying direction and peripheral direction. A distance determined along the conveying direction between the first group of support rollers and the at least one support roller of the same support roller arrangement offset relative thereto measures between 15% and 85% of a distance between the first group of the support roller arrangement and the first group of the next support roller arrangement in the conveying direction. ## Claims ### Claim at position 1 1-8. (canceled) ### Claim 9 A conveyor belt system, comprising: a conveyor belt extending in a conveying direction and having an outer periphery defining a peripheral direction; and support roller arrangements spaced apart from each other along said conveyor belt, each respective one of said support roller arrangements having six support rollers distributed annularly around said outer periphery of said conveyor belt and shaping said conveyor belt into a tube; said support roller arrangements each having a first group of support rollers and at least one support roller offset relative to said support rollers of said first group in said conveying direction and said peripheral direction; said first group of support rollers of one of said support roller arrangements being spaced apart from said first group of support rollers of a next one of said support roller arrangements by a first group to first group distance in said conveying direction; and within one of said support roller arrangements, said first group of support rollers and said at least one support roller offset relative to said support rollers of said first group, being spaced apart by a support roller to support roller distance determined along said conveying direction measuring between 15% and 85% of said first group to first group distance. ### Claim 10 (depends on 9) The conveyor belt system according to claim 9, wherein said support roller to support roller distance measures between 20% and 80% of said first group to first group distance. ### Claim 11 (depends on 9) The conveyor belt system according to claim 9, wherein said support roller to support roller distance measures between 25% and 75% of said first group to first group distance. ### Claim 12 (depends on 9) The conveyor belt system according to claim 9, wherein said at least one support roller being offset relative to said support rollers of said first group is positioned approximately centrally in said conveying direction between said first group of support rollers in said one support roller arrangement and said first group of support rollers in said next support roller arrangement. ### Claim 13 (depends on 9) The conveyor belt system according to claim 9, wherein said at least one support roller being offset relative to said support rollers of said first group, in said respective support roller arrangements, forms a second group of support rollers including at least one additional support roller being offset relative to said support rollers of said first group in said conveying direction and in said peripheral direction. ### Claim 14 (depends on 13) The conveyor belt system according to claim 13, wherein said first group and said second group each have three respective support rollers. ### Claim 15 (depends on 9) The conveyor belt system according to claim 9, which further comprises supporting devices being separated and spaced apart from each other, said first group of support rollers and said at least one support roller being offset relative to said support rollers of said first group each being situated on a respective one of said supporting devices in the same support roller arrangement. ### Claim 16 (depends on 9) The conveyor belt system according to claim 9, wherein said conveyor belt is composed of a flexible base material and traction devices embedded therein. ### Claim 17 (depends on 9) The conveyor belt system according to claim 9, wherein said support roller arrangements are located consecutively along a polygonal line running at least along a partial length of the system.
