A belt band conveyor has an endless conveyor belt band guided over deflection and/or drive friction rollers, for deflecting and/or driving the conveyor belt band. Each roller includes an axially-extending shaft. At least three roller segments are releasably mounted on the shaft, axially apart from one another, so as to rotate about a rotational axis extending axially in the longitudinal direction, Each roller segment has an inside circumference contour and a friction surface on its radial outside circumference engaging on the lower belt with friction fit. The inside circumference contour of each roller segment and the outside circumference contour of the shaft are structured so that each roller segment is connected with the shaft with shape fit to prevent twisting about the rotational axis. When the shaft turns about the rotational axis, in a rotational direction, the roller segments also turn about the rotational axis, in this rotational direction. |

1. A belt band conveyor comprising:
(a) an endless conveyor belt band comprising a lower belt, (b) a plurality of friction rollers selected from the group consisting of deflection friction rollers for deflecting the conveyor belt band and drive friction rollers for driving the conveyor belt band, wherein the friction rollers are guided over the lower belt; and (c) a shaft extending in a longitudinal direction and having an outside circumference contour; wherein each friction roller comprises at least three roller segments mounted on the shaft in axially releasable manner and disposed axially adjacent at an axial distance from one another in the longitudinal direction; wherein each roller segment has an inside circumference contour and is mounted so as to rotate about an axis of rotation that extends axially in the longitudinal direction; wherein each roller segment has a respective friction surface on a radial outside circumference of the roller segment; wherein each roller segment engages on the lower belt of the conveyor belt band exclusively with friction fit by way of the respective friction surface; and wherein the inside circumference contour of each roller segment and the outside circumference contour of the shaft are structured to be coordinated with one another so that each roller segment is connected with the shaft with shape fit to prevent twisting about the axis of rotation so that when the shaft turns about the axis of rotation in a direction of rotation, the roller segments also turn about the axis of rotation in the direction of rotation; and wherein multiple support disks are set on in axially releasable manner for lateral support of each roller segment, wherein each support disk of the support disks extends away from the shaft, transverse or perpendicular to the axis of rotation, and wherein each roller segment of the roller segments is delimited by a first axial side surface and by a second axial side surface that faces axially away from the first axial side surface in the longitudinal direction, and wherein a first support disk of the support disks, in each instance, lies against the respective first axial side surface of the respective roller segment, and a second support disk of the support disks, in each instance, lies against the respective second axial side surface of the respective roller segment. |
