Abstract: One problem with weighing conveyors is that the tension of the conveyor belt, needed to allow the belt to be driven, inadvertently reduces the degree of sagging of the belt caused by the mass of the product on the belt, which affects weighing accuracy, as this pre-tensioning of the belt inadvertently supports some of the weight of the product being transported, and this tension supported fraction of the weight cannot be sensed by the load cell supporting the middle section of the belt. In a preferred embodiment, a flexible transition area is formed in-between the outer edges of the belt and the middle, product transport area, wherein the transition area comprises openings that serve to weaken the belt locally, such that a pre-tensioning of the middle part of the conveyor belt is reduced; this allows the middle part of the conveyor belt to hang substantially slack even as the outer edges of the conveyor belt are driven.

Abstract: A drive has a drive unit, wherein the drive unit includes a central body, a drive means, and a driven means circulating around the central body. Conveyor means or objects to be conveyed are able to be conveyed in a driven section of the drive unit along a conveyor path by way of the driven means.

To this end, the driven means rolls on the central body via rollers of the roller body and thereby the roller body transmits radial pressure forces to the central body. The driven means is driven directly by the drive means. The roller body itself is not driven directly by the drive means, but rather it is moved along solely by the rolling of the driven means on the roller body.
