Abstract
In the conveying device (1) with pusher elements (2) every one of the pusher elements (2), respectively, comprises at least one roller element (3) and at least one spacer body (4), wherein the at least one spacer body (4) is designed for keeping pusher elements (2), which follow one another in the conveying device, at a distance from one another. In doing so, successive pusher elements (2) in conveying direction extend from a first end to a second end, and the pusher elements (2) in the zone of the first end are movably supported relative to a conveying track (7) by the at least one roller element (3). The pusher elements (2) in the zone of the second end are supported on an adjacent pusher element (2), and successive pusher elements (2) are loadable relative to one another only under compression, but not, however, under tension.
