ABSTRACT:
A conveying device for transportation of extended line products such as cables or tubes has tension elements to exert a tension force on at least two tension chain wheels in the direction away from the driving chain wheels. A self-locking wedge prevents the tension chain wheels from moving back and forth. The automatic adjustment of the roller chains reduces wear of the conveying device and prevents speed changes during transportation of the extended line product.
