ABSTRACT:
The invention is concerned with a system for monitoring the feed rate of a cut strip which is to be applied to a rotating tube for use in the production of fin tubing and includes a dancing roll to monitor the feed rate of the strip in response to the tension applied by the strip to the dancing roll as it is fed from a direct hydraulic drive during application to the rotating tube, the tension in the strip being maintained essentially constant throughout.
