Abstract
This invention relates to devices used for measuring tension in a moving web of material at a location adjacent to a coiling device. The invention consists of a single roller over which the web passes, the roller being supported by blocks at its end which incorporate flexure elements to provide the necessary constraints to motion of the blocks, and load cells are used to detect forces arising on the blocks. A signal of tension which is independent of wrap angle of the web around the roller is determined from a single load cell signal when the coil diameter is known, and is determined from two load cell signals when coil diameter is not known. Signals of wrap angle and coil diameter can also be obtained from the two load cell signals.
