Linear force measurement apparatus or device

摘要

A linear force measuring device for measuring the tension upon a web comprises a measuring ring built into the bearing assembly of a deflection roller over which the web passes. The measuring ring has a pair of slits cut into the ring, the slits having parallel rectilinear portions which are in a perpendicular direction of force application, further portions which extend to the periphery of the ring, and, at each extremity of the rectilinear portion, an inwardly turned portion extending at most 90 DEG .
