ABSTRACT:
The tension of flexible material can be measured with improved accuracy with the tension measuring device and method of the present invention. The tension measuring device has an engaging means, a bending means, at least one displacement means, at least two sensing means, and one or more indicating means. The engaging means contacts the flexible linear material and in conjunction with the bending means provides a fixed angle of bending to the linear material. The one or more displacement means are associated with the engaging means and are displaced in response to the fixed bending angle of the linear material. The two or more sensing means are positioned to each other at any nonlinear angular relationship in sensing engagement with the displacement means. The sensing means initiate signals in response to the displacement of the displacing means. The signals are conveyed by the conducting means to the one or more indicating means which provides the output from the signals of the sensing means as conditioned, scaled of magnitudes for tension and coefficient of friction.
