Belt With Incorporated Tension Indicator

To show the tension of an elastic drive belt its outer side or back is provided with visual signs which change their appearance in accordance with tension.

As visual signs one or several tiny cuts are provided transverse the length axis of the belt on its back. With no or normal tension those cuts are not visible. Upon higher tension the cuts open and grooves become visible. If color is provided on the bottom of these cuts, the visibility is enhanced as the color becomes visible upon opening of the cuts from the increased tension.

Other realizations of visual indicators consist of imprinted lines arranged parallel to each other and transverse the length axis of the belt. If two lines are attached very close together, they form one line on an untensioned belt and two discrete lines on a tensioned belt. Also, distinct figures could be imprinted on the back of a belt. Those figures change their shape, contour and coloring dependent on different belt tensions.
