Abstract

PURPOSE:To measure tension of the membrane surface near the point of application of force easily and accurately by applying an approximately constant vertical force at a prescribed position on the membrane surface and measuring the depth of sinking at the point of application of force, with the membrane surface apart a prescribed range from the point of application of force as a reference. CONSTITUTION:A measuring device 10 comprises an annular base 11 that forms a concave part 11a having constant width and depth in the lower side surface in the center, a support 12 planted vertically in the upper direction from the upper surface near the outer peripheral part of the base 11, a dial gage 13 mounted on the upper end of the same support 12 and a detecting rod 14 provided on said gage 13. And when the annular base 11 is placed near the outer peripheral part of a leather 5 adjacent to a tension rod 7 of a drum, the depth of sinking of the detecting rod 14 can be obtained. In the instance, since the depth of sinking at the tip of the detecting rod 14 is measured with the dial gage 13, the degree of tension of the leather 5 can be determined easily and precisely.
