ABSTRACT:
A short span tensile tester for testing a sheet such as a paper web is provided with two pairs of clamping jaws mounted in adjacent clamping relation, to clamp a portion of sheet material therebetween, one pair of jaws being pivotably mounted to swing under gravity into contacting relation with the other pair of jaws, to define a minimal span of up to about 3 m.m. A wedging device forces displacement of the jaws in the plane of the web to rupture the web, and force measuring means measure the wedge reaction force and hence the web rupture strength.
