Abstract
A measuring device measures the torsional rigidity of a motor vehicle weatherstrip of the type which tends to twist upon bending about its longitudinal axis as experienced during installation of the weatherstrip around a corner of a vehicle body opening. The measuring device includes a pair of a rotatably mounted arms carrying mounting shoes for gripping the weatherstrip at spaced apart points along the length of the weatherstrip. Pivot means mount the arms for movement to swing the mounting shoes in an arcuate path and thereby bend the weatherstrip about its longitudinal axis so that the weatherstrip tends to twist. An indicator clip is removably mounted on the weatherstrip intermediate the mounting shoes and twists with the twisting of the weatherstrip to indicate that the weatherstrip has experienced a predetermined degree of twisting during the arcuate bending of the weatherstrip. A readout gauge indicates the degree of bending which causes the weatherstrip to twist, thereby providing a measure of the torsional rigidity of the weatherstrip.
