ABSTRACT:
A fabric sample is stretched between two grippers mounted on two moveable parts, one of which slides on the other. A pair of plier-like hand grips exerts a force through a coil spring on the two moveable parts so that the displacement of the two parts relative to each other measures the amount of stretch of the fabric sample whereas the amount of compression of the spring indicates the force being applied to achieve that amount of stretching.
