Abstract
An apparatus for measuring the tensile strength of a textile fabric comprises a measuring system having electromagnet, a mass capable of being held in place by the electromagnet, a piezoelectric force sensor connected to said mass, and a rounded-off impact body. By de-energizing the electromagnet, the impact body free-falls onto the textile fabric, which is held in place beneath the impact body under tension. The impact force detected by the sensor is converted to a form with which a computer can compute the tensile strength of the fabric. A series of measurements can be made of a length of fabric advanced through the apparatus in successive stages.
