Abstract
A method of adjusting a given pretension in threads on tensile strength testing apparatus. A force measuring device is used as an adjusting member for the pretension, from where the tensile load increases and the elongation thereby appearing is measured. The loose thread inserted into the thread clamp is either pretensioned by means of a movable testing clamp, or the thread is stretched by a transport device until the force measuring device indicates the given pretension value.
