Abstract

An apparatus for automatically testing the breaking strength of textiles during the spinning process is disclosed. A yarn clamping means affixed to a breaking assembly is rotatably mounted to an automatic timer which is pre-programmed to break yarn at set intervals. The spinning yarn is passed through a tension sensing device which measures the strength of the yarn at the breaking point, after the clamping means rotates, catches, and breaks the yarn. The clamping means then rotates back to the original position and restores and recombines the yarn as new feed yarn.
