Tensoscan Automatic Warp Tension Monitoring Device

The Tensoscan Automatic Warp Tension Monitoring Device is designed to monitor the warping tension of the individual filaments in a warp sheet. An electrically driven measuring carriage mounted on two yarn guide bars travels at constant speed across the full width of the warp. As it moves back and forth across the yarn sheet, the probe senses tension in each yarn. The measuring carriage is attached by cable to a control box that amplifies and analyzes the signals produced by the probe. If tension is above or below preset values, a lamp starts flashing and the carriage stops at the end in question. After the yarn in question is fixed, a reset button is pushed to resume scanning. It is also possible to integrate the threshold switch with the stopping arrangement of the warping machine so that when a problem is detected, the warping unit stops with the Tensoscan unit. The Tensoscan scans at a rate of 0.4 meters per minute. In order for both the high and low tension settings to work, the individual filaments must be separated by 1.4 mm. For just high tension readings, the filaments must be at least 0.7 mm apart. A high-speed recorder can be hooked up to the device so that uniformity across the warp can be charted and analyzed.
