DEVICE FOR STRETCHING-OVER DRUMS AND ROLLERS OF CARDING MACHINE WITH ALL-METAL SAW-TOOTHED CARD CLOTHING Russian patent published in 2013 - IPC D01H9/00 

FIELD: textiles, paper.

SUBSTANCE: device for stretching-over drums and rollers of the carding machine with all-metal saw-toothed card clothing (AMSTCC) comprises a guide shaft rigidly mounted parallel to the sidewall of the stretched-over drum of the carding machine, a carriage mounted on the shaft with the ability to move along the drum sidewall, the lever with tension mechanism and with spreader of all-metal saw-toothed card clothing and a drive of the device for rotating the drum at a predetermined speed. The lever is mounted with its lower end to the carriage with the ability to move together with it while stretching-over the drum with the saw-toothed card clothing. On the lever, perpendicular to the drum axis a beam with a sensor and the receiver of the measuring device is fixed, located on opposite ends of the beam, at that the upper boundary of the scanning signal coming from the sensor to the receiver is located at least 1 mm above the measuring base, and its lower boundary is located at least 1 mm below the point of contact of the spreader with the sidewall of the drum. The beam with the sensor and the receiver is located at a distance of 0.1 to 400 mm from the spreader.

EFFECT: invention enables to combine the process of stretching-over with the process of quality control of the drum surface and to reduce 2 times the time of repair of the drum, to provide accuracy of the AMSTCC mounting, and to improve the quality of products produced and the reliability of operation of the carding machine.
