ABSTRACT

The raw materials processed in textile possess poor physical and mechanical properties concerning tensile strength, homogeneity, and others. This causes frequent stops in the technological process due to thread breaks, engorgement, winding of the material around rollers and extra. Hand-labor is reduced by means of manipulators, robots, and automated machines. Local control units for data acquisition, processing, and retrieval, combined with intelligent field sensors, substantially increase the reliability of the automated system as a whole. The growing intensification of contemporary textile production resulted in the development of high-speed drawing frames for processing the textile slivers after the cards. The proposed closed-loop control system cannot influence short-length waves of irregularity within the textile sliver. The development of modern control system techniques also concerns such basic textile machines as the shuttleless looms. Modern looms make use of distributed DC and AC drive systems, synchronized by a central control unit.
