Karl Mayer's EBA-1 yarn feed system is an electronic yarn draw-off mechanism for feeding warp sheets to the knitting elements of tricot and raschel machines. A wide control range eliminates adjustments to different yarn draw-off settings. The system operates with or without a sensing roll, depending on machine requirements. The system is notable for its yarn draw-off mechanism, which is a ball roll mechanism controlled by a computerized stepping motor. The stepping motor accurately and automatically positions the yarns draw-off mechanism, which is a ball roll mechanism controlled by a computerized stepping motor. The stepping motor accurately and automatically positions the yarn draw-off mechanism. Low maintenance and low noise toothed belts drive the system. The integration of a data interface permits the transmission of recorded data to an overlaid data acquisition and recording unit. This feature is for facilities which centralized production control. Data processing capabilities include informaion on the status of the macine, work-in-progressing, and individual shifts.
