摘要: A tensioning unit (10) with automatic control of the tension (T) of yarn-formed fabrics (F), having a first electric card (50) mounted in an electromechanical cubicle (60) and used to set the drawing parameters or store and load applicational drawing programs, and a second electronic card (50A), identical to the first and mounted on the tensioning unit (10), and which utilizes a processing program to control an inverter (28), that is connected to a drawing motor (25), in response to a feedback signal originating from a linear position transducer (P) rigid with a spring (30) for tensioning the yarn; a third electronic card (40A) is provided to establish communication between the first electronic card (50) and the second (50A) via a serial line (54) using an infrared optical coupling system. The speed of the motor (25) is controlled on the basis of information received to the position of the spring (30), in such a manner as to maintain the yarn tension (T) constant.
