Abstract (en)

[origin: EP0943713A2] The tension in the yarn (7) is measured by the force exerted on a guide peg (21). An actuator can move two further pegs (42,43) into the yarn path to lift the yarn off the measuring peg (21) to calibrate the zero position on the transducer. Independent claims are also included for the following: a) A yarn feeder for knitting machines with strongly variable yarn requirements, having a yarn delivery wheel (4) driven by a motor controlled by the claimed yarn tension sensor to provide constant feed tension. b) Analyzing the tension signal to detect periods when the tension can vary from the set value (e.g. during the carriage return on the knitting machine) and initiating the actuator to lift the yarn off the measuring peg, reset the zero and replace the yarn on the peg.
