A method and device for controlling the feed of an elastomeric yarn ( 11 ), of known elastic characteristics, withdrawn from a bobbin (B) and fed to a textile machine ( 10 ) such as a knitting machine, a stocking machine, a bobbin winder or other textile machine, the yarn possessing an intrinsic elasticity and being fed to the machine with an intrinsic speed, there being provided elements ( 18 ) for sensing the tension of the yarn ( 11 ) and elements ( 3, 12 ) for measuring and modifying this speed, both associated with a single body ( 2 ) of the device ( 1 ) and both connected to elements ( 20 ) for controlling and regulating the tension and speed parameters; elements for compensating the variation in the elongation of the yarn being provided to maintain the diameter and the quantity of the yarn fed to the textile machine constant.
