Abstract:
A method and system for feeding a thread (F) at a preset drawing to a textile machine (T) comprising a first feeder (5) which sends the thread to the textile machine (T) and a second feeder (6) arranged spaced from the first feeder and which sends such thread to the latter, each feeder (4, 5) having a rotary member (15) on which there is partly wound the thread (F) before the feeding thereof and speed sensor means adapted to detect the rotational speed of such rotary member and tension sensor means adapted to detect the tension of the thread (F) exiting from each feeder (4,5).

Abstract:
A method for regulating the combustible mixture such as air/gas, air/methane gas or the like fed to a burner, said method consisting of measuring a flame signal correlated with the composition of said mixture fed by feed members controlled by combustion control means arranged to regulate the combustion on the basis of the flame signal. During burner operation the mixture feed conditions are modified within a narrow time interval such as to obtain a flame signal variation; a ratio between values of this latter at the end and at the beginning of said interval is compared with a predetermined reference value; and, on the basis of the deviation of this ratio from said reference value, the flame set point is regulated, as consequently is the air or gas of the mixture if this is rendered necessary.
