Abstract:
1. A method for feeding a plurality of yarns to a textile machine ( 5 ) for manufacturing either single articles or a continuous fabric or article, said feeding being carried out with the yarns having a constant fed length, each yarn ( 2 ) unwinding from a spool ( 1 ) and cooperating with a usual feed device ( 4 ), arranged to maintain the tension of the corresponding yarn ( 2 ) at a predefined value, before being directed to the textile machine ( 5 ), there being provided at least one control unit ( 6 ) connected to all the feed devices ( 4 ) for controlling the yarn feed to said machine ( 5 ), the absorbed yarn length value to be maintained for each yarn ( 2 ) fed to the textile machine ( 5 ) being set to a predefined setpoint value, characterized by measuring the actual values of the yarn length fed by each feed device and effectively absorbed by said machine ( 5 ), comparing these predefined setpoint values with said measured actual values and acting on at least one of said feed devices ( 4 ) to modify the feed tension value of the corresponding yarn ( 2 ) whenever this comparison indicates a deformity between said predefined setpoint values and the actual measured values, said feed tension modification making the actual absorbed yarn length value equal to the predefined setpoint value.
