<p>A device for the constant tension feeding of threads fed to a textile machine, said machine being apt to produce a manufactured product, said feeding taking place in a discontinuous way that is with phase sequences wherein the thread motion takes place with a first and a second feeding or absorption state, said states following each other in time, comprises tension detecting means (3), thread accumulating means (4) and control means (40) connected to said detecting means (3) and accumulators (4) and apt to intervene on the latter based upon a tension value obtained from said detecting means; compensating means (11) is provided arranged between said accumulating means (4) and said tension detecting means (3) apt to cooperate with such thread (8) so as to compensate a variation of the feeding or absorption state of the latter upon the passage between each first and each second feeding or absorption state following the first one.</p> |
