ABSTRACT:
A controllable and adjustable yarn tensioner having two rotationally driven brake plates, between which yarn to be placed in tension is guided, includes first and second rotationally supported shafts, one of the brake plates being disposed at one end of the first shaft, the other end of the first shaft having an operative connection with a driving device; the other of the brake plates being disposed at one end of the second shaft; both the first and the second shafts being in mutual alignment along a common rotary axis, the other end of the first shaft being also connected, via a transmission system disposed outside of the brake plates, to the other end of the second shaft; one of the two brake plates having a compression spring contributorily determining the braking force at which the brake plates are applied, whereby the braking force is adjustable by adjusting the length of the spring; the first shaft being axially slideable; and a brake plate-disengagement device connected to the first shaft.
