Abstract
A thread brake includes a plurality of fixed thread guide elements, at least two movable thread guide elements mounted on a rotatable body which, through rotation, can be brought in opposite directions to cross a path of a thread being guided by the fixed thread guide elements and thereby engage the thread such that the thread is bent in two places, thereby braking the thread. Rotation of the movable thread guide elements may be restricted during braking by taps appropriately positioned.
