Abstract
A thread brake for a double-thread twister comprises a housing defining a relatively narrow thread passage and having a relatively wide compartment defined by at least one of the housing walls. A braking element provided in the compartment normally lies in a braking portion against the wall at the passage and is displaceable laterally of the passage into a position clear of this passage. Thus a thread extending along the passage is normally pinched by the braking element against the wall. A threading element is also provided in the housing and has an elongated relatively narrow open course. This threading element is displaceable between a position with the course out of alignment with the thread passage in the compartment and into a threading position with the course aligned with the passage in the compartment. Operating means connected to an inlet tube forming part of the passage is displaceable for shifting the threading element from outside the housing into the threading position and for simultaneously displacing the braking element out of the braking position. Two such braking arrangements can be provided in the housing.
