Abstract
A thread treating nozzle includes two relatively movable parts (10) and (12) which may be brought into mutual contact to define a thread treating passage and which may be moved apart to permit insertion of the thread. The part (12) is an elastic plate (12) supported by a plate mounting structure (120) which includes a housing member (122) containing a pressurizable chamber (200) in which a bridge member (201) is guided freely for movement as a piston by guide walls (206). To prevent the pressure medium contained in the cylinder space from escaping via the clearance between the guide walls (206) and the bridge member (201) a seal (204) is provided. The bridge member (201) includes a base plate (202) contacting the bottom (208) of the seal (204), and bridge members (203) are fitted on plate (202) to bear against the plate (12). This permits exertion of a homogeneous pressure on the plate (12) as the chamber is pressurized, causing the plate (12) to deform and adapt to the sealing surface on the nozzle part (10) to establish a sealing contact between the two nozzle parts.
