Construction of thread treating nozzles

Abstract From the Canadian patent

A texturising nozzle for synthetic filaments is openable and closable to facilitate lacing up. The nozzle comprises a two-part carrier structure with the parts movable towards and away from each other to open and close the nozzle. The thread path through the nozzle is defined by means of insert elements releasably mounted on the carrier structure at least in that region of the path in which the main texturising step is performed. A thread infeed passage and a (preferably single) fluid infeed passage bring thread and treatment fluid together at a junction location and a guide, passage (which preferably widens in the downstream direction) leads the thread and fluid from the junction location …
