ABSTRACT:
The yarn entry and exit openings in a container for high pressure gaseous or liquid yarn heating medium are each sealed by means of a plunger mounted to slide in a cylinder extending from the opening. Each plunger is formed with a longitudinal groove of U-shaped cross-section on its surface. Therefore, to thread the yarn, it is only necessary to withdraw the plungers from their cylinders, place the yarn in the grooves and replace the plungers. Substantially to eliminate the escape of medium along the grooves, each may have a depth substantially equal to its width and amounting to between 0.1 mm and 0.5 mm, according to the yarn. However, to accommodate yarn with knots along its length or strechable yarn, this dimension may be increased and the pressure of any escaping medium reduced in a stepwise manner by recesses distributed along the plunger and intersecting the groove, into which recesses any escaping medium can expand.
