An apparatus providing a hot section in a continuously moving synthetic yarn wherein at least one jet of hot fluid obliquely is directly across the moving yarn. The jet intersects the yarn at an obtuse angle to the approaching yarn. The apparatus also produces drawn yarn by passing undrawn yarn into the jet and tensioning the yarn as it passes through the jet. The apparatus includes a body member formed with a chamber formed with yarn entry and exit passages and a fluid ejecting nozzle. The body member may be additionally formed with a cavity opening from the chamber opposite the nozzle.
