INVENTION: FILAMENT QUENCHING APPARATUS INVENTORS: DAVID PENDLEBURY and JAMES EDWIN BRADSHAW ABSTRACT OF THE DISCLOSURE An apparatus for producing a substantially nonturbulent stream of cooling gas for quenching a melt extruded filament, the apparatus comprising a new gas plenum chamber wherein gas diverting means turns and directs the cooling gas through the plenum chamber for passage through a diffuser, simultaneously reducing turbulence and smoothing the velocity profile of the cooling gas for passage through the diffuser. The plenum chamber is divided into at least two separate zones, to which different gas rates can be supplied, by first baffle means and second baffle means. The first baffle means extends from the diffuser to the gas diverting means, and the second baffle means extends from the intersection of the first baffle means and gas diverting means towards the gas entry opening to the plenum chamber. -1-
