ABSTRACT:
An apparatus for producing a substantially nonturbulent stream of cooling gas for quenching a melt extruded filament, said 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. Another feature of the apparatus is its ability to supply different gas rates to the upper and lower zones of the quench cabinet.
