Abstract
An apparatus for quenching synthetic filaments which comprises an elongated chimney, a porous open-celled foam sheet, dividing said chimney longitudinally into a plenum chamber and a quenching chamber through which filaments pass in a path from an extrusion device to a means for collecting filaments and a means to supply a flow of gas to the plenum chamber. The improvement comprises a mesh screen coextensive with the foam sheet positioned between the foam sheet and the quenching chamber.
