| description | Improved equipment and method for spinning filaments for nonwovens using an integral spinbank including one or more spinplates producing filament bundles separated by one or more central conduits for quench air. Embodiments include high velocity quench air driven into the central conduit or quench air blown or drawn in from outside the filaments into the central conduit. Means may also be provided for removal of undesired waxes and/or other condensates through a central exhaust removal using the central conduit. As quench air velocity is increased through the central conduit, the streams tend to improve total quench flow by deflecting opposing flows into a uniform stream. Other variations include division of quench air into flow zones that may be independently controlled and varying the angle of quench air flow and/or the spinplates to maintain separation distance between quench air and filament bundles. |
