ABSTRACT:
A quenching system for extrudates e.g. extruded laces consists of an inclined open ended trough along which water flows at a rate greater than the rate of extrusion to the laces. The laces may be fed to a lace-cutter either before or after being dried. The system may be arranged as a self-threading system.
