摘要：
An apparatus is described having an extrusion means for extruding a molten polymer strand; a pelletizer; and a trough disposed to convey a polymer strand from the extrusion means to the pelletizer; the trough has an interior bottom surface; a water dispensing means disposed to provide a layer of water on a first portion of the interior bottom surface that is proximate to the extrusion means; a mesh or perforated surface disposed in the trough downstream from the water dispensing means, disposed to permit the separation of water from a water-immersed strand incident upon it; and a second portion of the interior bottom surface downstream from that mesh or perforated surface, disposed to contain a layer of water.
