Abstract
A spin pot, for the extrusion of one or more ends of multifilament, synthetic fibers, which essentially eliminates all stagnant zones caused by nonuniform flow patterns while yielding yarns of high quality at high extrusion rates for an extended period between spin pot changes. 'Plug flow' is achieved throughout the passage of polymer through the spin pot by the design of the internal parts wherein: the optimum number and location of polymer delivery channels in the top cap are defined, polymer flow throughout the spin pot is streamlined, and improved sealing characteristics are provided by the design of the top cap and the breaker plate.
