Flow distribution plates

摘要

Flow distribution plate sets form an element of a spin pack which has a spinneret for spinning synthetic fibers from one or more liquid polymer streams. The plate sets include at least one patterned plate and for each patterned plate, at least one boundary plate. The patterned plate has at least one flow distribution pattern stenciled therein by cutting through. The boundary plate is stacked sealingly adjacent to the pattern plate and has cut-through portions to form at least one flow-through channel to allow fluid flow through the patterned plate and solid portions where the patterned plate is cut through to accomplish fluid flow in a direction transverse to the flow in the flow-through channel. The liquid polymer streams flow as discrete streams through the flow distribution plate sets to the spinneret.
