Optimal designed manifold system ensures a same duration and same distance for polymer melt pumped to every spinning position. Polymer melt flow is measured by one VFD controlled single inlet/ outlet gear pump. Operation and maintenance is easy. Every spinning position can start or stop individually, the difficulty and cost for change over the spin packs reduces.
With a well-designed spin pack pressure detecting system, the moment for change over the spin pack is now no more rely on operators' experience only.
