ABSTRACT:
A melt spinning apparatus is disclosed which is adapted for forming a plurality of synthetic filaments from a molten polymer. The apparatus comprises a spin block composed of a spin plate having a plurality of transverse ducts, a cover plate overlying the spin plate, and a cavity formed between the two plates and communicating with the ducts for receiving the molten polymer. A pair of side plates are disposed along respective opposite sides of the block, and the block and side plates include mating inclined contact surfaces whereby tightening of the side plates against the block causes the spin plate and cover plate to be pressed toward each other, whereby a seal is formed between the plates which prevents leakage of the molten plastic from the cavity.
