    • A melt-spinning apparatus usable for producing various synthetic fibers in various manners includes a polymer melter (6); a heat-insulating housing (1) having a detachable ceiling cover (14a) and a bottom (14b) having an opening (5); a detachable beam block (10) having a cavity (38) formed between a pair of longitudinal side walls (47, 48), one of which has a polymer melt outlet (20); a melt-spinning pack (16) arranged below the beam block (10) and having a head projection (51) inserted into the cavity (38), the head projection (51) having a polymer melt inlet (42); a polymer melt passage system (7, 13; 18; 19) extending from the polymer melter (6) to the polymer melt outlet (20); a fixing means for fixing the melt-spinning pack (16) detachably to the beam block (10) including a pushing member (24) for pushing the head projection (51) of the melt-spinning pack (16) toward the longitudinal side wall (47) having the polymer melt outlet (20) to cause the polymer melt inlet (42) to be fluid tightly connected to the polymer melt outlet (20), and optionally, means (39,22,40,43 etc) for protecting the polymer melt inlet (42) from damage when the melt-spinning pack (16) is inserted into the cavity (38) of the beam block (10).
