| 摘要 |
A melt-spinning apparatus usable for producing various synthetic fibers in various manners, including a polymer melter; a heat-insulating housing having a detachable ceiling cover and a bottom having an opening; a detachable beam block having a cavity formed between a pair of longitudinal side walls, one of which has a polymer melt outlet; a melt-spinning pack arranged below the beam block and having a head projection inserted into the cavity, the head projection having a polymer melt inlet; a polymer melt passage system extending from the polymer melter to the polymer melt outlet; a fixing means for fixing the melt-spinning pack detachably to the beam block including a pushing member for pushing the head projection of the melt-spinning pack toward the longitudinal side wall having the polymer melt outlet to cause the polymer melt inlets to be fluidtightly connected to the polymer melt outlets, and optionally, means for protecting the polymer melt inlet from damage which the melt-spinning pack is inserted into the cavity of the beam block.
