Abstract (en)
[origin: US4801257A] A melt spinning apparatus is disclosed wherein the spinning head is inserted in an upward manner from beneath into the lower end of a vertically extending opening in a heater box. Upwardly directed air currents are avoided in the vertically extending opening by providing a metallic contact, in the form of supporting and locking strips, between the heating box and the spinning head. The supporting and locking strips provide for the easy removal and insertion of the spinning head into and out of the heating box from beneath. The upper end of the spinning head is closed, and the internal walls of the vertically extending opening in the heater box and the external walls of adjacent spinning head are provided with internal contact surfaces which collectively define horizontal channels. The supporting and locking strips are positioned in the channels, and they include corresponding supporting surfaces engaging the contact surfaces of the spinning head and the heating box, for supporting the spinning head in the heating box, and for permitting easy removal of the spinning head from the heating box in a downward direction.
