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.
In a spinning apparatus for melt spinning synthetic filament yarns including a heating box having a vertically extending opening formed therein of rectilinear cross section and including internal walls, a spinning head inserted in said vertically extending opening and including external walls corresponding in cross section with said internal walls of said opening of said heating box and being disposed closely adjacent thereto, and so that a pair of opposing vertical walls are positioned adjacent each other on two opposite sides of said spinning head, said vertically extending opening being closed in the upper end portion above said spinning head, and including means for supporting said spinning head in said heater box, said supporting means including an internal contact surface extending along each internal and external wall of each of said pairs of opposing walls, with the internal contact surfaces being aligned to collectively define a channel therebetween, and a supporting and locking strip means positioned in each of said channels for maintaining said spinning head in position in said vertically extending opening and permitting easy removal therefrom in a downward direction.
