ABSTRACT:
A device for melt extrusion spinning and cooling of a filament bundle comprises a spinning device with an annular spinning jet for extruding the filament bundle as well as a cooling device arranged below the spinning device. The cooling device comprises a holding device and a blowing chamber connected to the holding device. The blowing chamber is held in an operating position substantially centrally to the spinning jet in contact between the spinning device and the holding device. The blowing chamber can be axially displaced relative to the holding device between the operating position and a replacement position.
