Abstract
A process and a device involves melt-spinning and cooling synthetic filaments. Therein, a plurality of filaments is extruded from a polymer melt and, after the extrusion, is guided into a cooling shaft for cooling. Within the cooling shaft cool air is blown, via a blower wall, into the cooling shaft, where, for cooling, the filaments are guided along the blower wall and at a distance from it. In order to obtain cooling adapted to the particular filament titer, the blowing onto the filaments can be set by selecting one of several operating positions, where to change the operating position of the blower wall it is moved in the direction towards the filaments or in the direction away from the filaments.
