摘要
The invention relates to a method and a device for melt spinning and cooling a plurality of synthetic filaments. According to said method, the filaments are first extruded in an annular configuration by means of a spinneret (1) and are then guided along a blowing tube (12) and cooled by a radial air stream emerging from the jacket of the blowing tube. The invention is characterised in that the filaments are pre-cooled for setting purposes prior to being cooled by the jacket air stream, by means of an additional pre-cooling air stream (7), which is generated by a coolant (6) that is located between the spinneret (1) and the blowing tube (12).
