ABSTRACT:
The invention relates to a device and method for melt spinning and cooling a filament bundle. To this end, the device comprises a spinning device with an annular spinneret for extruding the filament bundle as well as a cooling unit arranged below the spinning device. The cooling unit comprises a holding device and a coolant dispersing head that is connected to said holding device. In an operating position, said coolant dispersing head is substantially centered relative to the spinneret with contact between the spinning device and the holding device. The coolant dispersing head can be guided into a standby position at a distance from the spinneret. According to the invention, a movable shielding means is arranged laterally of the coolant dispersing head and can be moved between an initial position laterally of the coolant dispersing head and a shielding position directly underneath the spinneret.
