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.

Device for melt spinning and cooling a filament bundle

An apparatus for melt spinning and cooling a group of filaments comprising a spinning device with an annular spinneret and a cooling device arranged below the spinning device. The cooling device comprises a holder that is connected to a coolant dispersing head. The coolant dispersing head is centered relative to the spinneret with contact between the spinning device and the holder in an operating position. The coolant dispersing head can be guided into a standby position at a distance from the spinneret. A guide tube encloses the coolant dispersing head in the manner of a jacket with a clearance and which is open at its end facing toward the spinning device. The guide tube and coolant dispersing head are displaceable relative to one another in axial direction to produce an air stream at the blowing end of the guide tube during transition from the standby position to the operating position.
