Abstract
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.
