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

A device for melt extrusion spinning and cooling of a filament bundle comprises a spinning device with an annular spinning jet for extruding the filament bundle as well as a cooling device arranged below the spinning device. The cooling device comprises a holding device and a blowing chamber connected to the holding device. The blowing chamber is held in an operating position substantially centrally to the spinning jet in contact between the spinning device and the holding device. The blowing chamber can be axially displaced relative to the holding device between the operating position and a replacement position.

A machine for cutting staple fibers has a machine frame, a cutter holder supported rotatably relative to the machine frame and having an axis, a pressing member supported rotatably and having an axis of rotation which forms an obtuse angle with the axis of rotation of the cutter holder. The pressing member is coupled to the cutter holder. A drive drives the cutter holder and the pressing member. The machine has at least one synchronizing hinge having an inner hinge member and an outer hinge member for mounting the cutter holder and the pressing member.
