Spinning beam for producing melt-spun filaments
A spinning beam for producing melt-spun filaments, in which liquid plastics material is conveyed via an externally arranged extruder to at least one pump, which conveys the liquid plastics material to at least one spin pack having a spinneret, at least the pump and the spin pack being heated by a heat transfer medium which is heated in a boiler. The pump, the boiler and an opening for receiving a spin pack are arranged in a modular assembly, which can be installed and fixed singly, or in a plurality one behind the other, in a frame of the spinning beam.
1. A spinning beam for producing melt-spun filaments, comprising:
a frame;
at least one spin pack having a spinneret;
an externally arranged extruder to convey liquid plastics material;
at least one pump arranged to receive the liquid plastics material from the externally arranged extruder and to convey the liquid plastics material to the at least one spin pack;
at least one modular assembly installable and fixable singly, or in a plurality one behind the other, in the frame, wherein the at least one modular assembly includes a suspension comprising at least two cross-members;
a boiler to heat a heat transfer medium, wherein the at least one pump and the at least one spin pack are arranged to be heated by the heat transfer medium and wherein the at least one pump, the boiler and structure defining at least one opening for receiving the at least one spin pack, respectively, are arranged in the at least one modular assembly; and
at least one heat chamber, wherein the cross-members are connected to the at least one heat chamber to form a supporting frame in which the at least one opening is disposed for receiving the at least one spin pack, respectively.
2. The spinning beam according to claim 1 , wherein the frame includes a long side and the at least one pump is arranged horizontally and transversely, or perpendicularly, to the long side of the frame.
3. The spinning beam according to claim 1 , wherein the frame includes a long side and the boiler is arranged horizontally and transversely, or perpendicularly, to the long side of the frame.
4. The spinning beam according to claim 1 , further comprising at least one vertically arranged pipe having a flange connection to guide the liquid plastics material to the at least one pump.
5. A spinning beam arrangement including the spinning beam according to claim 1 , and further comprising a framework outside of the spinning beam and a drive including a drive shaft arranged on the framework to drive the at least one pump.
6. A spinning beam arrangement including the spinning beam according to claim 1 , wherein the modular assembly comprises a plurality of modular assemblies forming the spinning beam, and further comprising a vacuum station and a condenser connected by pipes to the boiler in each of the plurality of modular assemblies.
7. The spinning beam arrangement according to claim 6 , further comprising the pipes connecting the boilers to one another.
