Abstract
An apparatus for spinning melt-spun filament yarns including a spin beam is disclosed. A polymer melt fed to a spin beam is distributed within the spin beam to a plurality of spinning cans mounted on the spin beam. To reduce costs to the manufacturer for ensuring ease of disassembly of the spin beam, as well as to avoid the need for disassembling the spin beam and having a furnace on hand, the spin beam is provided with an integrated or removably attachable regenerative heater by which the melt-conducting components of the spin beam can be heated to a regeneration temperature of between about 450 to 550.degree. C. to pyrolytically remove the deposits.
