This invention relates to a process for carrying out continuous demonomerization and postpolymerization of Polyamide 6 melts and a reactor for carrying out this process. The reactor of this invention has a cylinder with a horizontal axis around which an interior rotor shaped like a cage rotates. The reactor can be partially filled with polymer melt. There is a multitude of elements along the periphery of the rotor which partly dip into the melt and serve to convey the melt through the reactor, generate new surfaces and mix and homogenize the melt as the polymer melt undergoes demonomerization and postpolymerization under vacuum.

A device for spinning endless filaments out of synthetic polymers is disclosed. The device comprises a plurality of spin positions with each spin position having a spin head with four spinneret holders each fed by a multiple spin pump of a blowing chamber, a spin finish device and a winding device with at least two winding axes. The device is characterized in that one spinneret is in each spinneret holder and the spinneret can be fed by a spin pump with at least dosed melt streams, the quantity of which is designed for spinning four, eight or twelve ends per spin position which are adapted to be wound up thereafter.
