The package of spinning nozzles is assembled of a nozzle plate, an intermediate plate and a cover plate. The upper side of the nozzle plate is provided with a plurality of parallel grooves each having a bottom wall formed with a series of spinning nozzles. The lower side of the intermediate plate is formed with a plurality of lamellae projecting into the corresponding grooves of the nozzle plate. Each lamella has a series of throughbores which are aligned with respective spinning nozzles. The intermediate plate is formed with a transverse main distributing channel which communicates at opposite sides thereof with distributing branch channels extending between the lamellae and being delimited by the upper side of the nozzle plate. The distributing branch channels communicate with respective spinning nozzles via curved recesses formed in the lateral walls of the grooves. The bottom side of the cover plate is formed with a dome-shaped recess enclosing the inlets of the through-bores in the intermediate plate. The recess is provided with an inlet for the core component of the extruded filaments and with another inlet for receiving a tubular conduit communicating with the transverse main distributing channel to supply the sheath component therein.

A synthetic granulate is fed into an extruder through an inclined upper part transiting into a short vertical lower part communicating with an inlet in the extruder. A down shaft of smaller diameter for feeding a stream of a dye stuff projects through the inclined part and terminates about midway in the vertical lower part. The stream of synthetic granulate forms below the outlet of the filling channel a funnel-shaped cavity onto which a stream of dosed dye stuff continuously falls. The interface of the cavity with the synthetic granules is continuously renewed and thus a uniform stream of the dye stuff is admixed to the granules.

An arrangement for melt spinning of synthetic high polymers comprising a spinning bar, rails arranged at a height of a nozzle set inserted in the spinning bar, and a device for exchanging the spinning bars and including a carriage with an arm hydraulically moveable from an inclined inwardly directed normal position to a horizontal working position, wherein a free end of the arm is connected with a table serving for receiving of the exchangeable nozzle set and provided with elements for centering and securing of the dismounted nozzle set.
