Abstract

A spinning manifold for melt-spinning synthetic high polymers is disclosed. The manifold has an elongated hollow body with cavities for the conduction of a heating medium, such as diphenyl, and a vertical nozzle shaft having heatable members placed between serially arranged and dismountable nozzle blocks such that the side walls of the heatable members are in heat exchange with adjacent nozzle blocks. These heatable members are displaceably mounted within the nozzle shaft. The pump shaft of the spinning manifold may also have additional heatable members placed between the pumping units. The same heating medium that flows through the cavities of the spinning manifold is placed within the heatable members.
