FIELD: engines and pumps.
SUBSTANCE: invention is related to extruder nozzle for extrusion of hollow sections. Extruder nozzle comprises one or several cores. Extruder nozzle is provided with several flow channels for flows of melt, which have been already reduced into required section inside extruder nozzle. Extruder nozzle comprises several plates, at that in all plates with core or cores, excluding the last plate, flow channels are separated from each other, so that core or cores is or are connected with the remaining plate by means of links between flow channels. If flow channels in the last plate have through joint between each other, then core or cores of the last plate may be fastened to appropriate core or cores of the neighbouring plate. If flow channels in the last plate are connected between each other only on part of height, then core or cores of the last plate are connected to the remaining plate by means of these remaining links.
EFFECT: simpler coordination of flow front at the outlet from extruder nozzle and production of high quality section.
