Zusammenfassung:A melt distributor (1) having a plurality of bifurcated melt passages melt passages (5.1, 5.2, 5.3) for redirecting and distributing melt flows from a thermoplastic plastic. The melt distributor can be connected to a multiple extrusion head for producing multi-layer preforms. The branched junction (8) is configured as a rounded y-shaped conduit branch, and at least the branched junction (8) between a supply passage part (6) and the discharging passage parts (7.1, 7.2) of the bifurcated melt passage follows a continuously bent curve, the curvature of which is not equal to zero. The rounded and continuously bent configuration of the branched junction (8) contributes to shorter flow paths and avoids the formation of dead zones.
