Abstract

The invention relates to an extrusion line for producing plastic profiles, preferably plastic tubes, comprising at least one extruder (1), a tool (2), a calibrator (3) and additional post-processing devices (4, 5). According to the invention, at least the tool (2) has at least one passage (8), and a suction device (6) is arranged upstream of the tool (2) when seen in the direction of extrusion (7), said tool (2) having several functional areas with separate melt channels. The invention also relates to a method for increasing the cooling power of the extrusion line.
