Extruder head for the manufacturing of semi-finished products from thermoplastic materials.

摘要

The head has a flow channel (3), which can be divided into at least two individual channels (9, 10) in a dividing region by a torpedo (8) arranged in the axial direction. The individual channels can be brought together again immediately ahead of the flow channel mouth (6). The torpedo has a plurality of directing devices (14) and (15), which are aligned essentially parallel to one another or radially in the direction of a common point of intersection as well as in each case at an angle with respect to the direction of flow in the flow channel, preferably at an angle of about 45 DEG . <IMAGE>
