Disclosed is an extrusion device, with a die part, supported on a stationary part, having feed passageways for the plastic material on the inlet side and shaping slots, communicating with the feed passageways, on the outlet side. The die passageway for the skin of the honeycomb structure is formed by interaction of an adjustable die element with the die part on the outlet side. In the feeds of the die passageway are arranged adjustable means for regulating the flow rate of the plastic material.

Extrusion device for the production of honeycomb structures

In the case of this extrusion device, a die part with feed passageways for the plastic material on the inlet side and shaping slots on the outlet side, which are connected to the feed passageways, is supported on a stationary part. The die passageway for the skin of the honeycomb structure is formed by interaction of an adjustable die element with the die part on the outlet side. For this purpose, a disk spring column as die element is arranged around the die part and is supported on a tensioning element which is adjustable in the flow direction of the material. In the feeds of the die passageway is arranged an adjustable means for regulating the flow rate of the plastic material.
