Abstract
An extrusion head arrangement has a plurality of extrusion heads arranged next to one another along a transverse axis. Each extrusion head has a housing with at least one flow channel for forming a strand of extrudable plastic in the direction of a longitudinal axis. The housing has an outer housing part extending along the longitudinal axis with an outer circumferential surface. A longitudinal bore parallel to the longitudinal axis is arranged in the outer housing part. The outer circumferential surface of the outer housing part has an oval cross-section with a largest diameter and a smallest diameter. The extrusion heads are arranged next to each other with the smallest diameters parallel to the transverse axis. The longitudinal bores are each arranged on a diameter deviating from the smallest diameter.
