Abstract
A tyre strip extrusion apparatus includes extruders and an extrusion head which includes a head housing having feed openings respectively connected to the extruders for feed of extrusion material. An injection moulding tool is connected to the head housing and includes a profile plate formed with an outlet opening which communicates with the feed openings for extrusion material to flow from the feed openings to the outlet opening for extruding a web from the extrusion material. Bearing against the head housing along a first parting surface is a first distributor plate. A second distributor plate is arranged upstream of the profile plate in flow direction of the extrusion material. The first distributor plate bears along a second parting surface against the second distributor plate. The first and second distributor plates are configured such that at least a majority of the material paths runs through the first and second parting surfaces.
