摘要： 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.

摘要： A wearing body or bushing having an axial twin borehole for receiving a twin screw for extruding meltable material, in particular plastic. In order to avoid cracking and to save material, the wearing body has a radial cross section with an outer contour, which is convexly curved over the entire circumference and is in the form of an oval, and with first and second axes of symmetry, which run perpendicularly to one another and define a point of intersection which lies on the extrusion axis. The width of the oval on the first axis of symmetry is greater than the height of the oval on the second axis of symmetry.

摘要： An extruder screw includes an extruder shaft and at least one extruder segment. The extruder shaft has a prismatic mandrel having external teeth and a longitudinal mandrel axis. The extruder segment has internal teeth and a longitudinal internal-teeth axis and can be slid onto the mandrel, such that the extruder segment can be connected to the mandrel for rotation therewith. The internal teeth have a profile having a meshing profile and, in an inner area between the first and second end faces of the extruder segment, include a prismatic main profile that has a main cross-section. Furthermore, the internal teeth of the extruder segment have an edge profile adjacent to at least one end face of the extruder segment, which edge profile has a smaller edge cross-section than the main profile at least in the area of the meshing profile.

摘要： Apparatus for calendering continuously produced articles includes a at least one calender roll and a drive having a driveshaft which is constructed in the form of a cardan shaft and operatively connected to the at least one calender roll for rotating the at least one calender roll. In order to maintain the at least one calender roll at a desired temperature, a fluid passageway means is provided for circulation of a temperature control medium. The temperature control medium is hereby introduced into the driveshaft via a rotary hollow-shaft feedthrough which is constructed for distribution of the temperature control medium. The rotary hollow-shaft feedthrough has a first fluid passageway for providing a passageway to the driveshaft, and a second fluid passageway for providing a passageway for discharge of the temperature control medium.
