摘要： The invention relates to an extrusion head (10) for a blow molding machine for producing two-layer synthetic hollow bodies. Said blow molding machine comprises one or more extruders for feeding molten synthetic material which extruders are connected to the housing (12) of the extrusion head. The aim of the invention is to make sure that, if different synthetic materials of different viscosities are used, both materials have substantially the same rheological flow conditions when they are distributed across the circumference of the die to form a tubular preform. To this end, the expulsion piston consist of two concentric cylinder bushes (16, 18) which define between them an annular gap in which the two distributor organs are located on opposite sides inside on the inner surface of the outer cylinder bush and outside on the outer surface of the inner cylinder bush. The synthetic materials of the two distributor organs that are distributed across the circumference are issued by the expulsion piston (16, 18) into the cavity (22) of the extrusion head (10) approximately in the center of the expulsion piston at the lower end of the annular gap.

摘要： The invention relates to a method and a device for the production of blow-molded two- or multi-layer containers made of thermoplastic, and a plastic container produced accordingly, having view strips, particularly for storage and for transport of liquid bulk material. To this end, molten plastic material is deflected in an extrusion head (10) from the inner, natural-colored layer (34) of the tubular premold (18) into the outer layer (36) in a process technical step, and embedded there, whereby a view strip (24) is formed in the exterior, dyed plastic layer (36).

摘要： The invention relates to a method and device for cleaning extrusion heads (10) in the extrusion of thermoplastics, which are ejected or extruded from an extrusion nozzle (14) as a tubular preform (12). According to the invention, in order to remove interfering deposits and baked-on residues (20) on the outlet nozzle (14), the tubular preform (12) is briefly turned around and upset, wherein the deposits (20) adhering in the vicinity of the outlet nozzle (14) are wiped off and transported away by the tubular preform (12). In an advantageous way, the tubular preform (12) itself is used as a cleaning element while the tubular preform is being turned around, while the cleaning automatically occurs during the ongoing operation of the continuous extrusion without interruption of the production process.
