    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.

    摘要： In a method for manufacturing and assembling a large size filament-reinforced plastic composite hollow body, such as a tank, an endless casing (1) made by filament winding is cut open in the axial direction, so that there are formed two ends (2, 3) in the casing. The open-cut casing (1) is rolled up in order to form a transport package (4) with a diameter that is essentially smaller than the diameter of a finished hollow body. The transport package (4) is transported to the assembly site. On the assembly site, the transport package (4) is set in an assembly stand (5), the outer dimensions of which are adjusted to correspond to the inside diameter of the finished hollow body. The casing (1) is unrolled around the assembly stand (5) to the size of the finished hollow body, so that the casing ends (2, 3) are matched end- on-end. The ends (2, 3) of the casing (1) are fastened by a tight-fitting seam for forming an endless casing. Finally other required elements are attached to the casing for obtaining a finished hollow body. The arrangement includes a filament winding device (9) for manufacturing the casing (1) for the hollow body. In addition, the arrangement includes a cutting device (12) for cutting the casing (1) open in the axial direction, a rolling device (13) for rolling up the casing (1) to form a transport package (4), and an assembly stand (5), which is arranged to receive inside it the transport package (4) for unrolling the casing (1) on the assembly stand (5).

    摘要： The invention relates to a method for producing a large-volume cup-shaped or tub-shaped container made of a synthetic thermoplastic material, whereby a compact plastic, flexible hose-type preform (6) is extruded to obtain a given length and the container (1) is subsequently shaped. In order to carry out said operations with the aid of extremely simple extrusion devices and moulds, the extruded preform (6) is expanded to a given size and a core (2) is moved upwards into the expanded preform (6). The lower, open end of the expanded preform (6) is then clamped against the core (2) to provide a seal and the preform is shaped by air in order to form a container.
