| 摘要 |
The invention relates to a device for guiding and/or shaping a plastic strand and/or a plastic profile, preferably a plastic tube, comprising an area (8) having a variable cross-section (9), and means for varying the variable cross-section (9), wherein the area (8) having the variable cross-section (9) is formed of flat stock, wherein the flat stock overlaps in partial areas and wherein the flat material rests closely against each other in the overlapping area. According to the invention, a plurality of segment-shaped flat materials (5a) form the area (8) having the variable cross-section (9), wherein each of the segment-shaped flat material has an integrally molded bend, and wherein the integrally molded bends (6a) of the plurality of segment-shaped flat materials (5a) form the draw-in area (6) of the device, wherein the draw-in area (6) is widened with respect to the cross-section (9). |
