Device for extruding hollow rods |
摘要 |
Claimed is an assembly to extrude thermoplastic pipes through a tool (3) and calibration unit (9) separated by a form chamber (20) with an outer form (24) that influences the diameter of a still pliable plastic pipe emerging from an annular gap (15) in the tool (3). The form chamber (20) incorporates a supplementary form insert (21). Inner and outer inserts (21, 24, 32) are located coaxially with the annular jet (15). The inserts are axially and radially adjustable relative to each other, thereby altering the pipe wall thickness. |
