Infinitely adjustable calibration sleeve for extruded plastic pipes

摘要

The infinitely adjustable calibrating shell (10) has an inlet head (12) and outlet head, whose axial distance is adjusted together. An inner strip (16) and outer strip intersect a folding grille in a cylindrical centerpiece (10.1) of the calibrating shell, and are flexibly connected together. The two sealings are spaced in direction of the outlet cone, and are arranged in an area of the inlet cone (10.2) or in a passage from inlet cone for centerpiece.
