Abstract
Infinitely adjustable calibrating shell includes a central piece formed by strips or bands which are hingedly connected to each other and intersect like an extendable lattice that is formed into a shell. Preferably, the ends of the strips are movably connected to annular heads. The inner diameter of the central piece which is decisive for the calibrating process, can be modified by axially changing the distance between the annular heads, the cross section of the central piece having a circular shape in each axial position. The infinitely adjustable calibrating shell is suitable for continuous extruded plastic parts, in particular plastic pipes.
