ABSTRACT:
Infinitely adjustable calibration sleeve for extruded plastic pipes includes an inlet head and two strap layers that intersect like a lattice grate and that are linked with each other at the crossing points. In that manner, the inlet head and the strap layers are adjustable to the pipe diameter, and the inlet head has radially adjustable overlapping segments in a radial plane distributed over the perimeter of the plastic pipe to be calibrated, and the segments mesh and have slots in their overlapping areas. Further, the faces of the segments are configured to lie on the plastic pipe to be calibrated, and the strap layers are linked to the segments flush with the faces. Such a calibration sleeve effectively seals the vacuum tank from the environment and prevents deformations of the entering, extruded plastic pipe.
