COE type

Mono bladder tree with shells

A shaft for sensitive products (winding with or without core)

Designed for winding and unwinding rolls of varying widths, these shafts are particularly suitable for winding applications where expanded length is an important factor. They allow the use of one or more coils on the same shaft. They can be made as a half pin for cantilever applications. The “COE” model is recommended for the winding/unwinding of sensitive or fragile products which do not accept the deformation of their mandrels. In the "COE" pinch version, winding without core on materials with a thickness of a few tenths of a millimeter to several millimeters is possible. These shafts are made of steel, aluminum or composite. Depending on the application, they are equipped with smooth, ribbed or vulcanized shells. The custom design and manufacture of the shafts allows the perfect match with your needs and in particular your torque, load and speed constraints. Possibility of “Great Expansion” trees. The range of COE type expandable shafts allows the use of chucks with diameters from 40 to 250mm.
