The De Iuliis regulators can be symmetrical or asymmetrical (to allow assembly of the doctor on the regulation roll), in stainless steel (fourdrinier machines or press section) or in carbon steel (dry ends). The latter can be of standard type (for temperatures ip to 110° C) and for high temperatures (up to 150°C).
For any piece of equipment it is possible to insert a mechanical misalignment device of the regulator roll which, by means of a screw-jack, also gives a measurement of the fixed roll misalignment.
The misalignment device can be installed separately, from the tender side, or integrated into the regulator, making up a whole piece; in the latter case it clearly offers an advantage to have the pneumatic actuator on the tender side, thereby simplifying maintenance.
The misalignment regulation can be manual or motorized and the measure of the misalignment can be visual or by remote control for the sections of the machine which are not easily accessible.
De Iuliis produces two different sizes for each type of regulator:
- for rolls width up to 3.5m
- for rolls width from 3.5m to 6m
