Versions of the RR Regulator series are designed to be used in all sections of the paper machine to control the sideways movement of wires and felts.
This equipment has been designed with the aim of optimizing the production process: each single regulator is studied and positioned to maximize the system efficiency.
There is a a complete range of machines to account for all the fundamental parameters.
The following points have been taken into consideration:

- the position of application in the paper machine
- the choice of the best material
- the width of the paper machine


De Iuliis regulators can be symmetrical or asymmetrical (to allow assembly of the doctor on the regulation roll), in stainless steel (for fourdrinier machines or press section) or in carbon steel (for the dry end). The latter can be of standard type (for temperatures up to 110° C) and for high temperatures (up to 150°C).
For any of the above 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 those sections of the machine which are not easily accessible.

De Iuliis produces two different sizes for each type of regulator:

- for rolls up to 3.5m wide
- for rolls from 3.5m to 6m wide
