Planet Series Angle Rolls
The Parmigiani PLANET Series represents the pinnacle of angle and section bending technology — machines engineered to cold roll virtually any standard structural shape on the market, including angles, beams, channels, flat bars, square and round tubing, and pipes. Built on a rigid monoblock frame with three fully driven rolls and Parmigiani's exclusive HTT hydraulic torque management system, the PLANET Series delivers unmatched power, precision, and throughput across a full lineup of models — from the compact PLANET 15 up to the heavy-industry PLANET 250.
Designed and manufactured entirely in Cremona, Italy since 1927, every PLANET machine reflects nearly a century of forming expertise. These machines are the choice of fabricators who demand consistent results, minimal setup time, and long-term reliability — backed by an ISO 9001:2015 certified quality system and the full support of Carell Industrial Solutions, Exclusive U.S. distributor.
Technical Details
HTT Drive System — Three Powered Rolls
Every PLANET machine is driven by three independent hydraulic motors — one for each roll — interconnected through Parmigiani's exclusive HTT (Hydraulic Torque Transfer) system. Rather than relying on a single drive source distributed across rolls, the HTT system automatically compensates for differences in peripheral speed between rolls based on the profile size and bending radius in real time. The result is optimal torque distribution across all three rolls throughout the entire bending cycle, regardless of section shape or material.
Each hydraulic motor couples directly to its driven roll through a planetary gear transmission, delivering higher driving torque than competing machines while ensuring smooth, consistent material feed. This combination of independent drive and intelligent synchronization means fewer bending passes, less operator intervention, and better finished geometry — even on challenging profiles like thick-walled pipe, large structural angles, and hard-way beam bending.
