The TBH is a pyramid design plate roll with independent adjustment of the two lower rolls on inclined sliding guides. This allows to pre-bend and roll both plate edges with only one insertion (no need to remove and turn the plate). The three rolls drive assures the best plate feeding also when rolling thin plates and the large opening between the top and lower rolls increases machine flexibility.
The TBH bending machines are equipped with the exclusive Parmigiani Parallelism System (PPS) for rolls parallelism control (closed ring type).
The PPS assures the max precision in rolls positioning also after several years of intensive work.
Linear sliding guides with antifriction material (AVG System). (No maintenance; High loading and carrying capacity; Smooth and stable positioning).
All rolls, mounted on spherical roller bearings, are driven by separate hydraulic motor for each roll.
The TBH bending machines are equipped with the multibearing system that guarantees the highest reliability even for intensive productions and cone bending.
The TBH Series with capacities to 6” coupled with a selection of over 55 standard models provide unmatched flexibility and coverage of most any plate rolling requirement. Our 3 Roll as well as 4 Roll Plate Rolls can be designed and built to handle a wide range of specific rolling requirements to include shorter or longer lengths from 20 inches to 24 feet, custom roll cambers, slotted rolls for plate with flanges-lips-ribs, corrugated patterns for corrugated material, vertical rolling applications and more.
Lifetime precision
When you want to move to precision rolling look to Parmigiani
The PPS is the most advanced parallelism system today available on the market.
The rolls parallelism in a plate bending machine is the key factor for the production accuracy.
The capability to maintain the precision across the years is also another critical point.
For this reason, we employ the best of the today available technology: digital control system and hydraulic flow control via proportional valves. We have designed a system totally insensible at the wear that will give you years and years of trouble-free operation, keeping the machine positioning precision like the first day!
The top and bottoms rolls parallelism is fully controlled by a digital “high speed” FIELD BUS system.
The package includes also a set of hydraulic proportional valves with high performance digital control cards, matching the high speed of the FIELD BUS system.
This digital technology (the loop control is 20 times faster than PLC-based electronic controls) joined with the hydraulic proportional valves, provides a parallelism precision of about 0,1 mm.
