Roll forming line for the productoion of tables for scaffolding with special seaming of the sides and reinforcement obtained directly from the profiles. This is an automatic line starting from strip with innovative solutions. The lateral seaming of the table with a roll system allows avoiding the welding point on galvanized material and therefore avoiding the rapid formation of rust/oxidation. Besides the reinforcement is obtained from the same sheet. For such a complicated solution with rolls we have foreseen a heading and welding bench with 1000 mm width. The innovative ribbing head with rolls is used to carry out the anti-skidding by rolls and not with the press, to work faster. At the end the seaming system of the heads (from loaders) with the table executed with TOX ® and automatic stacking make the line completely automated.

It is a motorized decoiler (or idle on request) with the capacity of 15 tons. Complete with hydraulic power pack and independent electric plant. Hydraulic unit for the spindle regulation, an electric plant for the automatic / manual mode and for the speed regulation. Complete with loop, arm for the loop control, and spokes to maintain the strip in the correct position.
Hydraulic loading cradle for coils. It is used to load automatically the coil on the decoiler. It has a vertical movement through a hydraulic cylinder and a transversal motion for the transport on the unwinding axis with a gear motor command. This model has a capacity of 10 tons.

| Useful width | 1000 mm |
|---|---|
| Working height | 1000 mm |
It is a straightener with a pneumatic feeder added. It is made up of a total of 9 rolls (2 feeders and 7 straighteners). The main function generally is to feed a punching press, to straighten and to take out tensions from the sheet before being punched. This model has a useful width up to 1000 mm.
Technical data
| Maximum width | 200 mm |

| Welding unit electrical absorption | 43 amp |
| Material | Fe, galvanized, pre-painted, inox |
| Material minimun thickness | 0,3 mm |
| Material maximum thickness | 1,5 mm |
| Shear | electric |
| Blocking vices | included |
The 3 mm thickness heading and welding group performs a first locking of the strip to be processed with the first vice, then cuts the entering strip and blocks it with the second vice, after facing heading operation by the operator. Now starts the automatic welding, after which the vices unlock and the line can continue in automatic mode. As an option, it is possible to have the welding unit with n° 1 couple of motorized exit rolls (pinch-roll) with pneumatic lifting of the upper roll, n° 2 couples of motorized rolls (1 in entry and 1 in exit), with pneumatic lifting of the upper roll, and it is also possible to have as an option n° 3 sheet accompanying rolls




It is a set of forming rolls, made of tempered and rectified steel to make the profile requested by the client. The series of rolls is characterized by high precision and durability. Their function is at the heart of the whole plant; for this reason PM follows with particular precision the whole development (the whole process of roll-making is executed internally).


It is in the final part of the line and carries out the flying cut to measure (the roll forming line does not stop). The movement is through a hydraulic unit and electric motor. It includes the final cutting die made especially for the requested profile to have an extremely precise shear without product deformation. This solution increases considerably the productivity.

Simple motorised transport belt. It has to transport the piece from one working zone to another. Made up of a welded metal structure, it is completed with the insertion of rotating belts that transport the piece. The movement is through an electric motor.

Final bench used for the unloading and for the stacking of the finished piece. This special unloading bench is used mainly for trapezoidal / undulated sheet. Its structure allows the unloading of one piece on top of the other in order to have a lot ready for packing.
The whole electric installation is intended here. Electric cabinet, cable channels, control desk and software for the management of the line parameters, all according to the highest standards of quality and efficiency.

L'impianto idraulico è necessario nelle operazioni di taglio e nelle unità idrauliche di punzonatura o scantonatura. È composto dalla centralina (di potenza tale da soddisfare tutte le lavorazioni), dai collegamenti meccanici (tubature e valvole) e dal software di controllo e gestione.
Series of wire mesh, infrared photocells and sensors for the protection of the operators. They are installed on the line to avoid any accident that could cause physical damages to the operators
