-Supporting structure made of welded steel, widely dimensioned
-Spindle shaft supported by double roller bearings
-The expansion and closing of the spindle is carried out by wedges with hydraulic movement.
1.1 Motorized lateral translation
-by wheels on floor rails for strip alignment and coil loading
1.2 Snub arm
Integrated in the upper part of the decoiler, moved by means of a hydraulic cylinder, it is sized to contain the materials during insertion. The wheels coated with polyurethane allow not to damage the surface of the material, the movement is activated by the control panel
1.3 Stationary loading cradle
Fixed supporting structure in electro-welded steel,
hydraulic lifting duly sized to allow
the centring of the coils of different diameters on the spindle.
V-shape saddle for coil centring covered in polyurethane to not
damage the strip
With opening head by means of motorized mechanical jacks for:
-strip beginning introduction and cleaning
-Motorized overlapping pinch rollers placed at the entrance with
hydraulic opening and closing of the upper drive rollers
-Motorized lower and upper straightening rollers
contained in a weighing monobloc
-Block adjustment of the upper straightening rollers through
motorized mechanical jacks with display of the quota on the touch panel
-All rollers can be disassembled individually for an accurate maintenance or for being replaced
-Box for distributing movement to the rollers by means of helical gears
in oil bath
-Automatic cardan lubrication with oil recovery tank
-Grease-lubricated roller bearings (long life) for the rollers
straightening and back-up rolls
2.1 Independent motorized strip guide (infeed and outfeed)
Positioned at the entrance, the rollers allow to keep the belt guided during the feeding of the material.
2.2 Hydraulic threading table for strip beginning
to help strip insertion coming from the coil. The upper deflector roller facilitates the containment of the material bending while the extension of the table facilitates the removal of the sheet of the different diameters of the coil.
Table is polyurethane coated to not damage the strip
2.3 Encoder wheel
Positioned at the exit, it checks the quota set in the recipe, stopping the system if it is not positioned.
The control has two operating modes that can be set to your choice and stored in the recipe, A) motor resolver B) metric wheel
2.4 electro-welded fixed Base-frame with motorized height
2.5 Loop control
By mass contact under decoiler spindle
2.6 Free space for spray lubrification device
Space for assembly spray lubrification device located before hydraulic shear.
- Hydraulic shear for strip cutting positioned immediately after the straightener
- Duly sized to cut the materials to be processed.
- Cutting blades with 4 cutting edges.

4.1 Standard interface with the press
The interface, both functional and safety, with the press is performed via PN-ProfiSafe.
The PN-PN coupler, supplied by us, will be installed in our electrical panel.
The only contact signals required are the following:
– Start feeder cam
– Pilot cam (if any)
– Auxiliary cam (if any)
4.2 Software characteristics:
