49003 Slitter machine
The slitter line is a line designed and expressly dedicated to the production of strips in rolls of various widths, that are prepared in rolls and then sent to the production lines. The first process involves loading the roll on a cradle and then its loading on the decoiler placed at the beginning of the line. The operator cuts the steel straps and feeds this strip into the introducer. From this point, the operation proceeds semi-automatically: the strip goes into the heading unit then to the shear with circular blades which divides the coil in smaller strips of the desired width. Continuing in semiautomatic mode, the strips go to the the felt-press with latch and get attached to the recoiler. From this point, processing can continue automatically until the strip on the first decoiler is finished. The strips are placed on an unloading cradle, closed with steel strap and sent the the production lines.

Machine configuration
Base in sheet structure and steelwork, where are the bearings that carry the mandrel. Mandrel in steel Aq 55 mounted in overhang on high-tight bearings fitted with protection for grease tightness. The drum with 3-4 tiles in aluminum or mild steel mounted on conrods or inclined planes.
Automatic tiles opening with hydraulic cylinder that lies in the back part of the mandrel and connected to the drum with bar that passes in the mandrel. Fitted with hydraulic power pack (the un-coilers with hydraulic opening)
Pneumatic or electro-magnetic (in case of motorized un-coiler) brake (or brake lining for the smallest un-coilers).
Motorization with inverter forwards-backwards in the base
Paint: Blue Ral 5015.
Line direction: reversible
Electric panel on board
Loop control with arm (if motorized) or with photocell
Compressed air pressure 6 bar
Air consumption 10 NL/min.
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.
The motorised coil-pressing device is generally installed on top of the decoiler. This hydraulic unit is made up of a mobile metal arm and of a wheel (toothed or rubberized) to push the sheet. Its function is as simple as essential. Its final aim is to insert the new strip in the straightener or directly in the roll forming line and restart the new working session. The operations are managed and controlled by the operator at a distance with manual commands, therefore avoiding risks of involuntary accidents.
Machinery for compressing the metal scraps produced by the slitter line.
A complete reel winder with rewinding in the opposite direction (with respect to unwinding).
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
