Librastar
Cold rolling line Librastar is the perfect line to produce cold roll steel wire coils, smooth, ribbed or indented, to be used in products as reinforcing welded mesh, stirrups, cages and lattice girders for the civil and industrial construction, foundations and precast industry.
Cold rolling line Librastar combine the cold rolling process of the wire rod with the spooling of the cold rolled reinforced wire to the desired coil weight.
The shape and engineering details of the line allow to produce high-quality cold roll coils with excellent mechanical and geometrical properties of the ribbed profile. The final product can feed any type of welding reinforcing mesh machine or cut and bend equipment.

Highlights
- Descaler rolls can automatically and directly adjustable by receipt from control pulpit.
- Possibility to use 1, 2 or 3 rolling cassettes together (according to the requested reduction scale).
- Stress relieving device to improve mechanical characteristics (tensile strength, ductility, elongation) that can be installed in up or down position: while down, the pulling force is made by the bullblock and not by the spooler.
- Engineered for cold rolling and/or stretching process, with fast changing and settings.
- Horizontal bullblock, can be equipped with there (3) smooth capstans plusone (1) shape capstan for stretching that doesn’t require to be dismounted for production changing (drawn or stretched wire).
- Double locking clamp for wire (one at the exit of Librastar and one at the entry of the automatic spooler), so the wire is always kept tensioned even in case of break (to guarantee a good quality winding).
- Remote control assistance kit.
- Automatic greasing system for rolling cassettes, stretching panels and stress relieving rolls.
- Possibility to install a dust conveyor integrated system, using conveyors below the payoff and main units.
- Simple maintenance procedure and fast set-up of the machine.
- Smart design of the line in terms of layout dimensions.
- Customizable according to the customer needs.
