Cut-to-length lines
The standard production entails cutting lines manufactured for the following characteristics:
- Cutting width of 1000, 1250, 1500 and 1850 mm;
- Coil weight of 7 and 12 ton;
- Thickness of 0.2 mm to 1.2 mm (light-weight lines)
- Thickness of 0.4 mm to 2.5 mm of soft steel and 1.5 - 2 mm of stainless steel (heavy-duty lines).
The operational mode is the Start-Stop type with driver in direct current for cutting speeds of 30 m/min. and cutting tolerance of +/- mm 0.2.
The lines are available in two configurations:
LTB with straightener and compact crosswise
shears where the infeeder and the straightener trip the stoppage to make the crosswise cut. This typically called Start-Stop line is suitable for cutting normal materials such as galvanized, pickled, hot and cold laminated steel etc.
RTB with separate straightener and continuous infeed without stoppages, loop control for the infeed unit complete with crosswise
shears. This typically called Roll-Feeder line is more suitable for cutting materials such as stainless steel, aluminium and pre-painted metal, as the rollers of the straightener do not leave shaded marks on the surfaces.
The cutting lines can be made up of:
- Light-weight decoilers, with brake and stand support plus manual expansion spindle suitable for sheet metal cutting requirements;
- Heavy-duty decoilers with drive and overhenging spindle plus hydraulic expansion, equipped with hydraulic loading cradle;
- Straightening unit with 5, 7 and 11 rolls;
- Lengthwise cutting unit with circular blades, manual shifting system and rapid roll-blocking system. In alternative these may be built in the straighteners (LTB configuration) and in the feeders (RTB configuration);
- Mechanical guillotine type shears for the crosswise cut;
- Loading and stacking devices with lengths from 2000 mm to 6000 mm.
