LTB - Start-stop
START-STOP STRAIGHTENING AND CTL LINES
Main specifications:
The LTB straightening and cut-to-length lines are characterized for the operation with "Start-stop" system with compact straightener and crosswise cut shear.
The straightener work as a feeder and performs the positioning and stop for the crosswise cutting.
Possibility of integration of the lengthwise cut unit with cyrcula knives (multi-blankng) for maximum versatility of use, optimization of the sizes and reduction of the scraps.
For this reason the "Start-Stop" cutting lines are suitables for ferrous / not delicate materials (galvanized, hot and cold rolled, etc.) and for use in roofing / cladding market, light metal structures, molding and / or stamping etc.
- Standard working widths of 1000, 1250, 1500 and 1850 mm
- Thicknesses range from 0.3 to 3 mm (2 mm with Uts / Yield 650/320 MPa).
- Coils weights from 3 to 25 ton
- Straightening unit with 4, 5, 6 and 10 rolls without backup rolls.
- Working speed up to 40 m/min and cutting tolerances of +/- 0.2 mm.
- Maximum versatility, reduced overall dimensions and installation without the need for foundations.
- Decoiling with double operation modes: loop control for thin materials and electronic braking control for thick materials.
- Single, double or multiple devices for the application of the protective film or paper.
- Straightening rolls with independent manual or automatic adjustment of the penetration.
- Possible integration of the slitting unit (for multi-blanking) with manual positioning of the circular knives; with possibility of knives replacement without removing the shatfs from the machine; with electronic display device for fast and accurate circular knives positioning.
- New in 2015, cross cutting with mechanical guillotine shears with electronic drive by brushless motor (without flywheel and pneumatic brake-clutch unit).
- High performance, high reliability and reduced maintenance costs through the use of AC servo motors installed directly on the main feed rollers, with gear lubricated.
- High customization possibilities with different solutions of stacking sheets designed according to the specific needs of the buyer.
- Electronic equipment and latest generation hardware and software, touch-screen HMI with remote-assistance for the quickest and effective trouble shooting.
- Security systems in compliance with the strictest European standards rules.
