Cut-to-Length Line

The cut-to-length line is designed for sheet metal production by leveling and cutting a mother coil into cross sections, creating completely flat formats that are properly stacked.  The machine’s main components include uncoiler, leveler, feeder, shear, and stacker. Together, these elements work seamlessly to convert coils into flat sheets that meet precise length specifications. Our cut to length line is suitable for hot rolling carbon steel, cold rolling carbon steel, tin plate coils, stainless steel coils and other kind of metals with coated surface.

The process is consists of coil supplying，cutting, stacking, packing and releasing. At the beginning, the coil is placed on the uncoiler, where it is gradually unwound as it moves through the production line. As the strip passes through the pre – leveling and precisive leveling machine, removing any curvature or imperfections, the flattened sheet is fed forward to the shear unit.

Under the guide of pinching device, the strip runs through measuring rolls where the strip length is accurately measured, and then shearing is carried out and the sheet is cut to the desired length according to preset measurements.

After cutting, the sheets are neatly stacked and ready for further processing or transport.

SRET’s cut-to-length line is manufactured in consideration of automation, high quality, energy saving, productivity and stability, ensuring that each sheet produced meets specific length requirements, improving efficiency and reducing waste.

Value Highlights

• Strict control in the processingof all components, fabricated parts with stress relieved by annealing, shot blasting and machining by modern precise CNC center.
• Heavy-duty bearing, and coupling with advanced oiling lubrication system, avoiding the wear of the bearing from wrong lubricating maintenance or not in time of manual operation.
• High quality leveling by means of different types of precision levelers (4 and 6 high) and sizesof leveling rolls. All of them with high precision and very robust
• Optimal production performance, through a wide range of shears (hydraulic, flying, rotary and electronic) and multiple stacking solutions (turbo-blower system, bomb-door, combined, magnetic and vacuum).
