High Speed Cut to Length Line
A High Speed Cut to Length Line (CTL) is an advanced coil processing system designed to continuously uncoil, level, measure, cut, and stack metal sheets at high production speeds. It converts steel coils into accurately cut sheets with consistent length, flatness, and surface quality.
LOTOSSLITTING designs and manufactures high speed CTL lines for applications requiring high productivity, precise sheet dimensions, and reliable automated operation.

FAQ :
Yes. A CTL line can normally be programmed to produce different sheet lengths within its designed operating range. The actual range depends on the machine specifications and control system.
Automation improves production consistency and reduces manual intervention. PLC control, servo feeding, automatic counting, flying shearing, and automatic stacking can improve productivity while maintaining stable processing accuracy.
The primary advantage is high productivity with consistent cutting accuracy. When equipped with a flying shear, the line can cut moving material without repeatedly stopping the production process, making it suitable for high-volume coil-to-sheet processing.
Depending on the machine configuration, a Cut to Length Line can process:
- Carbon steel
- Stainless steel
- Galvanized steel
- Pre-painted steel
- Aluminum
- Other coil-fed metal materials
The machine should be designed according to the specific material grade and mechanical properties.
A Cut to Length (CTL) Line is a coil processing system that converts metal coils into flat sheets with a specified length. The line typically performs uncoiling, leveling, feeding, measuring, shearing, conveying, and stacking.
