what is Label Stock Converting Solution?
Label stock converting refers to the industrial process of transforming jumbo rolls of pressure-sensitive laminate materials—typically consisting of a face material, adhesive layer, and release liner—into precisely slit and rewound rolls ready for label printing, die-cutting, or final application. This process is fundamental to the label manufacturing industry, ensuring that each roll maintains consistent tension, alignment, and edge quality throughout production.
At Jota Machinery, the label stock converting solution integrates advanced mechanical design with intelligent control technology to achieve exceptional precision and operational stability. Each system is equipped with PLC control and HMI touch interface, allowing operators to set and monitor key parameters such as unwinding diameter, web tension, slit width, and rewinding length with high accuracy. Through servo-driven tension control, the system maintains uniform web tension across materials of varying elasticity, preventing curl, telescoping, or misalignment during high-speed production.
JT-SLT-1300F Label Stock Roll Slitting Rewinding Machine
The JT-SLT-1300F is a high-precision slitting and rewinding system engineered for label stock, paper, film, and laminated materials. It integrates a PLC control system with a touch-screen HMI, ensuring accurate tension control, stable running, and consistent slitting quality at speeds up to 300 m/min.
A hydraulic unwinding unit, EPC web-guiding system, and servo-driven transmission enhance efficiency and operator safety. Built with a 50 mm thick machine frame and CNC-processed components, the JT-SLT-1300F provides long-term reliability and precision performance for continuous industrial production.
