Features for Slitline 35
PLC Drive Automation
Entire machine is controlled and supervised by PLC/PPC. This automation system maintains tight synchronization between PLC/PPC and drives, providing fast, reliable, and errorless communication. Master control panel consists touch screen operator interface located at rewind side
Carefully and methodically machined strong and sturdy heavy duty steel frame structure machined on CNC-VMC, maintains accuracy over long dependable life. Distinctively designed structure ensures less vibration even with optimum line speed. All components undergo extensive tests to ensures optimum performance and longer life of the machine.
Tension Control System
Automatic web tension control system on unwind equipped with pneumatic reel lifting system consists of latest generation AC digital drive and motor with a pair of load-cell. The system maintains tension precisely throughout the reel run up to the core diameter.
Digital web guiding system maintains precision alignment of the web entering the draw unit. The web is guided by edge and printed (continuous or broken) lines. The system consists of camera based digital web guiding system with a linear correction of +- 50mm.
Differential Winding System
Hi-performance differential winding system utilizing ‘Ball lock’ units, ensures constant tension regardless of different width of the reel being rewound on the same shaft. Normal web profile variation is automatically compensated by the differential winding system. It also increases productivity and minimizes ‘downtime.’
Each rewinder is equipped with pneumatically operated lay-on assembly, consists of rubber rollers and backing rollers on a pair of arms
Slit Reel Unloading
Pneumatically operated shaft supporting arms facilitate quick unloading of the slit reels from differential shafts
The machine is well equipped with Razor in Air and Rotary blade in Groove Roller Slitting mechanisms.
