Wax/Hot Melt coating on Aluminium foil laminates through three roll transfer coating method.

Wax/Hot Melt coating is done involving three roll transfer coating method. Coating control is achieved through pressurized rubber roll driven separately.

Separate pneumatic application for bath roller, applicator roller & impression roller.

Both the chilling rollers are friction driven with spiral circulation.

Synchronized independent drives are provided for following

Hot melt application (Main Drive)

Primary un-winder

Secondary un-winder

Rewinding unit

Cat walk along the machine length provides easy access to the whole machine

Sturdy body frame construction enables high speed coating without vibration

Heavy duty gear box

Load cell based tension control unit at both unwind station

Chilling roller before rewind unit and after coating unit.

Passing roller --- Made from 100 mm dia heavy duty alu pipe, polished & dynamically balanced at 4000 rpm.

All transmission through timing belts and pulley.
Un-winder and re-winder are with safety chuck and air shaft type mounting system.

Separate melting tank along with distribution line with hot oil circulation and jacketed tray for application unit.
Supply of a separate inbuilt hot thermic fluid heating system is optional.

All motors are of L&T or ABB make.

All drives incorporated are digital AC Drives of Parker or Siemens make.

Auto tension control is through load cell and encoder arrangement.

Web Guiding System is of E+L make.
