Description

Application:- To laminate poly film with pharmaceutical grade Aluminium foil by pressure application through rubber rolls in presence of hot drum and to apply a thin coating or shellac on foil surface. Technical Specification:- Materials to be processed : Aluminum Foil, Papers, PE Films Maximum Working width : 1200 mm Maximum Outer Diameter : 1000 mm Maximum Mechanical Speed : 150 Mpm General Specification:- Heating drum is driven by A.C drive system synchronized with re-winder andare dynamically balanced, ground and hard chromed. Pneumatic pressure application system (both side control) for both rubber rolls (hot drum & shellac wash unit)& back up roll. Temperature control of heating drum through submersed electric heater in thermic fluid inside drum and exit of expanded oil through rotary joint. Gravure coating method for shellac wash unit suitable for minimum exposed solvent area. Coating roller-mounting assembly can accept integral shaft type as well as hollow type coating rollers. High velocity drying system equipped with different zone electrical radiator based hot air dryer to dry shellac coating on foil surface. Passing roller inside dryer made from seem less pipe duly chromed and dynamically balanced provided proper web support against hot air. A separate A.C re-winder drive system synchronized with drum drive. Pneumatic brake un-winder tension system with load cell for poly un-winder with suitable controls. Pneumatic brake un-winder tension system with load cell for foil un-winder with suitable controls. All un-winder and re-winder are with air shaft and safety chuck mounting system suitable to adopt paper / metal core. Nos. of adjustable rolls are provided in different positions to compensate gauge variations of any winding defects on foil. A centralized material loading unloading system is there for an easy operation on the center line of the machine. Both of the un-windersare with manual guiding system with liner motion bearing based travelling trolley
