  2. Unwinding Group Model Ut2/As
    1. Item 001: Unwinding trolley for large rolls, model UT2
    2. Item 002: Axial unwinder, model AS, with universal fast joint for unwinding trolley connection coating head, model BS2
    3. Designed and built so that different coating techniques can be employed
  3. Lamination Unit Mod. At2
    1. Item 003: Unwinding group to pull the material requiring lamination without tension
    2. Item 004: Lamination unit consisting of:
      1. Two cylinders heated with diathermic oil (Ø 2000 mm)
      2. Stainless steel surface, covered in Teflon
      3. One lamination rubber cylinder (Ø 200 mm) opposite to the first cylinder
      4. Cylinder motion obtained through a pneumatic piston with adjustable pressure and equipped with motorized micrometric adjustment of lamination thickness
      5. Two release idle cylinders opposite to the two main cylinders
      6. Idle cylinders to pass material
    3. The unit is driven by an A.C. motor with inverter and local potentiometer for line synchronization, and is equipped with a pump for oil circulation and thermoregulation
  4. Rewinding Group Mod. Ut2/As
    1. Item 005: Rewinding trolley for large rolls, model UT2
    2. Item 006: Axial rewinder, model AS, consisting of a lateral supporting structure with asynchronous induction motors A.C. motorization and control panels, model QE
  5. Unit For Dry-Coat Process
    1. Item 007: Moving unwinder mounted on wheels and running on rails; it can be placed before the first heating cylinder and unwind material that requires lamination, or after the second heating cylinder and function as a “dry-coat” unit
    2. Item 008: Calendering unit consisting of:
      1. Counter-cylinder covered in neoprene of adequate hardness
      2. Steel upper calendering cylinder
      3. Pressure between the two rollers is controlled by two pneumatic pistons which can be accurately adjusted in order to obtain uniform pressure all along the width of the table
