  2. Construction and Framework
    1. Welded steel framework with high torsion rigidity
    2. Rubberized counter-roller diameter 400 mm, oil and solvents resistant
    3. Hardness 85 shore A, max eccentricity tolerance ±1/100 mm
    4. A/C gearmotor to drive the counter roller
    5. Roller changing device (bridge) arranged to mount two engraved rollers and one coating knife
    6. Pneumatic lifting of changing device (bridge)
    7. Manual rotation of the roller changing device
  3. Coating and Adjustment
    1. Motorized micrometric adjustment of coating thickness, independent right/left or in tandem, with digital display on control panel, by two jacks
    2. Coating side limiters, manually adjustable either single or tandem
    3. Feeding through in front of the coating knife
    4. A/C gearmotor to drive the engraved roller
    5. Two colour doctor blades (synchro / reverse) with pneumatic opening and closing for a smoother movement of the blade towards the roller, with oscillating movement
    6. Entry idler roller, the upper one liftable by pneumatic pistons for "on air" coating
    7. Piping for the washing of the engraved roller
  4. Fluid Handling and Waste
    1. Two side gutters in stainless-steel with teflon coating, with solvent resistant rubber pipe for wastewater or chemicals collection and recirculation
    2. Wastewater recovery basin, with drain, under the counter-roller
  5. Drive and Control
    1. Manual seam jumper
    2. Variable speed from 2.5 to 50 m/min for the counter-roller and from 2.5 to 99 m/min for the engraved roller
    3. Pivoting control panel with digital screen, mounted on the machine frame, to control and set the machine functions
    4. Main electrical panel equipped with PLC and inverters, protection IP54, mounted inside the left hand machine shoulder
    5. Set of machine accessories and instruction & maintenance manual
  6. Included Components
    1. One coating knife profile
    2. Two positive chromed steel rollers for reverse rotation, engraving to be defined
    3. One pneumatic resin distributor (to – fro) to deliver the chemical across the whole width
    4. One pneumatic piston pump, max viscosity 35,000 cpsa
    5. One level check probe for the automatic start-stop of pump
    6. One automatic seam jumper with sensor, to lift the blade at seam passage
