  5. General Drive
    1. Main motor inverter control and mechanical transmission with differential gear boxes, cardon and timing belt.
    2. SAP and fluff application are controlled by independent motors, inverter controlled, and the value can be set and displayed on the touch screen.
  6. Conveyor Belt System
    1. Under vacuum belts, allowed along the machine, are provided to pull and to drive the web.
    2. A special valve is provided to adjust the vacuum level under the belt.
  7. Raw Material Unwinding Units
    1. Full automatic unwinding modules are allowed in line in order to drive and to control the tension of: back-sheet, back sheet NW, central NW, cuff NW, ADL.
    2. Each of these units is driven and controlled by variable frequencies motors to unwind through the spindle shaft, alternatively, the two rolls of raw material and a splice equipment to join and cut the starting and the finishing roll.
    3. A dancer, a metering device and an edge guiding unit complete each unwinding module.
    4. 1 set for side NW before splitting, 2 sets for side NW after splitting; 1 set for central NW.
    5. 1 set for back sheet, 1 set for frontal tape, 1 set for cloth-like lamination, 1 set for ADL, 1 set for waist band, 1 set for backsheet NW.
    6. Totally 10 sets web guiders equipped on the machine.
  8. Automatic Quality Control System
    1. This system includes hardware and software for an automatic control of the following diaper parameters: fluff missing, frontal tape missing, fasten tape missing, leg and cuff elastic missing, diapers reject at every line start-up, presence of raw material cutoffs.
    2. If diapers do not meet the preset parameters, the faulty product will be automatically rejected through the reject gate.
  9. Pulp Unwinding Support (2 Sets)
    1. 2 rolls of cellulose pulp, max diameter 1400 mm and width 508 mm, including water spray system, are allowed on the pulp stand to feed mill.
    2. A pulp unwinding support is prepared for each set of mill.
  10. Drum Forming Module
    1. Two drum formers are installed on the machine with interval pockets forming, to produce a pad in accordance to the customer needs.
    2. Fluff chamber directly connected to the high speed cell mill installed on the top of the module for each drum former.
    3. Take away system to pick up and to compact the fluff layer are part of the module.
    4. The conveyor belt, already conveying the glued back sheet, receives the fluff and moves it to the next station.
  11. High Speed Cell Mill
