    II. Facing sheet profiling part
    A. Equipment used
    1. Decoiler                                          2 sets
    2 Film coverer                                     2 sets
    3 Forming machine                              2 sets
    4. Hydraulic cross-cutter                       2 sets
    5. Flipper                                           1 set

    B. Production process
    ● Facing sheet profiling part divides into two lines.
    ● One line is for forming outer roof.
    ● The other line is for forming inner roof as well as for outer and inner wall.
    ● Each line is made up of one decoiler, one film-coverer, one forming machine, one hydraulic clipper and one group of roller conveyors.
    ● Facing sheet after being decoiled and formed is cut into required length by a hydraulic clipper while the forming machine stops running.
    C. Constituents of equipment
    1.Hydraulic decoiler
    It is used for unwrapping and hydraulically tensioning color steel with the coil of ∮508mm in internal diameter and 1,250mm in width and maximum load of 10T. The decoiler includes a hydraulic loading trolley. Power: 4.5kw.
    2 .Forming machine (profile drawing attached)
    This machine is used to form color-steel facings, having plate like structure, welded frame and gear-chain transmission.
    Specification of color-steel facings for wall panels and internal roof: 1,000mm in width and 0.35~0.8mm in thickness.
    Specification of color-steel facings for external roof shall be 1,200mm in width and 0.35~0.8mm in thickness.
    For forming external roof, the machine shall be with 21 pairs of forming rollers of 75mm in diameter and with the power of 5.5kw, maximum forming speed 8m/min variable by changing frequency.
    For forming wall panels and internal roof, the machine shall be with 10 pairs of forming rollers of 75mm in diameter and with the power of 4kw, maximum forming speed 8m/min variable by changing frequency.
    3. Cross-cutter
    It is employed to hydraulically cut forming color-steel facings into pre-determined length at request with a guillotine actuated by the hydraulic station of decoiler. PLC controller and length detector are adopted.
    4. Film-covering installation
    This installation is used to cover film to the surface color steel before forming in case of scratch. Size of a PVC film coil: ∮72~80mm(inner diameter); ∮400mm(outer diameter).
