(step 5) adjustment and control of placement state: and (4) hanging and placing the composite coil stock in a curing chamber to achieve the curing purpose.
Further, the hardness of the rubber roller in the step (1) is enhanced by 20-30%, and the pressure of the rubber roller is enhanced by 10-15%.
Further, the checking mode of the compound process in the step (2) is carried out through a vision probe, and whether the paving performance of the rolling appearance state reaches the standard or not is scanned.
