•The keys and adjusting wrenches must be removed from the machine before operating it. Safety precautions while working with machinery •Stop the machine before measuring, cleaning or making any adjustments. •Do not handle metal turnings by hand as they can cause injury.
· Set the roll nip opening to 2 mm. Adjust and maintain roll temperature at 70 ± 5 degrees C. Add rubber into the mill nip and band, as a continuous sheet, onto the front roll. Using a hand knife, make two ¾cuts from each side and allow the rubber to move through the nip quite a few times until a smooth rolling bank is formed on the nip. Now the rubber is sufficiently masticated and thus ...
