Jul 20, 2013· 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 ¾-cuts 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.
Rubber Processing and Shaping • Two basic steps ... Two stages of mixing, masterbatch (non-vulcanizing agents) and second stage (vulcanizing agents), using two-roll mill and internal mixer • Shaping – Extrusion, calendering, coating, molding and casting • Vulcanization – A curing (cross-linking) process developed by Goodyear …
2-High / 4-High Mills These mills may be converted for either 2-High or 4-High operation by the removal or insertion of work rolls. This permits great versatility of rolling capability on the same mill.
