Abstract
The present invention relates to a method that allows the automatic and hands-free threading of a calender set of rolls comprising one or more pairs of rolls that have a nip between them by preventing the skim from sticking to a roll undesirably as it exits the nip. This is particularly useful during startup or when the continuous running of skim through the calender is interrupted or broken. This method also comprises steps that help prevent the interruption of the calendering process including the breaking of the skim being processed. The steps for startup include running the rolls to which the elastomeric mix is desired to stick at slower speeds than other rolls. The steps for maintaining continuous running of the calender after startup include running the rolls to which the elastomeric mix is desired to stick at faster speeds than other rolls.
