It is Easy way , Before then roll finish, with 5-7 minutes , just move the sheet from roll , and replace the roll, and after That before the end of the roll going to the chain stick new One on the top end after just put the Machine on 2 ( i mean not forming ) till when double sheet pass the tool, and after That start forming again ( i Work on thermoforming and before takes 10-15 minutes roll change + diferent temperature FOR new roll , and not good quality FOR Another 5-6 min , But in this way the roll change is 1-3 minutes and quality is Spot on )
