METHOD AND APPARATUS FOR CLEANING INTERENGAGING STRETCH ROLLERS |
摘要 |
To clean a pair of counterrotating stretch rollers having surface formations that interengage and that stretch a laminate web transversely to a travel direction in which the web passes between the interengaging rollers gas streams carrying dry-ice particles are directed at surfaces of the counterrotating rollers such that the particles free contaminants from surfaces of the rollers. The freed contaminants and dry-ice particles are aspirated from immediately adjacent each of the rollers while the rollers are rotating and, in fact while the production operation of the web is taking place.
