This retrofit eliminates the possibility of the pressure roll in the 380SF singlefacer from becoming damaged by the scraper mounting bar. With the old design scraper assembly, when the blade was worn to a certain point and it was not replaced, the mounting bar could come into contact with the pressure roll and damage it.
With this design, the scraper requires no adjustment by the operator, and is held against the roll by spring tension. This eliminates the operator being able to over-tighten the blade adjustment to try to clean up the pressure roll from mis-set dams. There is also a positive stop so that when the blade wears out, it will no longer scrape properly, thus making the operator aware that it must be replaced.
