Abstract
A paper stock modification device is provided wherein accretions do not build up on the blades even when modifying paper feedstock comprising large amounts of hot melt, adhesive material, etc. and there is no risk of damage to the cylinder. Since a circular member is provided in a space at the other end, the paper feedstock accumulates in front of the end face of the circular member and is in a softened state with moisture removal being incomplete. Metal scraper parts protrude therein and the metal scraper parts are in close proximity to blades. Thus, even if paper feedstock comprising large amounts of hot melt, adhesive material, etc. adheres to the blades, the same is completely scraped off as a result of a scraping action of the plate surfaces of the metal scraper parts that is caused by the rotation of the blades.
