Definitions
- Such scrapers are used, for example, in the paper industry. Here, they serve to clean the surface of rolls, but also the decrease of the paper web of a roll shell, for example, the coat of a drying cylinder.
- the scraper bar can be hollow. This offers the possibility to accommodate the additional mass inside the scraper bar.
- the additional mass can also be provided outside the scraper, for example in a housing.
- a scraper device 5 extends over the cylinder 1.
- the scraper device 5 comprises a scraper bar 6, a blade holder 7 and a scraper blade 8.
- the scraper blade 8 is set against the lateral surface of the drying cylinder 1.
- the doctor blade 8 takes the paper web, which may be largely dried depending on the configuration of the dryer section, from the lateral surface of the drying cylinder 1 from.
- the third embodiment of the invention shown in FIG. 4 shows a hollow scraper bar 6 with a high-viscosity liquid 12, for example a gel, enclosed therein.
- a high-viscosity liquid 12 for example a gel
- an additional mass 9 is embedded, which rests loosely on the bottom of the scraper bar 6.
- other liquids come into consideration, such as oil or water.
