10.8. SETUP OF THE SCRAPER ANGLE
Allen screwdriver 4 mm
The scraper angle can be set in 3 different positions. Depending
on the product, it might be required to adjust the angle for
removing the product.
For this purpose, scraper bolts with different lengths are
screwed to the scraper socket to change the tangent angle of
the scraper knife to the roller.
The table below contains the corresponding tangent angle for
the length of the scraper bolts.
Scraper bolts
Tangent angle scraper knife - roller
1 mm
approx. 110°
4 mm
approx. 115°
8 mm
approx. 120°
Fig. 54: Mounting the scraper bolts for different scraper angles (tangent angles)
1. Screw off both scraper bolts with an Allen screwdriver.
2. Clean both receptacle holes.
3. Mount the scraper bolts of the desired length and tighten with Allen
screwdriver.
The different scraper angle positions might render it necessary
to adjust the scraper contact pressure.
The higher the tangent angle, the higher the scraper contact
pressure needs to be, and vice versa.
