Description



FIG. 1 is a perspective view of a scraper blade for conveyor belts, showing my new design;

FIG. 2 is a side elevational view thereof, the opposite side view being a mirror image thereof;

FIG. 3 is a top plan view thereof;

FIG. 4 is a rear elevational view thereof;

FIG. 5 is a front elevational view thereof; and,

FIG. 6 is a bottom plan view thereof.

The broken lines shown in the figures are included for the purpose of illustrating portions of the scraper blade for conveyor belts and form no part of the claimed design.

The scraper blade for conveyor belts is shown with a symbolic break in its length by wavy lines in FIGS. 1 and 3-6. The appearance of any portion of the scraper blade for conveyor belts between the wavy lines and the wavy lines themselves form no part of the claimed design.
