NOTE: Positive crown is when the middle of the mat
is raised to permit water to drain to each side.
Negative crown is the lowering of the center of
the screed plate. Negative crown might be used
in an alley where drainage down the center of the
alley is necessary (Figure 6-18).

NOTE: Crown may be placed in the leading edge and/or
the trailing edge of the screed plate. Crown in the

plate only. Trailing edge crown puts a crown in
the mat.
Example: trailing edge crown is 0, leading edge
crown is 1/8 in. With this setup, there will not be any
crown placed in the mat laid by the LeeBoy Model
8616 Conveyor Paver; however, material ow under
the screed plate will be improved.
NOTE: Leading edge crown is set at 0 when shipped
from the factory. The chain connecting the
leading and trailing edge crown control assures
that the relationship of the edges remains
constant as the trailing edge is changed to meet
job conditions.
