Roll-Up Tray
The roll up conveyor continues the rolling action
after the roll has passed the starter tray. This
conveyor should hang about 2” above the starter
tray, when the conveyor is empty. The measurement
is taken from under the front curved guide bars (1) to
the top of the starter tray frame.
Adjustments to the height of the tray is made with
the chain (2) which connects the support spring to
the roll-up tray.
The speed of the roll up mat is timed by means of
sprockets and chain which are driven by the
conveyor drive motor. The unit is set at the factory to
the average operating speed for the specified sod
length. Sprockets may have to be changed to suit
various lengths and conditions, see chart in parts
manual page 74.
The front idler assembly must be set so that the mat
is almost touching the front cross member, so that
the sod does not enter this space, and disrupt the
roll.
The rear idler assembly is adjustable to allow for belt
tension. When the top section of the rubber belt is
pressed down there must be at least 2 ½” between it
and the bottom section of the belt.
OPERATION
With the mintex belt, the mat should be slack and
the pressed down dimension should be 1 ½”.
When adjusting the rear shaft to tension the mat,
make sure that both the front and rear shafts are
parallel to prevent “cone shaped” rolls.
Roll-Up Tray Stops
A roll-up tray stop (3) with a urethane bumper pad is
bolted to each side of the conveyor frame, and a pair
of bearings (4) is bolted to each side of the roll-up
tray. Replace the bearings or the roll-up tray stops, if
they become excessively worn or damaged.
