MODEL 600-R3 SERIES DOUGH MOULDER
1.0 DESCRIPTION / SPECIFICATION
1.1 Description
The moulder stretches dough gently and gradually between two belts revolving in
opposite directions and at different speeds. The dough is inserted in a hopper located
approximately 54" from the floor (when mounted on the Oliver Moulder stand with
casters), which feeds it between three plastic coated sheeting rollers. The sheeting
and stretching operations are controlled manually with two levers with easy to read
scales.
The moulded dough is delivered below the hopper on a felt covered retractable shelf
approximately 32" above the floor (when mounted on the Oliver Moulder stand with
casters).
All driving cylinders are mounted on sealed bearings which are lubricated at the factory
and need no further lubrication. The front belt rotates on three cylinders positioned in a
triangular pattern while the rear belt rotates in the opposite direction on two cylinders.
The three plastic coated sheeting rollers, (of which the lower one is adjustable), flatten
the dough after it is inserted in the hopper.
The moulder is driven by a 3/4 HP open drip proof motor which is easily adjustable for
tightening the V-belt drive. The revolving belts are driven by a noiseless gear belt
system which never needs lubrication.

2.0 MACHINE INSTALLATION
2.1 Electrical Requirements
First, check the wall receptacle to be sure it is a three phase, 230 volt receptacle. If not,
one must be installed. Attach a three phase, 230 volt plug to the end of the power
cord. Be sure the pattern of the wall receptacle and pattern of the plug are matching.
A TWIST-LOCK TYPE PLUG MUST BE USED ON THE 600-R3 SERIES OF
DOUGH MOULDERS POWER CORD TO KEEP IN COMPLIANCE WITH
Before putting machine into operation, check to see if the machine is running in the
correct direction. (See Section 2.2).
2.2 Machine Running Direction
To check for proper running direction you must first disengage the heavy mat, (Item
#808, Assembly Drawing 5.1.1) by removing the left and right heavy mat support
springs (Item #809, Not Shown) from their posts located towards the top. Lay the
heavy mat and under lying felt over the front of machine. Then switch the machine on
briefly and observe the direction in which the front triangular belt is moving. If the belt
is moving upward the belt rotation is correct. If the belt is moving downward the
machine’s running direction must be reversed. Unplug the machine from the power
receptacle. Reverse the black and white wires in the plug at the end of the power cord.
When the running direction of the machine is correct reinstall the heavy mat.

3.0 OPERATING INSTRUCTIONS
3.1 Machine Preparation
Always flour the delivery outfeed table felt generously and thoroughly. You should also
flour the dough as thickly as possible, all around. Also, when preparing to run the
moulder we recommend that you first weigh as many pieces of dough as possible in
advance.
3.2 Establishing Settings
ADJUSTMENTS SHOULD BE MADE WHILE THE MACHINE IS RUNNING.
Gently drop a piece of dough in the hopper and observe its shape after moulding.
• If the loaf is too compact, open the sheeting rollers.
• If the loaf is not compact enough, close the sheeting rollers.
• If the loaf is too short, close the rear chamber.
• If the loaf is too long, open the rear chamber.
• If the loaf is too fat in the center, close the sheeting rollers while sheeting, or, the
dough may be too stiff.
• If the ends twist, open the rear chamber.
We recommend that all settings be recorded for later use once they are established.
Remember, results may vary depending on dough condition. If required, make
adjustments gradually starting with the original established setting.
