The stationary, or top, roll is secured at its left
end to the gear side of the machine with the cap
screw and jam nut (see Figure 1). These can be
adjusted if needed.
Foot Pedal Operation
The shrouded foot control has pedals for instant
forward or reverse motion.
Push the emergency stop button for fast shut
down of the slip roller. To re-start the machine,
rotate the emergency stop button clockwise until
it releases.
Forming the Workpiece
The rolls present a pinch
point and/or crush hazard. Do not place
hands in close proximity to the rolls while
operating.
Material Size Considerations
To determine the approximate length of material
needed for a desired size tube, use the following
formula:
DC
π
=
where
C
is the circumference,
π
equals 3.1417
and
D
is the diameter.
For example: To find the length of material
needed (C) to form a tube 4" in diameter,
multiply 3.1417 by 4". Result: 12.5667" is the
circumference of approximate length of material
needed. Cut several pieces of material to this
length for a forming test run. Material may have
to be lengthened or shortened depending upon
results of the test run.
If the workpiece is large, make sure it receives
proper support as it exits the slip roll machine.
Flat Rolling
Softer metals (copper, aluminum, etc.) can be
processed through the slip roll machine to
straighten, flatten, or reduce their thickness.
Simply adjust the pinch roll for thickness, lower
the idler roll all the way down, and feed the
workpiece through (Figure 2).
NOTE: The idler roll will not descend completely
out of the path of the workpiece; thus, there may
be a slight bend in the workpiece. By flipping the
workpiece over and re-feeding it, this bend can
be minimized.

Forming a Radius
1. Adjust the pinch roll as needed.
2. Turn on the slip roller and insert the
workpiece from the front. Make sure the
stationary roll is rotating counter-clockwise.
3. When the material reaches the point where
the radius is to begin (A, Figure 3), stop the
machine and raise the idler roll an equal
amount on each end to achieve the desired
bend.
4. Re-start the rolls and continue until the bend
is completed (B, Figure 3). Support the
workpiece as it exits the machine.
5. If a smaller radius is needed, adjust the roll
distance and re-feed the workpiece.

Forming a Tube
A tube can often be made with a single pass
through the machine, as follows:
1. Adjust the pinch roller as needed to
accommodate workpiece thickness.
2. Feed the workpiece into the machine. As it
nears the end (Figure 4a), stop the machine
and reverse direction (Figure 4b).
