SLIP ROLL FORMERS 416, 417, 418
These machines are available in three different
sizes. All three models offer the standard front roll
drive. These units may be mounted directly to a
sturdy work bench or to an optional fabricated
pedestal, designed specifically for each unit.

INSTRUCTIONS
CAUTION: Be sure that the machine is securely bolted onto the pedestal or to the customer supplied
bench. Pedestal or work bench should be bolted to the floor.
1. Adjust the Lower Roll to grip the metal firmly and evenly but without straining the machine. The
Lower Roll is adjusted up or down with the two lower Adjusting Screws .
2. Adjust the Rear Roll to form the metal up as it travels through the rollers. The Rear Roll is adjusted
up or down with the two rear Adjusting Screws . Be sure the Rear Roll is parallel with the Lower
Roll. If the rolls are not parallel, the formed metal will be conical in shape instead of cylindrical.
3. Feed the stock to the rolls only from the front.
4. As the front rolls grip the stock, lift the rear end
of the metal upward. This will help reduce the
flat spot on the leading edge of the sheet and
will also cause the leading edge to pass over
the rear roll readily.
5. The diameter of the formed cylinder is determined by the position of the Rear Roll. To increase
the diameter of a cylinder, lower the Rear Roll by turning the two rear Adjusting Screws
counter clockwise. To reduce the diameter of a formed cylinder, raise the Rear Roll by turning the
two rear Adjusting Screws clockwise. The two rear Adjusting Screws should be turned an equal
number of turns in order to keep the Rear Roll parallel with the front gripping rolls.
6. To remove a cylindrical piece without distorting it, lift up the Locking Handle , raise the Right
Hand Housing Cap and turn the Cam Handle down. This raises the outboard end of the Upper
Roll and allows the formed cylinder to be slipped off of the Upper Roll.
7. The Lower Roll and the Rear Roll have grooves of varying widths in one end. These are for the
purpose of accommodating a wired edge when forming a shape or when forming wire into a ring.

SLIP ROLL FORMERS 416, 417, 418
Forming Machines, or Slip Roll formers, are intended for rolling sheet metal or forming cylinders of
various diameters.
The two pinch rolls feed the sheet against the rear roll, curving the sheet and forming the cylinder. The
rear or forming roll can be adjusted by screws on the rear of left and right end housings, varying the
diameter of the required cylinder. Pinch rolls can be adjusted for stock thickness by screws on the
front end of the housings.
The capacity ratings of PEXTO forming machines are based on forming mild steel, fully annealed, the
full length of the rolls and are considered as standard by the sheet metal trade for forming rolls of a
specified diameter and length. Definite capacities, however, depend upon the diameter and length of
the cylinder to be formed and the number of passes through the rolls to obtain a given diameter.
Stiffness of material and uniformity desired are also factors. When a forming machine is overloaded,
the immediate result will be deflection in the center of the rolls, resulting in cylinders bulged in the center.
Three inch diameter forming rolls have longitudinal grooves in the rear forming roll to assist in starting
the sheet. Forming rolls 3” in diameter and larger have all three rolls driven as standard. Three roll
drive for rolls under 3” in diameter at extra cost.
In order to reduce the number of rear roll adjustments when sheets are of light gauge, proceed as
follows:
1. Insert the sheet between two pinch rolls.
2. Bend the sheet upwards and slightly around the top roll.
3. Continue to pass the sheet through the machine.
This will also reduce the flat spot on the leading edge of the sheet.
The right-hand housing is provided with a hinged journal cap and lifting latch. After the cylinder is
formed, the latch is lifted and the lever is pressed down. This raises the top roll and the cylinder can
be slipped off the roll without distortion.
Forming machines are provided with grooves in the right end of the lower and rear rolls to allow for
forming cylinders with a wired edge.
WARNING: Before operating, machines must be bolted to the work bench. If the floor stand has
been provided, machine must be bolted to the floor stand with bolts provided. Stand
must be securely lagged to the floor.
