INSTRUCTIONS
CAUTION: Be sure that the machine is securely bolted onto pedestal or to customer
supplied bench. Pedestal or workbench should be bolted to floor.
1.
Adjust Lower Roll (11) to grip the metal firmly and evenly but without straining the machine. Lower
Roll (11) is adjusted up or down with the two lower Adjusting Screws (29).
2.
Adjust Rear Roll (12) to form the metal up as it travels through the rollers. Rear Roll (12) is adjusted
up or down with the two rear Adjusting Screws (22). Be sure Rear Roll (12) is parallel with Lower
Roll (11). If 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 (12). To increase
the diameter of a cylinder, lower Rear Roll (12) by turning the two-rear Adjusting Screws (22) counter
clockwise. To reduce the diameter of a formed cylinder, raise Rear Roll (12) by turning the two rear
Adjusting Screws (22) clockwise. The two rear Adjusting Screws (22) should be turned an equal
number of turns in order to keep the Rear Roll (12) parallel with the front gripping rolls.
6.
To remove a cylindrical piece without distorting it, lift up Locking Handle (27), raise Right Hand
Housing Cap (1/2) and turn Cam Handle (15) down. This raises the outboard end of the Upper Roll
(10) and allows the formed cylinder to be slipped off of the Upper Roll (10).
7.
The Lower Roll (11) and the Rear Roll (12) 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.
8.
"X" points should be lubricated daily with a good grade machine oil. "Y" points should be greased
weekly with Alemite #33 or equal.
