Tin Knocker 2236 Rolls

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 front of end
housings.

The capacity ratings of Tin Knocker 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
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.

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 work bench. If floor stand

has been provided, machine must be bolted to floor stand with bolts provided. Stand must be
securely lagged to floor.

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.
