Operating Instructions

Two-Stage Forming Process

Forming panels with the Berridge TZ-21 is a two-stage operation. 
There are two roll formers mounted on the table for producing 
tapered panels.  One roll former forms the female leg on the coil 
strip (stage 1); the other roll former forms the male leg on the coil 
strip (stage 2).

Panels must be produced using the following sequence of 
operations:

1.  Load a 20-7/8” wide coil on the uncoiler using the same procedure 

as other Berridge Roll formers and thread the coil into the female 
leg roll former.

2. Run panels with the female leg to the desired length.
3. Layout the taper along the unformed strip edge; cut the taper 

and square up both ends.

4. Run the tapered strips through the male leg roll former, completing 

the tapered panels for your project.

NOTE:

 Do not attempt to run both roll formers at the same 

time. This will cause the electrical service to overload and trip 
the circuit breaker.
