Overview
The Berridge TZ-21
Portable Roll Former
produces tapered
Berridge Zee-Lock
panels in a two-
stage operation.
The female leg is
run first from a coil
loaded onto the
uncoiler on the roll
Former table. After
the panel with the
female leg is formed
to the desired length, the strip edge opposite the formed leg is
cut to the desired taper. The strip is then fed through the male leg
machine to complete the panel. See the “Operating Instructions”
section for more details.

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.

Operating Instructions (Cont.)
How to Load Coils:
1. Lock all four casters.
2. Rotate the eccentric tubes (B-2) on the uncoiler by loosening the
nuts on top of tubes (B-1). Then rotate tubes inward to accept the
coil.
3. Load the coil with the painted side facing toward operator side of roll
former, with leading edge toward the machine.
4. Unlock arm of the coil lifter apparatus (C-1), fold legs inward (C-2)
and place inside the coil (C-3). The coil lifter legs should now be
locked in place and the coil should be fully seated on the pads of the
coil lifter legs.
5. Using a forklift or other suitable hoist with a minimum load capacity of
2000 lbs, pick up the coil by means of a chain (sized to accommodate
load) attached to the top of the coil lifter. Keep to one side of coil
and avoid standing underneath coil during the loading operation.
Next, lower the coil onto the uncoiler, and keep it centered on the
uncoiler with the leading end positioned clockwise, ready to feed
into the machine.

Maintenance
Berridge roll formers require minimum maintenance. To insure the
highest quality product and maximum machine life, the following
routine preventive maintenance is required. Keep the machine DRY,
CLEAN, AND DIRT-FREE. This is a precision piece of equipment. Keep
a Maintenance Log.
1. Remove lexan (plexiglass) panels from both sides. Clean the stainless
steel rolls with mineral spirits. Do not spray lubricant on the lexan
panels.
2. Clean the lexan side panels with glass cleaner (Windex or equivalent)
and the aluminum frame with liquid household cleaner. This will
remove lubricant and dirt from the frame.
3. The uncoiler and casters may be lubricated with a good grease.
Lubricate the upper and lower bearing on the uncoiler. Do not apply
grease to the drive gears on No. 1 station as any dirt, paper, etc. on
the coil will collect on the grease.
4. The drive chain may be lubricated with any good quality spray-on
chain lubricant.
5. Main drive gear box:
Grove Right Angle: Uses a 90 weight gear oil
Eurodrive Vertical Inline: Uses SPO-244 by Lubriplate or equal
Rexnord Vertical or Dodge Quantis Vertical: Does not require
lubricant
6. The table can be cleaned with any liquid household cleaner. Touch-
up as needed with Glidden “Bolt Green” paint.
7. Check tightness of all mounting bolts and screws regularly,
especially after each time the machine has been in transit.
