Instructions for Installing Auxiliary
Rolls
Holding the material against the angle gauge slide it into the forming head.
Be sure that the material remains against the gauge until work is finished.
Note: This machine will handle sheets 7" and longer. If shorter, leave
on long piece — notch and cut later.
Make "Hold-Down Adjustment" to meet any variation in the material of your
locality. Do not adjust unless material slips, tends to leave gauge, or curls
up at finish.
TO ADJUST:
1. Remove top cover.
2. Tighten hold-down studs until snug and then loosen them, a quarter
turn. (This setting will usually give proper adjustment for all thick
nesses of material.)
3. If the material slips, tighten the studs equally until the condition is
overcome.
If the material curls up after leaving the forming head, or shows
extremely heavy pressure marks, loosen studs slightly.
If a wider or narrower hammer-over edge is desired, the angle gauge on
the right hand side can be moved to give the desired width. When moving
this gauge, be sure to move both ends the same distance, keeping it parallel
to the front edge of the top plate of the machine. DO NOT MOVE ANGLE
GAUGES ON THE LEFT OH FINISHING END OF THE MACHINE. THESE
GAUGES ARE NOT INTENDED TO TOUCH THE MATERIAL AS IT COMES
THROUGH.
It
is
very important that long sheets be fed into the machine flat and against
the angle gauge for the start.
IMPORTANT: If proper care is taken, the small knife edge roll that holds
the pocket of the Pittsburgh Lock open will not break. If burrs and twists
from snip cuts are not flattened out, it will sometimes strike against the
opening roll causing it to break.
ANGLE RANGE ROLLS
1. Remove top cover.
DOUBLE SEAM or STRAIGHT RIGHT
2. Remove rear section of top plate. This will expose the
extended shafts on which the rolls are to be mounted.
3
# Select the first pair of rolls, which are marked "Tl" and
"Bl", and slip them on the shafts at the left, or feed side
of the machine, placing "Tl" on the upper shaft and "Bl"
on the lower. Repeat this procedure with rolls "T2" and
"B2"; "T3" and "B3"; "T4" and "B4"; "T5" and "B5" until
all rolls have been mounted. All rolls marked "T" should
be on the top shafts and "B" rolls on the bottom shafts, in
numerical order, reading from left to right, facing shafts.
THE NUMBERED SIDES MUST FACE OUTWARD, OR
TOWARD THE OPERATOR.
4* Fasten rolls to shafts with capscrews, Woodruff keys and
special washers which are provided.
5. Mount gauge on starting side of machine, using slotted
holes provided in top plate. The position of this gauge is
shown below (Gauge Dimensions). The angle gauge on the
finishing side should not touch the metal as it emerges from
Drive
1. Proceed as instructed for Double Seam Rolls, but leave roll
"T-2" loose. This roll centers itself and should not be held
in place with cap screw. Woodruff keys are used in all
cases, however.
2* Remove the stud from the spacer (this is located between
"B4" and "B5") and place the slide block in position, secur
ing it with the 3" stud furnished. CAUTION: ALWAYS
REMOVE THE SLIDE BLOCK AND REPLACE THE SHORT
STUD WHEN TAKING THE DRIVE CLEAT ROLLS OFF THE
MACHINE.
3« Mount the feed gauge on left
hand side so that it is exactly
parallel with the rolls. THIS IS
VERY IMPORTANT! If it is not
parallel, the cleat will not be
perfect.

the rolls.
6« Replace back plate and top cover.
7* Hold material against gauge and feed into machine.
4* Tighten small hold-down studs
so that "T5" and "B5" do not
separate when drive cleats
are passing through.

Lubrication
Check and refill the six grease cups on the under side of the
forming unit at least once a month. The slow speed shafts
do not require lubrication. Check oil in motor occasionally.
If machine is used out of doors an oil or grease film will
prevent rusting of surfaces.

IMPORTANT: Be sure to cut
your material square, and a

!• Remove present cover.
2. Loosen FRONT CAP SCREWS on Spacers No. 1 and 4.
3. Remove Spacers No. 2 and 3 by taking out front and back
cap screws.

To Operate Power Flanging Attachment
Turn gauge adjustment screw all the way in, then back about a quarter

turn. (This setting is usually right for 26 gauge material).
Turn up a* "Starting Flange" on the material before inserting it into the
2.
flanging rolls. This is done by inserting the edge of the piece in the slot
cut in the table top. (Once the operator is accustomed to the Flanger, this
won't be necessary). Slide the piece into the forming head, being careful
to
insert it so that the edge to
ing head. As the metal passes through the forming rolls, be sure to exert
pressure against the piece in the direction indicated by the arrows shown
on the illustration below. This holds the metal to the height gauge, and
results in an even, uniform flange.
After the operator has run a few pieces through, he will become accus

tomed to the "feel" of the machine and will find it easy to hold the metal
to the gauge. The operator should stand in front of the Lockformer for
ease in handling the material.
When flanging straight pieces or pieces having the same radius, the oper

ator
may
set the adjustable guide by running the first piece partly through
the rolls, and then setting the guide against the flanged edge. The guide
should not be set too tight against the flanged edge.
DO NOT HAVE THE GAUGE ADJUSTMENT SCREW TOO TIGHT. It

should be set just tight enough to draw the metal through. Too tight an
adjustment will stretch and wrinkle the material.

IMPORTANT. When flanging small inner radii, such as the throats of

small elbows, grasp the piece in such a way as to have the thumbs on the
under side and the fingers on the upper side of the metal. Then, after hav
ing turned a "starting flange", insert the metal into the rolls and LET GO!
The metal will hold itself to the gauge and produce a perfect flange.
