EXIT GAUGE
Never move the exit gauge bar for this roll set. This gauge is not intended to contact the material
under normal circumstances.
NOTE:
There should be a deep scribe or scratch mark
along the side of the exit gauge, this is the original line
location of the exit gauge from the factory. Slight
adjustment from this line may be required.
1.
DISCONNECT POWER
2.
Install lock outs to prevent accidental start up.
3.
Remove the cover.
4.
Unscrew and remove the right hand side table top section. This will expose the auxiliary
shafts on which the rolls will be mounted.
5.
Select the first pair of rolls which are marked T1 (Top roll first station) and B1 (Bottom roll first
station). Slide them as a mated pair onto the shafts. All information stamped on the rolls must
face outward. Slide a key into each keyseat. Follow this procedure in sequence with each
remaining pair of rolls.
6.
Fasten the rolls onto the shafts with the screws and washers provided.
7.
Mount the entrance gauge and set it to the dimensions shown in the illustration.
8.
Mount the exit gauge so the outside face of the vertical leg is parallel to the part as it passes
over the exit table. Set to allow approximately 1.5mm clearance between the part and the exit
gauge.
DOUBLE SEAM or STRAIGHT RIGHT ANGLE FLANGE ROLLS
!
CAUTION:
The flat roll (called the opening roll) mounted horizontally after the last roll station
maintains the opening of the gap in the PITTSBURGH lock. Twisted or bent notches should be
flattened prior to feeding stock material into the machine. Failure to do this can result in breakage
of the opening roll.
OPENING ROLL
NOTE:
Standard auxiliary rolls are interchangeable between the standard LK 20 and the Super-
Speed models. Since different entrance gauges are required, the model for which the rolls are
intended should be specified.
