The RAS 21.20
flanging machine
turns up 90 degree flanges on
radius cheeks so that the parts
are ready for Pittsburgh or
Snaplock joints.
Quick. Safe. Efficient.
The speed is adjustable between
0 and 9.4 m/min (0 to 30 ft/min).
In addition the machine can
be operated with 230 V from a
standard wall outlet. The machine
comes with an extended material
support area in front and behind
the forming station.
The large flanging rolls produce
uniform and non-wavy results
even on small radii. Using the
standard rolls variable flange
heights from 6 to 15 mm (1/4" to
5/8") can be formed.
The optional automatic material
guiding system helps to create
consistent flange heights. Rolls
for 8 mm or 10 mm (5/16" or 3/8")
flange heights are available for the
automatic material guiding system.
Rolls in the top attachment pierce
and offset the buttons for the
Snaplock joints in a single pass.
