Automatic Double Die Flanger and Bottom Seamer
This machine serves for the production of cylindrical cans
with side seam welded or lock-seamed. The can bodies fed
by an inlet chute
are flanged by means of dies, a system allowing an exact
calibration of can bodies, particularly recommendable for
the following bottom or lid
seaming. Then bottom or li dseaming is effected at stationary
cans by means of 4 seaming rollers (two of first and two
of second operation), which guarantees an absolutely sure
closure. The operator's intervention is limited to feed curled
ends in the stacker, equipped with separatine sliders, as
can bodies are automatically carried from a working station
to the other by means of star conveyors. Movements of can
bodies and end feeling are controlled by contactless sensors
stopping the machine in case of missing feed of bodies and
ends or excessive effort of star conveyors due to jammed
bodies or ends. Instead of being flanged, the free body end
can be inside or outside curled for the application of pressare
lids or be broadened (only for welded can bodies) to produce
stackable cans. Also rings with aluminium foil and pressare
lids for coffee cans, milk powder cans etc. can be seamed.
This machine, furthermore is designed to be couplet to the
horizontal seamer mod. S.121 to obtain the transfer assembly
mod. STAV 175+S.121. For its great versatility the machine
has a wide range of application.
Now also in execution mod. STAV 175/DN, equipped with a supplementary
- die necking at one can end for staclable cans
- double die necking at both ends, equal or differential
Diameter range: 52 to 175 mm.
Can heights: 80 to 320 mm
Max. welding overlap: 0,8 mm.
In the version mod. STAV 175/DNC the machine can also make
an inside curl on lock-seamed can bodies, an operation which
is effected in the flanging station opposite the seaming
head by means of a inner profiled die and expandable inner
male to keep the lock-seam.
All cams, gears and the 8-position indexing device run in
an oil bath and all parts with rapid rotation are mounted
on ball or needle bearings.
In the actual version the machine is equipped with separate
control board cubiche, micro-lubrication system with programmable
cycles, parts of mechanical movements treated with anti-seizure
ionic nitriding and easy opening drive protection.
CHANGE OF CAN SIZE: in about one hour for the change of can
diameter and only a few minutes for the change of can heuight.
MOTORIZATION AND OUTPUT: the machine is
equipped with a 3.75 kW 350/1750 r.p.m. motor and inverter,
