per hour. The tubes come from production
on a roller conveyor to the preservation
line, where an oscillating lifting system
(‘walking beam system’) transfers them to a
measuring system where length and weight
are recorded. These measurements and a
serial number are stenciled into the tube.
The next step is the transfer of the tubes to
the pre-heater with a cross-chain-conveyor.
In the pre-heater, the tubes are heated up
to 40°C (104°F). The actual coating takes
place with a water-based lacquer with 2 sets
of spray guns that are arranged in a circle
to reach the complete parts surface. The
spray positions are automatically adjusted
in line with the tube diameter.
After painting, the parts pass through
a drier. After stenciling, the parts are
transferred to a packing station equipped
with a vacuum lift system where they are
collected in bundles. The number of vacuum
suction units, which package the tubes into
a hexagonal shape, depends on the length
of the tubes. The strapping of the bundle is
achieved with steel straps.
At the preservation line for Perwouralskij
the parts arrive not in single file, but are
placed in bundles by a crane on the Rösler
preservation line. In the first step, the
tubes are separated, and then weighed
and length-measured. The tubes are then
transported to a brush station. Parts not in
line with proper specifications are moved
to a ‘non-conforming’ parts station. In the
brush station, after the parts are identified,
loose dirt and rust is removed from the
tubes. After pre-heating, the parts are
transferred to the paint booth.
A light curtain signals the system not only
when a part passes through the paint booth
but also the parts size. This ensures that the
21 airless high-pressure paint guns are only
spraying material, when parts are passing
through, and that the gun placement is
adjusted in line with the parts diameter.
After drying, the tubes are transferred from
the slat conveyor to a cross-chain-conveyor,
which transfers them past a marking station
to the packing station.

international market leader in the production
