For technical reasons, brake pipes can be only be made in fixed lengths of for example
6 metres. For assembly into vehicles, however, lengths of between 70mm and 800mm
are required. With a machinery installation from Metzner, the pipes are cut into the
required tube lengths at lightening speed (1.2 seconds per tube) and with high precision
(± 0.25mm).
But the demands go further: Because the woven reinforcement can contain defects, the machine
has to recognise faults in the material layers that lie below the surface, reliably cut them out and
automatically separate them.
As the defects can appear in random locations, Metzner is presented with the additional task of
evaluating the remaining good product after the defect location and to cut a selection of different
set lengths, in order to minimise the number of reject parts. Subsequently, parts of the same length
are sorted into different storage containers.
Another new feature is the integral energy-saving concept: If there is a pause in the automatic
feeding of the brake pipes of more than 60 seconds, then the machine switches to an energy-saving
stand by mode and is immediately ready to produce on receipt of the next part.
