0040] The thickness of the anti-debris filter plates is
0.5 ... 1.0 mm. The plates are connected to each other
"groove in the groove". For increasing the joints strength
and the elements rigidity of an anti-debris filter, the plates
can be welded to each other, as well as to the rim 22 by
means of laser, electron-beam or argon-arc welding.
[0041] The claimed anti-debris filter can be made of
stainless steel type X18H10T with the use of modern
digital high-performance gas-laser cutting technology,
mastered in mass production. This anti-debris filter also
can be made of stainless steel, using additive technologies.
