strip with the layer 6 can be shaped to a ring, as
shown in Fig. 4 by reference number 8. Preferably,
before the bending of the metal screen or the
perforated strip 1 with the applied layer 6, the edges
are first cut to the desired width of the grinding
disc.
After closing of the metal screen or perforated
strip 1 with the applied sintered layer 6, a
cylindrical bearing section 9 is inserted into the
inside of the ring 8, and ring 8 is bonded to the
circumference area 9a of the bearing section, whereby
an appropriate intermediate layer 10 may be used
[translation, page 3].
The German reference adds that the bearing section
9 comprises mainly plastic (see page 4 in the translation), and
that the resulting disc has a strong abrasive layer and is
inexpensive and relatively light due to the small cross-sectional
area of the ring 8 as compared with the cross-sectional area of
the bearing section 9 (see page 3 in the translation).
