<p>The present invention relates to an arrangement for shaping grinding material, particularly for bevelling belt preforms (10) manufactured of flexible grinding material. The belt preform is transported along a counterpart (11) and simultaneously treated from the side opposite to the counterpart by a grinding member (12) pressed against the belt preform. In the invention, the counterpart (11) comprises at least one rotating member with a substantially cylindrical outer surface (14). Allowing the belt preform to rotate over the counterpart reduces the stress it is subjected to, whereby the counterpart's lifetime can be lengthened considerably.</p> |
