Abstract (en)
[origin: EP0870902A2] Adjacent cutters (2,4,6,8,10) work in individual guides in a guide system which supports the cutter casings in the peripheral direction. Adjacent cutters (4,8) on both sides of a middle one (6) have mechanisms (18) correcting the latter in the peripheral direction. Each guide comprises a link (16) fitting in a mounting (12,14) on each lengthwise side of the cutter, and coupling adjacent cutters together. One of the mountings cannot slide in the driving direction in relation to the link. The latter can be arranged to turn in its mountings.
