摘要

The machine has a drilling band (4) guided around a cylindrical shaped exchangeable working roller (6) and a drive roller. A clamping roller is freely rotated around a clamping roller axis. The clamping roller is movably supported at a clamping roller frame at a side such that the clamping roller is aligned along a running direction of the drilling band between the drive roller and the working roller at different angular positions. The clamping roller and the drive roller include a bearing surface that is curved in an inward direction.
