摘要 |
Method and device for drilling holes into a mantle of a cylinder of a paper machine, in particular a drying cylinder, while the cylinder is in its site of operation in the paper machine in which a drill carriage having drill bits is supported on the cylinder being drilled. The drill carriage is locked in a fixed position relative to the cylinder being drilled the drill bits are pressed into the mantle of the cylinder to be drilled and rotating to thereby drill holes in the cylinder mantle. The drill carriage is supported on the cylinder being drilled by a first set of wheels arranged on the drill carriage during drilling and is displaced upon rotation of a second set of wheels which contact the cylinder only for axial movement and not during drilling.
