Abstract: The invention concerns a method for making the foundation slabs of a paper machine. In the method, reinforcement strands are fitted inside a mold for a base beam. Before filling-concreting of the mold, a base slab provided with a plurality of foundation bolts is installed in connection with the reinforcement strands and preferably on support of said strands. After the slab has been installed as sufficiently planar manner with its face horizontal, the filing-concreting of the base slab is carried out. Upon drying of the concrete cast, the final tightening of the foundation bolts of the base slab is carried out. The ultimate machining of the base slab is carried out on site in the mill space by passing a machining device supported by guides rails which have been adjusted to a horizontal level along faces of the base slab.

Abstract: A method and apparatus for drilling holes into the mantle of a cylinder in a paper machine while the cylinder is in its place of operation in a paper machine is disclosed. After each cycle of drilling, a multi-spindle drilling machine is transferred along guide rails supported against a cylinder adjacent to the cylinder to be machined. Prior to drilling, the drill equipment is tensioned between the mantle face of the cylinder to be machined and the mantle face of the adjacent cylinder.
