发明名称 Method of drilling of holes into the mantle of a cylinder in a paper machine and equipment for use in the method.
摘要 <p>The invention concerns a method for drilling of holes into the mantle of a cylinder in a paper machine while the cylinder is in its place of operation in the paper machine. In the method, after each cycle of drilling, a multi-spindle drilling machine (10) is transferred along guide rails (12a,12b). In the method, the guide rails (12a, 12b) are supported against the cylinder (S2) adjacent to the cylinder (S1) to be machined, whereby, in the method, before the drilling is started, the drill equipment (11) is tensioned between the mantle face of the cylinder (S1) to be machined and the mantle face of the adjacent cylinder. The invention also concerns equipment for use in the method. <IMAGE></p>
