摘要:
The invention relates to a method for drilling holes in the shell of a paper machine cylinder (s2), with said cylinder being unremoved from its operating position in a paper machine, in which method a drilling apparatus (1) is fixed to the adjacent cylinder (s1). In the method, the influence of mechanical play in the structures of said adjacent cylinder (s1) is eliminated prior to drilling. The invention also concerns a compatible apparatus.

The invention relates to a method for drilling holes in the shell of a paper machine cylinder, with said cylinder being unremoved from its operating position in a paper machine, in which method is utilized a multispindle drilling apparatus (1) equipped with a facility of controlling the distance between the drill centers of the adjacent drilling modules (7). The multispindle drilling apparatus uses drilling modules (7) of at least two spindle heads, whereby the mutual distance of the spindle shaft centers (19, 19') in each drilling module is adjusted by rotating the spindle heads of at least one drilling module about the intermediate shaft (15, 15') of the drilling module. The invention also concerns a compatible apparatus.
