A shaft (1) for a disc filter comprising circumferentially to the shaft (1) adjacently positioned casing parts (5), which casing parts (5) are substantially parallel with the longitu-dinal direction of the shaft (1) and which casing parts to-gether form a casing (6) of the shaft (1). At least one cas-ing part (5) comprises at least one fold (11) substantially in the longitudinal direction of the shaft (1) in such a manner that at least one casing part (5) comprises, circumferen-tially to the shaft (1), at least two planar casing portions (5', 5") which are at an angle (.alpha.) to one another.
