Abstract

A mechanism for operating a needle board in a needling machine comprises two reciprocable rods which serve to operate the board and each of which, together with the associated eccentric drive, is mounted in a bearing housing. To permit an adaptation of the rod spacing to a desired board length, the two bearing housings are rigidly interconnected by at least one spacer to form a flexurally stiff structure.
