Abstract: The invention relates to a check weigher comprising a machine body consisting of a front clamping plate and a rear hollow body which is fixedly or detachably connected to said clamping plate and is preferably used as a cabinet for receiving necessary electric and electronic components. The clamping plate is projected on all sides across the hollow body, thereby forming a fastening flange. The outer edge of said fastening flange is provided with a recessed and projected contour which is subdivided into any grid and enables to obtain a positive or non-positive secure connection of accessories with the machine body by means of two clamping plates having a corresponding contour and fixedly connected to a holding plate and additional clamping elements.
