  • Patent number: 6742759
    Abstract: The invention relates to a mould side system for concrete casts. The magnet unit according to the invention has no movable parts, but the magnet is a fixed component of the unit and detachment is carried out using a simple level tool. The fastening of the mould side to the magnet unit takes place by a known slanted-notch principle. According to an advantageous embodiment, the magnet unit has two faces for fastening mould sides, whereby parallel sides of separate, adjacent moulds may be fixed using the same magnet.
