  • Patent number: 4736479
    Abstract: A method of beekeeping in which a super is placed on a queen excluder positioned over the brood chamber of a bee colony, the super having a bottom cover and a top cover board which are provided with slots and which are initially loosely fitted. Comb mid-ribs or comb foundations, are suspended from profiles whose upper surfaces lie flush with the upper edge surfaces of the box, so that the top cover board is supported by the profiles. The bottom cover board and top cover board are identical to one another, being smooth on one side and having circumferential frame and a supporting plate of similar thickness on the other side thereof, such as to form a horizontal space of 8-14 mm between two mutually adjacent supers. The invention also relates to such top and bottom cover boards.
