A packaging for a mattress consisting of a wrapping provided by means of a sheet of heat-sealing plastics, said wrapping comprising two rectangular portions, which are sized to cover the opposite faces of the mattress and have perimetric regions which are folded so as to cover the perimetric band of the mattress and have, along at least two mutually opposite and parallel sides of the mattress, subflaps which are folded outward and heat-sealed to each other, so as to form wings provided with slots adapted to act as handles, wherein said slots are only partially cut such that a tab remains attached inside said slots.
An apparatus for packaging a mattress with a sheet of heat-sealing plastic material unwound from at least one reel, comprising a mattress moving table which is composed of a first conveyor for the advancement of the mattress and a second conveyor for receiving the mattress, said conveyors being mutually separated by an opening, folding means for stretching a portion of said sheet of heat-sealing plastics sheet across said opening, means for actuating said conveyors to transfer said mattress from the advancement conveyor to the receiving conveyor so as to fold the sheet, by said folding means, so that said sheet covers the opposite faces of the mattress with an upper portion and a lower portion, which have perimetric regions suitable to cover the perimetric band of the mattress with flaps that are folded outward, first heat-sealing means which are actuated to join the flaps of each side that is perpendicular to the advancement direction of the mattress with two parallel heat-sealing lines, so as to close in a loop said sheet around said mattress, and second heat-sealing means for joining the two remaining flaps and forming a closed wrapping for containing said mattress, cutting means for splitting said sheet between said two parallel heat-sealing lines, and wherein punching means are provided for forming slots in the flaps of at least one side of said wrapping wherein said slots are only partially cut such that a tab remains attached inside said slots.
