Method for stacking of filled sacks to a pallet-free sack stacking

Method for stacking of filled sacks to a pallet-free sack stack comprising the following:

• Forming of a first layer from at least two rows of filled sacks,
• Forming of at least one further layer from at least two rows of filled sacks on top of the first layer, and
• Covering of the completed sack stack with at least a stabilizing cover,
• wherein
• the first layer or a last layer of the sack stack comprise at least two recesses formed to engage a forklift for elevation, and a stiff intermediate insert is inserted between said at least two recesses and a layer neighboring said recesses in said sack stack, said stiff intermediate insert comprising one member selected from the group consisting of paper, corrugated cardboard carton and plastic, said stiff intermediate insert consisting of a floor space, a first lateral flap and a second lateral flap, said stiff intermediate insert has a fold to provide the first lateral flap, the first lateral flap having a length and a height, the length being a principle direction of extension, said length and said fold being along a first lateral side of the sacks of one of two neighboring ones of said layers and transverse to a fork insert direction of the at least two recesses, the first lateral side being the side of the stack into which fork insertion is carried out, the height being equal to a height of one layer of said filled stacks, the first lateral flap providing a one of said sacks directly over one of said recesses with support perpendicular to an axis of said fork insert direction, said first lateral flap additionally providing support against outward deformation of said sack along said fork insert direction, the method further comprising providing the second lateral flap by folding said stiff intermediate insert on a second, opposing, lateral side of said stack, the first and second lateral flaps thereby providing stiffening to said stiff intermediate insert to support said stack for said elevation.
