  • Patent number: 6230383
    Abstract: The invention relates to a method for providing releasable joining together of spacers in pairs which are preferably formed by support blocks for pallets or support walls on pallets or other load carriers by joining the spacers by means of flexible straps or by means of other releasable joining means, like pins or clamps. Spacers which are unattached or which already are integral building units in a respective pallet, are fed forward by means of a hauling track compressed in pairs to a joining station after which they are joined together and clamped together tightly. The invention is also related to machines for performing the method.

  • Patent number: 4955940
    Abstract: Apparatus for carrying loads, particularly a pallet comprising spacers (2,3). Two or more pallets are interconnected by means of pairs (1,5) of spacers provided in the adjacent areas of the said pallets. Such spacer pairs, one body of which belongs to the one pallet and the other one to the other pallet, are interconnected by severable means such as a bridge and/or a shrink film and/or tapes (12) allowing a so construed multiple pallet to be produced, transported, used and stored as a unit. In operation, one pair of spacers is provided to be severed and another one held together by the said interconnectors, so that the latter forms a hinge for positioning any of the separate pallets forming a multiple pallet.
