  • Patent number: 9963306
    Abstract: A palletizing device for a piling of layers from at least two rows of filled sacks to a sack stacking comprising a sliding device with a sliding area for the formation of a layer of filled sacks and a supply device with at least a conveyor belt for the supply of filled sacks in a feed position on the sliding area, wherein the sliding device comprises a sliding table beneath the sliding area and a slider for sliding of the filled sacks from a sliding position on the sliding area on the sliding table, wherein the conveyor belt is performed in a way that a supply distance between a feed position and the sliding position is smaller than a sliding distance between the sliding position and a frame of the sliding device at the supply edge of the conveyor belt.

  • Patent number: 7361130
    Abstract: A system for the production and subsequent palletizing of tube segments, bags, or sacks has at least one functional unit for production of tube segments, bags, or sacks, at least one device for depositing and stacking, which places and stacks the finished tube segments, bags, or sacks, and at least one storage element such as a palette, in which the stack can be deposited. The system has at least one alignment unit for the stack of the tube segments, bags, or sacks, which reduces the mutual deviations of the edges of the tube segments, bags, or sacks.
