  • Patent number: 5092448
    Abstract: Rolls of paper are stacked in layers without any relative movement occurring between the surfaces brought into contact, using a transfer table which pivots about a horizontal axis, such that the end directed toward the wrapping machine can be swung vertically into different positions corresponding in number with the number of layers to be wrapped and matched in height with a set of tiered stacking tables, the lowest of which is also the longest; with each stacking table occupied by one layer of the paper rolls, the several layers move forward as one, in vertical alignment, to the point where the top layers run off the ends of the shorter tables together and each roll settles plumb on the roll beneath.

  • Patent number: 5081821
    Abstract: Stacks of paper sheets are transported from a sheeter into a wrapper by the upper reach of an endless infeed conveyor. The front end faces of successive stacks catch up with and are decelerated by successive flights on an endless second conveyor which is driven at a speed less than the speed of the corresponding section of the infeed conveyor. This ensures that the dimensions of so-called tails, consisting of lowermost sheets of a stack which are shifted rearwardly with reference to the sheets above them, are reduced in size or that the tails are eliminated before the stacks enter the wrapping station. Misoriented stacks are reoriented ahead of the second conveyor by two endless lead-in conveyors having flexible belts trained over vertical pulleys and defining a channel the width of which decreases in the direction of advancement of the stacks.
