摘要： Successive stacks of wrapped reams of paper sheets are delivered onto first cardboard blanks on top of a first platform which is then maintained in raised position. The platform thereupon descends and the front and rear sidewalls of the blank are simultaneously pivoted against the respective sides of the descending stack before the latter leaves the first platform and continuously advances along a first horizontal path wherein the conversion of the first blank continues so that such blank ultimately constitutes a case surrounding the bottom and the sides of the respective stack. The stack is then lifted by a second platform and a second blank is placed on top of the ascending stack or even ahead of the second platform. The rising platform moves the second blank past a first set of folding devices which fold its front and rear flaps, and the stack thereupon continuously advances along a second horizontal path to complete the conversion of the second blank into a lid which overlies the top of the stack and is glued to the adjacent parts of the case. The effective width and height of the apparatus and the effective width of the hoppers for the first and second blanks are adjustable.
