Abstract
A sheet supporting arrangement comprises an upper sheet supporting grid and a lower sheet supporting grid, each made up of rods of jacks which are arranged on front and rear walls of a stacker. The upper grid consists of a series of jacks, each comprising an elastically, though not permanently deformable rod which is set at one of its ends in a piston that is also elastically, though not permanently deformable. The elastically, though not permanently rod is then guided within a bearing when it moves as well as by the circumferential surface of the piston sliding on the inner cylindrical surface of the cylinder forming the jack.
