An apparatus is provided for jogging a sheaf of papers to even up the edges in the sheaf or bundle, and includes a resiliently carried bundle compartment (1) together with means (20,21) for vibrating the compartment. The compartment comprises two substantially vertically oriented side walls (3,4), at least one end wall (5), substantially vertically oriented, and at right angles to the side walls (3,4), and a bottom (6) at right angles to said end wall (5), the compartment (1) being adapted to carry the bundle (50) with the chief surfaces thereof substantially in the vertical plane. The bottom (6) of the compartment is provided with a material (7) of high friction, such as foamed plastics, on its upper side. The vibration means (20, 21) is adapted to give the compartment a vertical vibration component as well as a horizontal vibration component which latter intersects the side wall plane of the compartment at an oblique angle. The vibratory movement is preferably shaped as a standing pear as seen in a vertical plane normal to the side wall plane. The other side wall (4) is movable towards said one side wall (4) under the influence of the vibration. |
