PURPOSE:To enable to stack cut papers in a higher speed by improving the shape of a brush from cotton to a strip. CONSTITUTION:An innumerable number of strip-shaped brushes 10 are fast fixed round a core metal 11 fitted on a brush-drive shaft 5 by a thin elastic body, for example, about 0.1mm. thick nylon cloth or the like. This construction permits to remove the axial displacement essentially and thereby prevent the turning- over of side corners of a paper 1 by a constant repelling speed against the axial direction for enabling to stack cut papers in a higher speed. |
