ABSTRACT:
An apparatus for conveying sheets having various widths. The apparatus includes a hollow drum having a plurality of holes disposed on the outer circumferential surface thereof, a suction device for sucking air through the plurality of holes toward an interior of the drum, and a plurality of conveying belts wound on the hollow drum and adapted to be conveyed around the drum and in sliding contact therewith. The conveying belts are spaced apart from one another in the widthwise direction of the sheets so as to define gaps therebetween. Additionally, a plurality of spaced apart pressing belts are alternatingly disposed with respect to the conveying belts such that the pressing belts oppose the gaps between. In this manner, the widthwise ends of the sheets are contacted by the inside edges of a pair of conveying belts so as to convey the sheets in the proper direction.
