ABSTRACT:
An apparatus and a method for successively conveying a series of sheets are disclosed. The apparatus has a first conveyer for conveying a sheet in a sheet conveying direction at a first speed and a second conveyer disposed spaced vertically away from the first conveyer for conveying the sheet in the same direction at a second speed. The second conveyer has a region overlapping with the first conveyer at least for a distance corresponding to a dimension of the sheet, e.g. the width of veneer sheet, as measured in the sheet conveying direction. A suction mechanism is disposed in said overlapping region for transferring by suction the sheet in the entirety of its dimension from the first conveyer to the second conveyer and holding by suction the sheet against the second conveyer. The sheet is further moved by the second conveyer, e.g. to a sheet stacking station.
