According to a method of transferring a sheet through a working apparatus, a first sheet is moved by feed rolls partially into a working area of the working apparatus, which is followed by moving a second sheet by the same feed rolls to allow the leading end of the second sheet to be brought into abutment with the trailing end of its preceding first sheet and then to push the first sheet to a predetermined position within the working area. After the first sheet is thus placed and the second sheet is moved back out of the working area, the apparatus is operated to work the first sheet, for example, by pressing. The second sheet is moved forward into abutment with the trailing end of the worked first sheet and moved further while pushing the first sheet toward delivery rolls of the apparatus, which then removes the first sheet out of the working area of the apparatus. Such steps of operation is repeated to transfer a series of sheets successively through the working apparatus.
