Abstract
A sheet inserter inserts special insert sheets into a continuous stream of sheets by overlaying the insert sheets with a corresponding sheet in the continuous stream of sheets. The insert sheet overlaying the corresponding sheet in the continuous stream of sheets is then conveyed with the corresponding sheet to a final destination where the sheets can be compiled into a stack. The sheet inserter can be contained in a module which is removably attachable to a document finishing apparatus so as to insert the special insert sheets into the stream of sheets that are output from the document producing apparatus. When the document producing apparatus is associated with a finishing device such as a booklet maker, which compiles and stitches multiple copies of a booklet, the sheet inserter inserts one or more special insert sheets at the appropriate location(s) for each booklet as the sheets are entering the assembly station of the booklet maker. The special insert sheets can be cover sheets and/or center sheets for each booklet, and/or sheets to be inserted at other locations in each booklet.
