ABSTRACT:
A first roller and its companion plate comprise structures for moving an envelope into a framework, and a second roller and its companion plate comprise structure for moving a document into the envelope, while the envelope is held open for insertion of the document. Switching devices detect the entry of the envelope and document and cause a gearing arrangement to rotate the rollers, to move the envelope to a document-receiving disposition within the framework, and to move the document into the envelope.
