ABSTRACT:
A method and apparatus for conveying and staggering envelope contents includes a driven, substantially vertically positioned conveyor belt with an associated conveying slit, through which the envelope contents including documents to be staggered, are moved past an operator. On the side of the envelope contents opposite the conveyor belt (i.e., facing the operator) there is a non-rotary or slowly rotatable delay roller which can be pressed against the document facing it. The delay roller is preferably moved by an electromagnet. The friction between the delay roller and the document facing it is much greater than the friction between the two envelope contents, so that the front document facing the delay roller is decelerated, while the back document is advanced by the conveyor belt until the two documents are staggered. The operator can then detect whether or not there is a document behind the front document, and whether it is correctly oriented. A second, parallel conveying slit with conveyor belt can be provided behind the first conveying slit for the opened and emptied envelopes.
