Abstract
Newspapers and other printed matter fed from a printing press or inserting machine are generally folded or delivered in a continuous stream with the papers oriented in an overlapped or imbricated relationship. The stream of papers are received and stacked by the stacking apparatus or stacker which must operate at high speeds. The stacker orients the papers in the stacks and ejects the bundles of papers. The present invention relates to devices intended to reduce the prospects for inadvertent interference with the stacking mechanism or to reduce the potential for injury.
