Inserting System for Newspapers Abstract An inserter is provided for placing an insert into newspaper jackets as the jackets are fed at printing press speed. The inserts are fed from a hopper by a perforated endless continuously moving belt by means of selectively activating vacuum air pressure plenums located on the side of the belt opposite the inserts in the hopper. In one embodiment, the flow of air pressure of a vacuum to a plenum is controlled by a valve and in a second embodiment, the perforations and slots in the belt serve as the valve means. The apparatus of this invention provides rapid acceleration of inserts selectively without the necessity of overcoming the inertia of mechanical holding and feeding devices.
