Abstract
Device for feeding and further processing printing material in sheet-fed rotary printing presses includes a paper storage having a roller pair for conveying sheets out of the paper storage and a feed table movable relative to the paper storage. An optical detection device for detecting mis-fed sheets is disposed in the paper storage behind the roller pair and forward of the feed table. A transport roller and an intermediate gear wheel for driving the transport roller are mounted in the feed table. A device is disposed in the feed table for removing mis-fed sheets, and includes a shaft, at least two remover rollers rotatably mounted on the shaft, and an upper guide plate and a lower guide plate disposed adjacent the remover rollers. The guide plates, respectively, are formed with recesses and define therebetween a travel path for the sheets. The remover rollers dip into the recesses, and are cooperatively associated with the transport roller for removing mis-fed sheets.
