Abstract: Rotary printing presses of the type embodying rotatably driven series of inking cylinder, plate cylinder and impression cylinder components. Particularly, a mechanism for "bumping" the impression cylinder shaft with respect to the plate cylinder for press adjustment or repair and web adjustment without dismantling of the press. The "bumping" mechanism includes eccentric bushing plates supporting the impression cylinder shaft at either end and a pivotally mounted bell crank with a follower strut pivotally secured to the bushing plate. As the bell crank is pivoted, the impression cylinder shaft is "bumped" or displaced with respect to the plate cylinder.

Abstract: An improved high speed in-line inserting method and apparatus which allows a modular construction and greater simplicity due to reliance on mechanical supporting and gripping procedures. Folded newspapers or other signatures are carried rectilinearly along an endless belt and supported within a pivotable frame and affixed frame. The pivotable frame and the fixed frame are provided on their distal ends with mechanical cam actuated gripping means to positively open a newspaper which includes a folded lap on its top half so that an insert may be impelled into a forwarded and upwardly opening pocket. The thusly formed composite newspaper is then advantageously discharged onto a self shingling endless belt below the first endless carrier belt. Inserts for impelling into the signature or folded newspaper are advantageously disclosed to be fed from a feeder hopper which includes a vibrating end plate and a bottommost feed through a suction pick-up and nipper rolling procedure.

Abstract: Apparatus and method for high speed in-line paper inserting, primarily for insertion of supplements and the like into newspapers, wherein newspaper jackets and inserts are advanced and manipulated in a straight line motion. The system includes means for rectilinearly conveying a folded newspaper jacket and placement thereof in a pocket, where the jacket is opened by an edge gripping mechanism, and an insert is impelled into the so opened jacket at a higher speed than that of the advancing jacket, the jacket then being released by the gripping mechanism to close with the insert therein, and the assembled newspaper, including insert, is then removed from the jacket for further conveying and processing. The insert pick-up station being of an improved advanced design to so improve pick-up and advancement of the insert.
