Abstract: A method and apparatus for horizontal stacking of sheets or signatures received from a web press or the like includes conveyor sections operative to convey the sheets in shingled relation from a generally horizontal conveyor path to an inclined conveyor section that progressively rotates the sheets to inclined positions such that the sheets slide downward against an edge guide. The inclined sheets then pass upwardly through a loop conveyor section at an inclined angle to vertical. The upper edge of each success sheet engages a stop mechanism after which the sheets move horizontally into a generally V-shaped trough that engages and supports two downwardly facing edges of each sheet.

Abstract: An arrangement for decelerating and shingling printed products as they are conveyed from a variable rotary cutter by a high-speed belt conveyor to a slower speed belt conveyor includes at least one depressor wheel at the entry end of the slower speed conveyor. The depressor wheel carries a plurality of depressor members in circumferential positions corresponding to the circumferential positions of cutting knives on the rotary cutter. The leading edge of each printed product entering the slow speed conveyor enters a headstop nip which reduces the speed of the entering product while its trailing edge is simultaneously momentarily depressed by a depressor on the rotating depressor wheel to enable shingling between successive products. A brake pad cooperates with the depressors to decelerate the printed products to a speed close to the surface speed of the slower belt conveyor.

Abstract: A variable rotary cutter assembly for transverse cutting of web material as it passes between rotating anvil and knife cylinders includes one or more cutter assemblies selectively positionable on the periphery of the knife cylinder. Various embodiments of the cutter assembly include a pair of pivotally connected block members adapted for releasable mounting on the knife cylinder and carrying an elongated knife blade which is biased outwardly by spring means about a pivot axis parallel to and spaced from the knife blade. The spring means enable a precise predetermined cutting pressure per unit length of the knife blade to be established against the anvil cylinder while enabling self-adjusting movement of the knife blade to accommodate substantial variance in anvil and knife cylinder spacing and knife blade wear. The cutter assemblies may be mounted to effect single or double transverse web cuts, and stripper means are provided to remove trim strips cut from the web by pairs of knife blades.

Abstract: A variable rotary cutter assembly for transverse cutting of web material as it passes through a nip between rotating anvil and knife cylinders includes one or more cutter assemblies selectively positionable on the periphery of the knife cylinder. Each cutter assembly includes a base block adapted to be releasibly mounted on the knife cylinder, and a pair of pivotally connected block members one of which is adapted for releasibly mounting on an associated base block and the other of which carries an elongated knife blade and is outwardly pivotable about a pivot axis parallel to and spaced from the knife blade. Spring means bias the knife carrier block member outwardly about its pivot axis so as to effect a predetermined cutting pressure per unit length of the knife blade against the anvil while enabling self-adjusting movement of the knife blade to accommodate substantial variance in anvil and knife cylinder spacing and knife blade wear.

Abstract: A liquid applicator machine of the type operative to apply a liquid such as glue to a moving paper web or the like through a high speed transfer roll which receives a metered film layer of liquid thereon from a pan roller. A static ring is supported in coaxial predetermined spaced relation to each end edge surface of the transfer roll and has an outer annular surface overlapped by the pan roller such that liquid carried upwardly by the end surfaces of the pan roller engages the static ring and is prevented from accumulating at the end edges of the transfer roll and being slung therefrom during high speed rotation of the transfer roll. The invention finds application with full width and segmented transfer rolls to prevent fluid slinging therefrom.

Abstract: Apparatus for use in folding web material includes a plow folder supported intermediate transverse entrance and exit rollers and cooperative therewith to effect longitudinal folding of the web as it moves longitudinally through the apparatus. In a preferred embodiment, the plow folder includes at least one rotatable cylindrical web engaging roller and a fold forming member coaxial with the web engaging roller and having a partial cylindrical outer peripheral surface and an axially outwardly facing fold surface subtending an acute angle with the longitudinal axis of the fold forming member. Air orifices are formed in the outer peripheral surface of the fold forming member to facilitate air lubrication between the fold forming member and the moving web.
