Abstract:
The method of forming a book, magazine, newspaper or the like from at least first and second signatures comprises the steps of printing the first signatures and delivering the first signatures from the printing press in an overlapped shingled stream. Segments of that shingled stream are placed on a support and are releasably clamped in a stable condition on the support. The support with the signatures clamped thereon is transported and stored remote from the printing press. The signatures are then removed from storage while clamped on the support. The signatures are then unclamped and unloaded from the support and the signatures are fed in a shingled stream to a first hopper of a collating machine. The second signatures are printed and the second signatures are fed toward a second hopper of the collating machine while the first signatures are delivered to the first hopper of the collating machine, and the first and second signatures are then collated in the machine by operation thereof. Preferably, the signatures, when they are stored, are stored in a shingled relationship on the support and all folded edges of the signatures lie in one plane on the support.
Abstract:
A vertical stack of signatures is formed by first forming a dense, shingled array of signatures on a support means including first and second support surfaces oriented to define an included, obtuse angle. With the support means in a first position and the first surface extending generally horizontal, the signatures are positioned thereon in seriatim order leaning against the second surface and having one of their peripheral edges resting on the first surface. After the dense, shingled array is formed, the support means are shifted to move the dense, shingled array to a position wherein the second support means extends generally horizontally. Subsequently, a force is applied to the signatures'' peripheral edges in engagement with the first surface to shift the edges in vertical alignment relative to the second surface. Additionally, guide and stop means are provided to engage the peripheral edges opposite the edges against which the force is applied to assure the desired vertical alignment. In the particular embodiment disclosed, the dense, shingled array is formed by a pair of spaced conveyor belts from a loose, shingled stream of signatures. The belts include inclined members whhich deflect the leading edge of the signatures in an upward direction and moves them into position on the aforementioned support means.
Abstract:
An improved method and apparatus are provided for removing a densely shingled series of folded sheet material articles from a storage tray and moving the sheet material articles into a loosely shingled overlapping stream. The series of sheet material articles is transferred to a multiple of spaced-apart conveyor belts in a first conveyor assembly by moving the tray downwardly through a space between the conveyor belts. As the tray moves downwardly, the lowermost edge portions of the sheet material articles are supportingly engaged by longitudinally extending upper runs of the conveyor belts. The forwardmost article in the series of sheet material articles is held in an on-edge orientation by a plurality of sprocket wheels. As the conveyor belts advance the series of sheet material articles, the sprocket wheels are rotated to sequentially release or separate the sheet material articles. The released sheet material articles are moved to a second conveyor assembly by a transfer conveyor. The transfer conveyor is retractable from a position in which it extends between the conveyor belts of the first conveyor assembly to enable the tray to move through the space between the conveyor belts. To provide for the disposition of the sheet material articles on the second conveyor assembly in an overlapping stream, the transfer conveyor is driven at a higher speed than the first conveyor asembly and the second conveyor assembly is driven at a higher speed than the transfer conveyor.
