Abstract:
Imaging apparatus and methods for bindery systems are disclosed. An example apparatus includes a platform and a separator coupled to the platform. The separator to receive a signature assembly, the separator includes an end to engage the signature assembly to separate a first page from the signature assembly, a first guide to direct the first page toward the platform and a second guide to direct a second page of the signature assembly toward a side of the platform. The apparatus includes a printer positioned above the platform. The printer is to image the first page when the first page is disposed on the platform. The apparatus includes a pump fluidly coupled through the platform to draw the first page toward the platform.
Abstract:
A method for controlling a feeder of a gathering-stitching machine reduces the operating effort when setting the feeder, increases reliability when laying folded sheets on a transport device and improves quality during collating and stitching. Opening and closing times of grippers are regulated under program control, continuously and as a function of format when controlling the feeder of the gathering-stitching machine. Data relating to the dimensions and to the number of pages of the folded sheets is thus entered into a control device, from which data actuating signals for actuating elements of the grippers are generated.
Abstract:
With a method for operating a transport system, used in the production of printed products composed of signatures or printed sheets, at least one first conveying belt is provided downstream of a printing press designed for producing the signatures or printed sheets. Further downstream, this conveying belt is divided into at least two individually operating conveying paths, wherein at the end of each of the conveying paths the transported signatures or printed sheets are supplied while positioned straddling and via a continuously operating folding device to at least one intermediate gathering device. For the further transport, the signatures or printed sheets are transferred from the gathering device in a serial, monotonous, intermittent, synchronous or non-synchronous sequence to a main conveying section. The signatures or printed sheets which are combined to form partial book blocks or complete book blocks are then wire-stapled, thread-stitched or bound with adhesive.
Abstract:
A rotary blade device for interacting with printed materials has a rotating arm, a first pulley rotatably supported on the rotating arm, a first blade fixed to the first pulley, a fixed pulley, and a first belt connecting the first pulley to the fixed pulley so that as the arm rotates, the first pulley rotates with respect to the arm.
Abstract:
The folding, and accumulation in configurations simulating a booklet, of flexible sheets (such as paper sheets) is accomplished in a simple, straight-forward, yet effective manner. A movable bar is pivotally mounted at a first end adjacent a cutter from which it receives paper sheets. A plurality of first pulleys having a circumferential periphery with a concave substantially V-shape are mounted by the movable bar and cooperate with a second plurality of pulleys on a stationary V-shaped bar. The second pulleys have convex substantially V-shaped circumferential peripheries with a groove for receipt of a circular cross-section conveyor belt which extends between the sets of pulleys and drives sheets for folding between them. At the discharge end of the folder is a downwardly sloping convex substantially V-shaped accumulator bar which cooperates with a guide (having a concave V-shape) and an automatically movable stop. After a plurality of folded paper sheets in a configuration simulating a booklet are collected, the stop is released and they are transmitted to a binder.
Abstract:
A method and apparatus of in-line die-cutting in saddle signature gathering wherein signature sets are gathered on a gathering chain to form signature sets. The signature set is grasped by a pair of belts which lift the signature off the gathering line so that a portion of the signature set along the spine thereof may be removed by a die-cutting pair of plates located above the gathering line. The signature sets may be stopped as lifting and cutting occurs. After lifting and cutting the signature set is replaced on the gathering line for further processing.
Abstract:
Collation of folded printed signatures or sheets is accomplished by a rotating collating cylinder or rotary collator which is rotatably driven about its longitudinal axis of revolution. The rotary collator comprises a plurality of collating conveyors arranged substantially parallel to this longitudinal axis. These collating conveyors are substantially annularly positioned about this longitudinal axis and extend substantially parallel to the longitudinal axis of the rotary collator. The folded printed signatures or sheets are fed or conveyed by three feeding conveyors or infeed devices and are deposited to straddle the collating conveyors or the respective folded printed signatures or sheets already straddling the collating conveyors. The folded printed signatures or sheets are displaced in the direction of conveyance of the rotary collator while revolving about the longitudinal axis of the rotary collator. The printed signatures or sheets are thus conveyed along a path which has the shape of a helix or coiled spiral. The end products are gripped at a product withdrawal location by a withdrawal conveyor or device and conveyed to a different location.
Abstract:
A copier capable of binding copy papers at their center or their edge as desired. A bookbinding device is operatively connected to a paper outlet of the copier. To bind the papers at their center, a folding mechanism of the bookbinding device is activated first in order to form a crease along the center of each copy paper. Then, a binding mechanism of the bookbinding device is activated to sequentially stack the papers in an upwardly convex form and such that the creases face upward in alignment and, then, stich the papers together along the aligned creases by means of a stapler or the like. The bound papers are discharged to a stacking mechanism of the bookbinding device in a developed position so as to be stacked there while being folded double in the creases.
Abstract:
An improved apparatus for feeding signatures from a saddle to a trimmer mechanism includes a transfer apparatus which moves each signature in turn from the saddle onto a conveyor assembly at a delivery station. The conveyor assembly includes a plurality of chains having pusher fingers which engage the trailing edges of the signatures. The pusher fingers move the signatures into the trimmer mechanism. The pusher fingers on the conveyor assembly are registered relative to a stop in the trimmer mechanism to at least partially register the signatures before they enter the trimmer mechanism. The transfer assembly, which moves the signatures from the saddle to the conveyor assembly, is effective to positively grip each signature in turn by applying a clamping force to opposite sides of the signature. These clamping forces are continuously applied to the signature from the time it leaves the saddle until it is deposited on the conveyor assembly where it is engaged by the pusher fingers. This prevents twisting and jamming of the signatures in the transfer assembly and/or at the entrance to the conveyor assembly.
Abstract:
A pair of endless parallel conveying chains have respective upper horizontal runs on which paper sheets are to be conveyed towards a discharge location. Engaging elements are provided equi-distantly spaced on the chains and are each mounted for pivotal displacement between two end positions in one of which they extend into and in the other of which they are retracted out of the path of movement of objects on the runs. Appropriate guides effect pivoting of the engaging elements to the other position in which they are retracted out of the path of movement of objects, when the engaging elements arrive at the discharge location.
