摘要:
A printing apparatus includes a feeding roller configured to feed a printing sheet stacked on a stacking unit, a conveyance roller configured to convey the printing sheet fed by the feeding roller, a printing unit configured to print the printing sheet conveyed by the conveyance roller, a conveyance control unit configured to control conveyance of printing sheets so that the trailing edge of a preceding sheet as a printing sheet precedingly fed from the stacking unit and the leading edge of a succeeding sheet as a printing sheet succeedingly fed from the stacking unit overlap each other, and a determination unit configured to determine whether to convey the succeeding sheet to a position facing the printing unit while keeping an overlap state between the preceding sheet and the succeeding sheet.
摘要:
A process for the production of books (22) with digital printing from signatures, in which the book comprises signature groups (33), each formed with basic sheets (34), are parts of respective signature sheets (42). The process employs a manufacturing system (21) which includes a transversal cutting equipment (41) for cutting transversally the signatures sheets, and transversal and longitudinal folding equipment (46) for the formation of respective signatures (48). For a book with at least a sheet section devoid of text and/or figures in a last signature group, the method provides: a) identify a reduced signature group (59) including a number of sheet sections having at least a page with text and/or figures; b) cut the paper strip (23) to separate the reduced signature group as reduced signature group; c) actuate the transversal folding equipment (46) limited to the sheet sections having at least a page with text and/or figures and skipping the actuation of the transversal folding equipment (46) for a single sheet section; and d) actuate the longitudinal folding equipment (47) for folding longitudinally the reduced signature group.

A process for the production of books (22) with digital printing on a continuous paper strip (23), in which the strip defines book sections in sequence, with signature groups (33), each formed with basic sheets (34); the process employs a manufacturing system (21) which includes a transversal cutting equipment (41) for separating signature groups (33) as signatures sheets, and transversal and longitudinal folding equipment (46) for the formation of respective signatures (48); for a book with at least a sheet section devoid of text and/or figures in a last signature group, the method provides: a) identify a reduced signature group (59) including a number of sheet sections having at least a page with text and/or figures; b) cut the paper strip (23) to separate the reduced signature group as reduced signature group; c) actuate the transversal folding equipment (46) limited to the sheet sections having at least a page with text and/or figures and skipping the actuation of the transversal folding equipment (46) for a single sheet section; and d) actuate the longitudinal folding equipment (47) for folding longitudinally the reduced signature group.
摘要:
A device with a gripper conveyor and with a conveying-away device as well as with means for transferring two-dimensional products fed by the gripper conveyors, to the conveying-away device amid the formation of an imbricate formation, wherein the device forms a transfer region, in which the gripper conveyor is arranged above the conveying-away device. At least two, preferably at least three product release devices which are arranged in series after one another and distanced to one another, are individually activatable and are for the individual release of the products, are assigned to the gripper conveyor in the transfer region.

An adjustable delivery web conversion apparatus is provided. The adjustable delivery web conversion apparatus includes a variable cutting apparatus cutting a printed web into a first signature and a second signature, a first assembly receiving the first signature and a second assembly downstream of the first assembly receiving the second signature. Also included are a first delivery section for receiving the first signature from the first assembly, a second delivery section for receiving the second signature from the second assembly and a stack receiving conveyor for receiving the first signature and the second signature. The first delivery section is movable between a first delivery and a first non-delivery position. The second delivery section is movable between a second delivery position and a second non-delivery position. The stacking receiving conveyor is movable between a conveying position and a non-conveying position. A method of producing and delivering signatures is also provided.
摘要:
An auto document feeding device causes an original document passing through an OUT path and an original document passing through an IN path to flow together with overlap a trailing edge of a preceding original document and a leading edge of a following original document. Before the original documents reach to a READ document glass, the auto document feeding device comprises a separating unit configured to separate an overlapping portion of the original documents. The auto document feeding device reduces a distance between the preceding original document and the following original document passing on the READ document glass to nearly 0 mm.
摘要:
A method and apparatus for the processing of print products. The method may include conveying individually the print products with a feeding device along a feeding section, transferring individually the print products from the feeding section to a further processing section, and generating control signals from a control unit. The control signals may correspond to further treatment of each individual print product and to the transfer of a print product to the further processing section such that it can be processed further. The apparatus may include a feeding device configured to convey the print products individually along a feeding section, a transfer device configured to individually transfer the print products from the feeding device to a further processing device, and a control unit configured to generate control signals to control the transfer of the print products from the feeding device to the further processing device.
摘要:
A transporting system in a packaging machine automatically merges and accumulates, usually as a shingled stream, generally flat articles having substantially continuous and discontinuous opposite sides, and includes a portion, of one of two main conveyor mechanisms, that is constructed to invert the articles, from side-to-side about endwise axes so that all of the cartons face upwardly, even though the articles of alternating groups have been inverted, during transport by that main conveyor mechanism, about their lateral axes.

A method for transporting and merging two flows of objects, in particular flat mail items, includes providing each of the two object flows with at least two respective objects. The two object flows follow one another in each respective transport path. One transport path merges into the other transport path. The two objects transported on the merging transport path are pushed over one another before reaching the merging point in such a manner that, when viewed in the transport direction, they overlap at least partially. The two objects are transported to a merging point in this overlapping state, infiltrated into the other transport path between the two objects transported on the other transport path and continue to be transported on the other transport path.

The invention relates to a method of conveying flat, flexible products, in particular printed products, and to an apparatus for implementing the method. According to the invention, the products are conveyed by means of a conveying device which comprises grippers which are moved along a movement path, grip at least one product in the region of one edge, can be controlled individually to open and close and have at least two gripper jaws, to a transfer region. There, they are deposited, at least partly overlapping one another, on a conveyor belt which is arranged substantially horizontally, runs in the conveying direction and belongs to a belt conveyor, and are conveyed away by the latter. In the transfer region, the movement path is curved and approaches the conveyor belt in the vertical direction. The products are conveyed by the conveying device in a hanging position and, in the transfer region before being deposited on the conveyor belt, are moved in such a way that the non-gripped edge of the product moves at the same path speed or a lower path speed than the gripped edge. The result, with careful handling of the products, is the implementation of an apparatus having a conveying device which requires little space.
