An image forming apparatus operable with a plurality of on-line sorters each having a plurality of bins, and a control device therefor are disclosed. A first sorter and a second sorter, for example, are linked to a stencil printer in an online configuration. A sorter to be used can be freely selected or can be automatically selected by the control device. A sorter link mode key is pressed in a particular manner to select one of a first sorfer priority mode, second sorter priority mode, first sorter only mode, and second sorter only mode. One of the first and second sorters is selected on the basis of the mode selected on the sorter link mode key.

Product delivery system for a printing-press folder having a cutting unit for dividing printed webs of material into a multiplicity of printed copies or signatures, and a gripper cylinder includes a device for alternatively feeding cross-folded copies from the gripper cylinder to a device for producing a second longitudinal fold and to delivery units disposed down-line therefrom, on the one hand, and to a further chargeable delivery unit for cross-folded copies, on the other hand, the copy delivery units being chargeable facultatively in accordance with a respective production mode, the alternative feeding device including a first conveyor surface formed of delivery belts encompassing a 90.degree.-turn, a second conveyor surface disposed within the folder and formed of a conveyor belt, and a swivelable diverter for selectively delivering copies alternatively onto the first conveyor surface and onto the second conveyor surface, the swivelable diverter being connectible with a stacker.

To transport, store, process and handle and distribute a plurality of printed products, retained in cassettes on a minimum of space, the cassettes are vertically stored, preferably in pairs. Transport can occur in a predetermined plane, of full and empty cassettes, respectively, the cassettes being moved within the storage elements by horizontal and vertical or lift transport elements, so that the cassettes can be moved in all directions of the three-dimensional storage structures and removed from any one position. The cassettes can be loaded on carts or carriages and coupled together to be moved in form of trains by a drive head (28) past product delivery stations, such as folding apparatus (9, 13) coupled to printing machine units (1-8), for placement in the storage racks; and removed from the cassettes, collected in groups in pivotable holders (116-119), with two, each, holders facing each other and pivoting towards each other so that the groups of products in the holders will be cross-positioned on the delivery or removal apparatus, for example a transport belt (124).

A folder apparatus is disclosed which is adapted for use with at least two adjacently arriving webs and having at least one fan wheel. The fan wheel is provided with a number of compartments delimited by guide disks to ensure, that in the case of different processing of the two or more webs, that all of the compartments therefor are used. The fan wheel of the folding apparatus is divided up into a number of laterally adjoining fan wheel sections, which number corresponds to the number of webs to be handled and able to be driven separately from each other by associated drive means.

In a printing machine, a sheet delivery device having pneumatic braking devices of substantially bipartite construction on a chain delivery arranged as rotating brake rollers on a traverse extending beneath the chain delivery transversely to a sheet conveying direction through the printing machine and upstream of a sheet pile, as viewed in the sheet conveying direction, for braking and drawing-out a sheet exiting from the printing maching includes separate suction units with suction air feeding devices operatively associated with the brake rollers for feeding suction air to lateral faces of the brake rollers, at least one of the suction units being selectively associated operatively with at least one lateral face of each of the brake rollers, each of the brake rollers having a sheet-carrying peripheral surface formed with recesses distributed over the periphery of the respective brake roller and extending over a region of the width of the respective brake roller encompassing a lateral edge of the sheet-carrying peripheral surface and disposed in a radially outer region of the one lateral face of the respective brake roller, the suction units being formed with lateral air outlet openings located at a respective radially outer segment region of the one lateral face of the respective brake roller.
摘要:
The printed products arriving in an imbricated formation are wound up into wound product packages or coils each having a substantially horizontally disposed longitudinal axis. These wound products packages possess a predetermined size and an inherent stability which permit them to be transported and intermediately stored such that their longitudinal axes extend substantially vertically without the wound product packages disintegrating or unraveling. After forming the wound product packages they are transferred from a standing position into a reclining or reposing position by means of a package turning device. In this reclining or reposing position the longitudinal axes of the wound product packages extend substantially vertically. These wound product packages are supported only at their circumference or are only held at their winding cores and are not supported in any further manner.
摘要:
An improved printing press. The printing press forms transverse lines of weakening at spaced intervals along a continuous strip of paper after the paper has been imprinted with a repeating business format. The press then creases the strip of paper along the lines of weakening formed therein.

A stacking device having at least two stacking wells supplied from above is arranged subsequent to a delivery conveyor for printed products. A deposition apparatus for depositing one cover sheet on each completed stack is also provided. In order not to have to deposit this cover sheet upon the stack just as it leaves the stacking device, a device for preparing individual pre-printed cover sheets is provided. The deposition apparatus includes a cover sheet conveyor arranged subsequent to this cover sheet preparing device. The cover sheet conveyor is provided with a controllable outlet for each stacking well and opens into its associated stacking well.
摘要:
A sheet feeding unit includes a stack elevator which raises the top of a supported stack of sheets to infeed height. A sensor senses the position of the top sheets of the stack, to ascertain whether these exhibit improper left or right offset. Depending upon the magnitude and size of the sensed offset, the stack elevator is correctively shifted, to minimize offset at the top of the stack. Although the sensor is located to only one side of the stack, not at both sides of the stack, it is capable of sensing offset in both left and right directions. When the elevator is lowered, for the laying in of a fresh stack, it is automatically brought to a centered position.
