A web press, in particular a variable format book web press, variable format newspaper web press, or variable format periodical web press, has printing units (102a, 102b) having printing devices (109, 109a, 109b, 109c, 109d) or groups (119, 119a, 119b, 119c, 119d) of printing devices (109, 109a, 109b, 109c, 109d) for applying ink to a paper web (108). The printing devices (109, 109a, 109b, 109c, 109d) or groups (119, 119a, 119b, 119c, 119d) of printing devices (109, 109a, 109b, 109c, 109d) are constructed without rotating impression cylinders and are designed to apply ink to the paper web (108) in a noncontacting manner.
摘要:
A system for producing removable portions having personalized information, for mass-distributable packets, by single-pass manufacturing, in which a printed web is slit into two ribbons, one of which is then folded and glued upon itself to create a multi-ply ribbon that appears to be of heavier stock than the original paper, and a label containing a magnetic strip is applied. The magnetic strip can be encoded with information personalized to the recipient or the advertiser. Alternatively, the multi-ply ribbon can be created by gluing together multiple ribbons, or by a combination of folding ribbons and gluing ribbons. The multi-ply ribbon is die cut into an inside portion and an outside portion and married to the other ribbon, after which the outside portion is removed, leaving the inner portion as removable portions. Alternatively, the folded ribbon can be kiss cut after it has been married to the other ribbon. The removable portions can be coated or laminated to simulate plastic and can be printed with information personalized for the advertiser or for the recipient.
摘要:
At least one unit of a web-machinery, or a web-processing machine is pre-adjusted in a method which influences a longitudinal register. An adjustment value is derived for that at least one unit based on previously-obtained data. The adjustment value is stored in a machine control unit.
摘要:
A method and apparatus of moving printed material web includes two processing arrangements arranged one above the other that are optional in operation. A material web is processed either in the upper, first processing arrangement or in the lower, second processing arrangement. In the processing section belonging to the first processing arrangement, the material web is folded about a line parallel to its advancement direction. In the processing section belonging to the second processing arrangement, the material web is separated, along a line parallel to its advancement direction, into two material-web strands, which are then positioned one above the other. The two processing sections having in common a pair of braking rollers and a pair of drawing rollers and also a longitudinal-cutter.
摘要:
An apparatus and method for combining a plurality of printing material webs to form a multi-layer strand is disclosed. In an apparatus for combining a plurality of printing material webs to form a multi-layer strand, having a wire guide formed by deflection rolls assigned to the individual printing material webs, it is possible to achieve reliable tensioning of the former and top webs and to ensure high accuracy in that the two deflection rolls forming the outlet from the wire guide can be driven.
摘要:
A folding apparatus for folding sheets of flexible sheet materials, which includes a feeding mechanism (11, 17) for feeding sheets of material, a folding mechanism including a pair of rollers (11, 13) having a nip (23) into which a sheet of material (7) is inserted to create a fold (7b), and an inserter mechanism (21) for inserting a sheet (7) into the nip (23). The inserter mechanism (21) includes knife element (29) having an edge (31) that is arranged to engage a sheet (7) along a designated fold line (7a) and to insert said sheet (7) into the nip (23) to produce a fold (7b) along said fold line (7a). The inserter mechanism (21) is constructed and arranged to insert the sheet (7) into the nip (23) while the sheet (7) is positively engaged by the feeding mechanism (11, 17).
摘要:
Paper webs are wound up or supplied to units of a rotary printing press, such as a longitudinal fold former. Flexible endless or open ended traction devices are used. Paper webs are secured to the traction devices in a positive manner. The paper webs or their starting ends can be secured together only for purposes of being fed through the longitudinal fold former.
摘要:
The present invention concerns a method for producing an image in the edge of a volume of paper sheets. The invention can be used for numerous stationary products, note pads, exercise books, and the like. In the present invention, the images are printed not on the edges but on the paper surface. The method comprises a series of steps: printing-realigning-guillotining. The invention also concerns the insertion of a segmented image, systematically in edges and added in the make-up of a volume, for use in a complex technological process.
摘要:
Folded products are produced in a web-fed press by directing the printed web to longitudinal formers and then to multi-width transverse folders. The longitudinal formers are supported so that at least selected ones of them can be shifted vertically with respect to the transverse folders. A parallelogram-like linkage is used to shift the longitudinal formers vertically. Vertical shifting of the formers accomplishes transverse shifting of the location of the delivery of formed products from the formers to the multi-width transverse folders.
