A puncher cylinder includes a puncher knife, the cylinder being arranged for cooperation with a paper web such that the cylinder when in use can be rolled longitudinally along and in contact with the paper web, punching holes in the paper web by way of the puncher knife. The holes are punched a longitudinal distance from each other essentially corresponding to the circumference of the cylinder. A system is further disclosed including the punching cylinder, as is a method utilizing the punching cylinder, and a newspaper partly produced by way of the punching cylinder.

A corrugated box making machine has a vacuum transfer mechanism for moving corrugated boards along a path of conveyance including stations having printing and die cutter mechanisms which operate on the boards. The printing mechanisms include a print and impression cylinder, the latter being mounted in a vacuum housing that also holds drive rolls for moving the boards along the path during which the boards are held against the rolls by vacuum in the housing. The latter is movable substantially above the print cylinder to provide convenient access for maintenance of the print cylinder or replacement of its printing plates.

The invention describes a machine (10) for the in-line transformation of single-use products, comprising at least one unwinding group (12) for one or more reels (14) of web-shaped material (100), which constitutes the base support for said product, at least one printing group (18), arranged downstream of said unwinding group (12), capable of heat-printing decorative patterns, trademarks and/or inscriptions with a paraffin or natural wax-based ink (W) and/or mixtures thereof on the web-shaped material (100), and at least one folding and cutting group (20), arranged downstream of the printing group (18), wherein the printed web-shaped material (100) is folded and cut to form said products. The printing group (18) is provided with at least one melting or fluidifying group for feeding and heating the coloured waxes and paraffins (W), which need to be fluidified to be able to be applied onto the web-shaped material (100), and with one or more heating means (38; 58, 60, 62) capable of avoiding the cooling, and therefore the solidification, of the coloured waxes and paraffins (W) fed by the melting group before the waxes (W) themselves have been applied onto the web-shaped material (100).
摘要:
Systems and methods for allowing existing rotary printing press units to produce smaller pages at a faster rate of speed without having to replace the press unit. Specifically, the systems and methods relate to retrofitting an existing press unit to produce three pages of material in each full rotation instead of the traditional two pages.
摘要:
In some examples, a processing machine for processing a substrate includes at least one shaping unit and/or at least one application unit. The at least one application unit and/or the at least one shaping unit in each case includes at least one forme cylinder and at least one impression cylinder. The at least one forme cylinder of the application unit includes at least one application forme including at least one application surface and/or the at least one shaping unit includes at least one shaping tool including at least one working surface. The application surface and/or the working surface are arranged to cover at least a portion of the outer cylindrical surface of the at least one forme cylinder. A speed of the at least one forme cylinder and a speed of the at least one impression cylinder have a speed ratio with respect to one another.

The present invention relates to an inversion transfer module (60) for a converting machine having a printing module (16) comprising a first printing unit (17) arranged to print on a top side (S1) of the sheet (1), and a second printing unit (17′) arranged to print a bottom side (S2) of the sheet. The inversion transfer module is arranged between the first printing unit and the second printing unit and comprises a first inversion vacuum transfer (62) arranged to contact the first side of the sheet and a second inversion vacuum transfer (64) configured to contact the second side of the sheet, whereby the inversion transfer module is configured to change the side of adherence and transportation of the sheet.
摘要:
A device for processing substrates uses a separation system. Processed substrates can be separated into one or more waste parts and at least one blank. Improved flexibility for treating substrates is provided. The separation system comprises a transport cylinder and a stripping cylinder associated therewith. The transport cylinder has first openings and has a detachably secured packing having depressions in which perforations are formed, with at least one perforation covering at least one first opening. The stripping cylinder has a detachably secured packing having raised areas that correspond to the depressions.
摘要:
A device for treating substrates has a separation system, with which processed substrates can be separated into one or more waste parts and at least one blank. The device for treating substrates offers improved flexibility. The separation system comprises a transport cylinder and a stripping cylinder associated therewith. The transport cylinder is able to secure replaceable packing, along with first and second openings which, when the packing is secured, are covered at least partially by perforations that may be formed in the packing. A first air supply supplies air to the first openings and a second air supply supplies air to the second openings independently of the supply of the air to the first openings. The first and the second air supply are switchable between a suction air supply and a blower air supply.
