This device has at least one web processing tool which is configured as a fold former, and one web processing tool that is configured as a cutting blade and which is situated upstream from the fold former in the web path. The cutting blade and the fold former can be moved crosswise to the direction of travel of the material web via at least one actuator. The cutting blade is configured as the cutting blade of a longitudinal cutting device, which is situated upstream from the fold former, and is provided with a lateral drive that is mechanically separate from a drive of the fold former. The longitudinal cutting device has at least two cutting blades that are spaced apart from one another crosswise to the direction of web travel. These at least two cutting blades can be moved crosswise to the web travel direction, but each in a direction that is opposite from the other via a shared drive. The drive for the fold former and the drive of the cutting blade are in functional active connection with one another through a shared control device. The functional active connection is preferably structured such that the two drives can be regulated in a shared work process, especially during an adjustment process, by way of a program sequence. The control device is preferably configured to determine a suitable target position for the respective cutting blade from data on the web width and/or a planned web path, and to the respective drive to arrive at this suitable target position.
A method for producing a newspaper is known from WO 99/30909 A1. In a web-fed rotary printing press, a plurality of material webs or of partial material webs are guided one over another. Prior to the accomplishment of a crosswise cutting of a partial web of material, perforations are formed in the partial material web. At least one part of the now perforated partial web, that is connected, in terms of content, to the rest of the partial web, such as, for example, a block of information, is delimited by these perforations. Additionally, at least one column of the partial web is delimited by perforations that extend continuously over the entire height of a page.
U.S. Pat. No. 4,685,699 A describes a sheet, which is provided with perforations and that is intended for insertion in a newspaper. The sheet is intended to be provided with removable coupons.
A publication with removable cards is known from U.S. Pat. No. 3,930,700 A. The cards may be separated by the use of perforations.
Frequently, a perforated line, which has been generated in a page of a printed product, is difficult for a reader to detect due to its fine cross-section. This makes it difficult to separate the perforated portion of the page from the rest of the page, along the perforated line because of the reader's difficulty in detection of the line of perforation.
The object of the present invention is to create a page of a printed product having a plurality of information fields which are arranged in different printed columns. In accordance with the present invention, a position of a perforated line generated in the page can be easily detected by a person who is viewing the page. Additionally, in accordance with the present invention, a longitudinal perforation device is provided, which longitudinal perforation device is suitable for producing this printed product with the perforated page. The location of the longitudinal perforation device, in the web-fed rotary printing press, can be easily exchanged.
The objects of the present invention are attained, according to the present invention, with the provision of a pictogram on the printed page and which extends on both sides of the perforated line. The pictogram makes the line of perforation much more visible. The longitudinal perforation device is configured as a module that is independent of the web-fed rotary printing press. Such a module can be used in different places in the same web-fed rotary printing press or can be used at different times in different web-fed rotary printing presses.
The benefits to be achieved with the present invention consist especially in that by using the proposed longitudinal perforation device, a printed product can be produced. At least one page of such a printed product, in which a perforated line that would otherwise by difficult to detect, is visualized. To aid in such visualization of the perforated line, the pictogram, which has -been applied to the page, also encourages the viewer to actually perform a separation process along such a perforated line. The pictogram can be implemented along the perforated line. It is particularly advantageous, in accordance with the present invention, for the pictogram to depict a motif that is associated with an information field in the printed column, which is to be separated along the perforated line. With this cooperation of pictogram and information field, a particular promotional function can be assigned to the pictogram, in combination with the information field to be separated. The pictogram thereby increases, for example, the promotional function which is intended to be accomplished by an information field, thus giving the pictogram a multi-purpose function. A pictogram, as used in this context, is an image with a motif that is visually similar to a tangible object, so that the viewer will associate concrete informational content with the pictogram. The new advertising form which is described here can contribute to producing the desired interactivity between advertiser and newspaper reader without requiring, for example, the placement of post-it notes, and without spending the additional time and expense that such a manual operation requires in the shipping department. The present invention thus increases the rate of response to current notices by commercial or other clients.
The longitudinal perforation device, in accordance with the present invention, which may be used in producing this printed product, has the advantage of being configured as an autonomous module, which, by virtue of its simple installation and the resultant associated short set-up time, can be flexibly used in one, or even in multiple web-fed rotary printing presses. Advantageously, a position of a perforating blade, which is utilized in this longitudinal perforation device, and which is adjusted transversely to a direction of travel of the web of printing substrate, can be altered, without risk, by a person who is operating the web-fed rotary printing press and while the web-fed rotary printing press is in operation. In a further embodiment of the present invention, the position of the perforating blade can also be automatically reset in order to maintain a predetermined, fixed correlation of the perforating blade and thus of the resultant line of perforation to the relevant printed image. With the longitudinal perforation device, in accordance with the present invention, for example, a newspaper can be produced, which has at least one newspaper page with a section that can be separated cleanly along the height of that newspaper page without the need for, or the use of auxiliary devices. The perforated line that can be produced using the longitudinal perforation device always extends over the entire height of the newspaper page. However, it can be variably positioned across the width of such a newspaper page.
A preferred embodiment of the present invention is depicted in the set of drawings, and will be described in greater detail in what follows.
The drawings show in:
Referring initially to
Between the two printed columns 03; 04, which are arranged side-by-side on the same side 02 of the page 01, as seen in
At least one printed column 03; 04, together with its at least one information field 06; 07; 08; 09; 11, can be easily completely separated from the remaining part of the page 01, along a single perforated line 13, in a separation process to be performed without auxiliary devices. In the example which is shown schematically in
The pictogram 16, that extends on both sides of the perforated line 13, also extends over at least a section of the perforated line 13 that is to be used for the separation process. In accordance with the present invention, it can also be provided that a pictogram 16 is situated along the perforated line 13 in each of a plurality of sections of the perforated line 13, and with a plurality of individual pictograms 16, preferably each with the same motif, being arranged along the perforated line 13. In an alternative embodiment, a plurality of individual pictograms 16, with different individual motifs, can also be arranged along the same perforated line 13. Regardless of whether one or more pictograms 16 are arranged along the same perforated line 13, a length 116 of the respective pictogram 16, which, in any case extends along a section of the perforated line 13, extends over at least 20% of the height h12 of the type area 12, and preferably extends over at least 50% of the height h12 of the type area 12. The length 116 of the pictogram 16 that extends along a section of the perforated line 13 is preferably formed over at least 70% of the height h12 of the type area 12. Pictogram 16 can also extend over the entire height h12 of the type area 12, as is shown in the example depicted in
The information fields 06; 07; 08; 09; 11, which are typically arranged in printed columns 03; 04, and which are intended to be separated from one another, each have a section length 106; 07; 108; 09; 111, which is oriented parallel to the perforated line 13 to be used for accomplishment of the separation process. It is preferable that the length 116 of the pictogram 16 that extends along a section of the perforated line 13 corresponds at least to the section length 106; 07; 108; 09; 111 of one of the information fields 06; 07; 08; 09; 11 that are arranged in the printed columns 03;, 04 to be separated from one another. In the example shown in
The printed product is preferably produced using a web-type printing substrate, such as, for example, a material web, and especially a paper web. The printed product can have a plurality of pages 01, which can, for example, also be attached to one another, such as, for example, via a form closure or an adhesive closure. The perforated line 13 to be used for the above-described separation process is generated in the page 01, such as, for example, by using either a perforating blade 22, which is situated in the superstructure of a printing press, as depicted in
The page 01 is preferably printed on both sides or faces, such as, for example, on its front and its reverse sides or faces 02. The configuration of the printed columns 03; 04 printed on the front side and on the reverse side 02 is preferably coordinated such that the perforated line 13 extends, on both the front side and the reverse side 02 of the page 01 between two printed columns 03; 04, each containing at least one information field 06; 07; 08; 09; 11. The position of the perforated line 13 is then preferably visualized on both the front side 02 and also on the reverse side 02 of the page 01, in each case, by at least one pictogram 16, and preferably is visualized on both sides 02 by the same pictogram 16. The printed columns 03; 04, which are situated on the front side and reverse side 02 of page 1 and which are to be separated along the same perforated line 13, preferably each have at least one information field 06; 07; 08; 09; 11, with these fields being related to one another in terms of content. For example, they can contain advertisements from the same firm. A large format advertisement can also be situated on the front side 02 of page 01, for example, with a coupon or a contact address for the firm advertising on the front side 02 being arranged on the reverse side 02 of page 01.
A longitudinal perforation device 21 for use with a printing press, such as, for example, a web-fed rotary printing press, and having at least one perforating blade 22, will now be described, with reference to
As is illustrated in the perspective representation depicted in
Each of the two guide elements 23; 24 has a support 26; 27, which can be adjusted in an axial direction of the respective guide element 23; 24, preferably by shifting it along its respective guide element. One of the supports 26 supports the perforating blade 22, which is rotatably mounted in a bearing assembly, as a so-called fly blade 22. The other support 27 supports a cutting ring 28, also mounted in a rotatable bearing, and adapted to function as a bed blade 28. The perforating blade 22 and the cutting ring 28 are positioned-on their respective guide elements 23; 24 in such a way that they interact with each other to form a perforated line 13 to be generated in the web of printing substrate in its direction of travel. The perforating blade 22 and the cutting ring 28 are thus engaged against one another to form the perforated line 13 which, as depicted in
Each of the supports 26; 27, which are non-rotatably guided for axial movement on the respective guide elements 23; 24, such as, for example, by being in engagement with a groove formed in the guide, is coupled with an actuating drive 31; 32. Each of the two actuating drives 31; 32 for the respective supports 26; 27 is configured, for example, as a threaded spindle 31; 32 which is arranged parallel to the longitudinal axis of its respective guide element 23; 24. Each support 26; 27 is adjusted, in terms of its respective axial position, by a rotational movement of the allocated threaded spindle 31; 32 and is thus caused to shift axially along the respective guide element 23; 24. The adjustment of each support 26; 27 is implemented using an adjustment device 41, which is an integral part of the longitudinal perforation device 21 and which preferably is capable of positioning both supports 26; 27 in the same adjustment process. This adjustment device 41 can be actuated manually, such as, for example, by use of a hand wheel 29, or can be actuated automatically. For instance, the adjustment device 41 can also be remotely controlled, especially from a control center, which is not specifically depicted, and that is a part of the web-fed rotary printing press. The hand wheel 29 is preferably located outside of the area of the longitudinal perforation device 21 that guides the web of printing substrate. Accordingly, so that a person operating the web-fed rotary printing press can actuate this hand wheel 29 without risk, even if the web-fed rotary printing press is in operation. The axial position of at least the perforating blade 22 can be reset when a production operation is underway, even by way of a manual adjustment.
Each support 26; 27 preferably includes a pivotable lever 33; 34, respectively, to which lever 33, 34 the perforating blade 22 or the cutting ring 28, respectively, is attached. As may be seen in
The two spaced, parallel guide elements 23; 24, preferably along with their respective, connected actuating drives 31; 32, are attached to a shared base plate 36 on at least one of their respective end surfaces, as is depicted in
The longitudinal perforation device 21 can, if desired or if necessary, such as for reasons of web width, be attached, in the direction of travel of the web of printing substrate, at both sides of the web-fed rotary printing press, and if necessary can even be mounted overhead above the path of web travel through the rotary printing press.
The base plate 36 for the longitudinal perforation device, which preferably also supports the adjustment device 41 for use in the positioning of the respective supports 26; 27, along with each support's respective one of the perforating blade 22 or the cutting ring 28, can preferably be mounted on the web-fed rotary printing press, separably and/or only temporarily, using a small number of connecting elements 37. As depicted in
The longitudinal perforation device 21 is preferably situated in a respective web-fed rotary printing press in the direction of travel of a web of printing substrate, preferably upstream from a fold former of the web-fed rotary printing press. The fold former can be adjusted, for example, in its position crosswise to the direction of travel of the web of printing substrate. The at least one perforating blade 22 of the longitudinal perforation device 21 can be adjusted, in respect to its position crosswise to the direction of travel of the web of printing substrate, independently of at least the position of the fold former, which fold former can also be shifted crosswise to the direction of travel of the web of printing substrate. In addition, the adjustment device 41, which is usable to adjust the position of the at least one perforating blade 22 crosswise with respect to the direction of travel of the web of printing substrate, is separate at least from an adjustment device used to adjust the fold former crosswise to the direction of travel of the web of printing substrate. A web of printing substrate which has passed through the longitudinal perforation device:21 and which is thus provided with the perforated line 13, then passes over the fold former, which is not specifically shown.
The adjustment device 41 preferably has a display device 42, such as, for example, a scale 42 that indicates a dimensional property, through the use of which, a position of the perforating blade 22 can be clearly quantified or verified. The center of the fold former, for example, can serve as a reference for the dimensional property displayed on the scale 42. The position of the at least one perforating blade 22 can thus be adjusted, relative to the center of the fold former. A dimensional property displayed on the scale 42 can then be interpreted as a distance measurement which is oriented crosswise to the direction of travel of the web of printing substrate, relative to the center of the fold former. Another variation provides that an edge 14 of the web of printing substrate being guided between the guide elements 23; 24, as seen in
The position of the perforating blade 22 is advantageously determined using data, which data has preferably been electronically stored in a computer unit, and which data was generated on a prepress that is to precede the printing process to be performed using the web-fed rotary printing press. This data determines the position of the print image to be imprinted on the printing substrate, and, from the use of a fixed correlation between the print image and the perforated line 13 that must be maintained, determines the position or orientation of the perforated line 13. Using this data, the distance measurement, such as, for example, of the edge 14 of the web of printing substrate from the position of the perforating blade 22, which is adjusted using the adjustment device 41, is adjusted. The adjustment device 41 performs the adjustment of the distance measurement automatically, such as, for example, through program control.
While preferred embodiments of a page of a printed product having a plurality of information fields arranged in different print columns, and a longitudinal perforation device for providing the page, in accordance with the present invention, have been set forth fully and completely hereinabove, it will be apparent to one of skill in the art that various changes in, for example, the type of printing press used, the drives for the printing cylinders and the like could be made without departing from the true spirit and scope of the present invention which is accordingly to be limited only by the appended claims.
