The invention is in the field of the further processing of printed products and pertains to a covering sheet according to the introductory portion of the first independent claim. The main function of the covering sheet is to bring together the printed product, which is, in particular, a newspaper or magazine with diverse supplements (e.g. further newspapers or magazines, prospectuses, brochures, CDs or other data carriers, sample objects) to form a unit, which is suitable for distribution, i.e. simple to handle. The invention additionally pertains to a method for wrapping newspapers or magazines by means of covering sheets.
The individual wrapping for distribution in particular of magazines possibly with supplements by means of an at least partly transparent plastic film and to seal the film around the newspaper is known. Thus a magazine ready for distribution is created, which is firstly protected from outside influences, in particular moisture and secondly guarantees that the magazine stays in new condition, which thirdly due to its transparency maintains the visibility of the magazine including promotional printing on its outside and which fourthly combines the magazine and supplements, which are inserted into or loosely added to the magazine to form a more or less stable and simply handlable unit. Printed products wrapped in this manner have become widely established, particularly where they are distributed by mail and are increasingly common, where the reader purchases them directly form the distributor (e.g. newsstand). It has also been suggested to offer daily newspapers wrapped in the named manner.
The named transparent plastic wrapping on the other hand has the disadvantage that it, as soon as the printed product has reached the reader, must be disposed of as waste and that the wrapping, by enclosure in plastic foil and sealing, is extremely time- and space-consuming. As known devices for wrapping normally have very restricted capacity, it is necessary to provide a plurality of wrapping devices operating in parallel for the on-line processing of e.g. the products ejected from a rotary printing press. These wrapping devices, together with the necessary means for their feeding, for subdivision of the stream of printed products laid out by the rotation, and the also necessary means for reuniting the branched streams represent considerable investment and require a large amount of space.
In publications U.S. Pat. No. 5,632,476, EP-0019606 or U.S. Pat. No. 4,160,687 it is suggested to improve the handlability of magazines by affixing at least one adhesive strip on the front cover, tensing it over an open magazine edge and then affixing it to the back cover. These adhesive strips hold together the magazine and, if applicable, supplements inserted therein in a unit, however, are in no way capable of protecting these when used without covering sheet.
In publication EP-0676354, it is also suggested to provide printed products such as e.g. magazines with a folded covering sheet and to seal this sheet in a suitable manner, such that again a unit suitable for distribution is created and the printed product is additionally protected, at least to a restricted degree. The covering sheet e.g. comprises a pre-fold, which, for the sealing, is applied to the edge of the magazine and is affixed on the opposite side, e.g. by means of gluing. The advantage of wrapping methods with the aid of covering sheets is that for wrapping, the same devices may be used as for the compiling of the printed product to be wrapped (e.g. device for inserting or collecting of printed product parts or of printed product and supplements), without having to substantially extend or adapt these devices for the additional functions. Known devices for the named processing steps also comprise capacities, which are sufficient for on-line processing of a stream of printed products laid out by a rotation, without subdivision. Like the plastic film, the covering sheet is also an object, which must be supplied in addition to the printed product and which, directly after delivery, must be disposed of in suitable manner by the recipient. Furthermore, compared to the plastic film, the covering sheet exhibits the disadvantage, that it is normally not transparent and thus would have to, if applicable, be printed on correspondingly for identification of the printed product.
The invention now has the object to further develop the covering sheet described in short above, in particular for newspapers and magazines with supplements. The covering sheet according to the invention shall, as far as possible, unite the advantages of the named wrapping with transparent plastic film and the wrapping with a covering sheet and shall eliminate their disadvantages as far as possible. In other words, the covering sheet, according to the invention, shall be suitable to unite the printed product to form a simply handlable unit suitable for distribution and for at least a restricted degree of protection, wherein it shall be possible to identify the printed product in simple manner without a corresponding printing on the covering sheet, wherein the covering sheet according to the invention shall, nevertheless, make it possible to wrap the printed products with known devices and large capacities and wherein the covering sheet, according to the invention, shall in particular relevantly reduce the waste problem of the wrapping in plastic film or the known covering sheets. Furthermore, it is an object of the invention to provide a corresponding wrapping method.
These objects are achieved by the covering sheet or the unit consisting of covering sheet and printed product respectively, in particular the unit consisting of covering sheet, newspaper or magazine and supplements and by the method for wrapping of newspapers and magazines as they are defined in the claims.
The covering sheet according to the invention has, like known covering sheets, a rectangular or square format, which substantially has the double size of the printed product to be wrapped or a slightly larger size. The covering sheet according to the invention consists of paper or a plastic material having a stiffness approximately like paper and it is advantageously, again like known covering sheets, folded into a front side and a back side or it comprises an approximately central spine line with a structure, which allows easy folding or bending along this spine line. The covering sheet, according to the invention, additionally comprises a completely or partly punched-out region, wherein the punched-out region is, due to the punching out and possibly due to a corresponding printing, equipped for a function different to the covering or wrapping function respectively.
A completely punched-out region of the covering sheet, according to the invention, is in particular a window, through which relevant regions of the wrapped printed product, in particular title and/or headline of the wrapped newspaper or magazine are visible. A partly punched-out region of the covering sheet according to the invention, e.g. defined by a perforation line and, thus, easily removable from the covering sheet, is, e.g. by means of a corresponding printing or further provisions, equipped for further functions. This kind of removable region is e.g. a reply card, a voucher, a collector's item, a toy, (e.g. puzzle or punch-out sheet), a pocket for a CD or a different flat object or part of the named objects. The partial punching out of a region may also apply to a surface layer of a multi-layer covering sheet, wherein the surface layer is affixed to an inner layer by peelable means and the punched-out region can be peeled off and affixed somewhere else. As is yet to be shown a partially punched-out region may also be equipped as a means for sealing the covering sheet around the printed products packed within.
For packaging, the covering sheets according to the invention are positioned around the printed products to be packed for which purpose sheet and printed products are e.g. fed into an inserting system. Hereby, the covering sheets are inserted into the insertion compartments first and opened and then the printed products are inserted into the covering sheets. For sealing the covering sheets e.g. adhesive tape is used in an inherently known manner or adhesive-tape-like regions are created by spraying on of a plastic material. For sealing it is also possible to affix the regions protruding over the printed products to be packed by means of gluing or stitching them together with other regions. Where appropriate, the regions of the covering sheet equipped for sealing the covering sheet are prepared before the sealing step in a suitable manner by means of local reinforcement, application of adhesive, partial removal from the covering sheet, by folding and/or by unfolding. These kind of preparative steps may be carried out when manufacturing the covering sheets and/or directly before or during the packing.
The method according to the invention is carried out with the aid of an inserting system (e.g. inserting drum), wherein the inserting system is advantageously also equipped for the steps for sealing the covering sheet. It is also possible to bring the newspaper or magazine together with the covering sheet in an additional unit and to feed them into the inserting system together, wherein the supplements are inserted. The packing, and in particular the first step of the sealing, may also be carried out while the products are being conveyed by one or several gripper conveyors.
The covering sheet according to the invention, which is particularly suited for packaging of newspapers or magazines together with diverse supplements and the packing method according to the invention are described in more detail in connection with the following figures, whereby
The front side 1.1 of the covering sheet 1 comprises as a completely punched-out region a window 6, which is positioned such that e.g. the title and possibly the headline of the printed product 2 are visible through it. The window 6 is possibly covered by a transparent layer of material, wherein the transparent layer of material may be applied on the inside or the outside of the covering sheet.
In addition to the window 6, the covering sheet according to
A further only partially punched-out region 7 of the covering sheet according to
The adhesive strips 4 shown in
If the covering sheet region 20 protruding beyond the rear side 1.2, shown in
In addition to a window 6, which is e.g. aligned to the title of the printed product 2, the covering sheet comprises two mutually aligned, partially punched-out regions 7, which are equipped for a sealing function. The partially punched-out regions 7, of which only the one on the front side 1.1 of the covering sheet 1 is visible in
Advantageously, the covering sheets are prepared for the sealing step directly before being brought together with the printed products, by moving the partially punched-out regions outwards and folding them. If necessary, the pre-folded lines 22 and, in particular, their end regions can be reinforced by application of a reinforcing layer.
