This application claims the priority of German Patent Document No. 10 2007 040 969.0, filed Aug. 30, 2007, the disclosure of which is expressly incorporated by reference herein.
The invention relates to an apparatus and method for webbing-up a printing substrate web or a partial web in, for example, a turner bar nest and/or folder superstructure of a web-fed rotary printing press, in particular manually.
Webbing-up a printing substrate web in a web-fed rotary printing press by means of an automatic webbing-up device is already known from the prior art. In this regard, reference is made to “Handbuch der Printmedien” [Handbook of Print Media], Helmut Kipphan, Page 278, Springer Verlag [Springer Publishers], Year 2000. The webbing-up device known from the prior art can web-up an unturned and undivided printing substrate web starting from a reel changer up to a former of the web-fed rotary printing press. The webbing-up devices known from the prior art are not suitable for webbing-up turned printing substrate webs or partial webs of the webbed-up web, e.g., through the turner bar nest and folder superstructure, and thus, for conveying them to a former. As a result, there is a need for a simple, universally usable and cost-effective webbing-up aid and method which can be used to web-up a printing substrate web or partial web in all regions such as, for example, a turner bar nest and/or folder superstructure of a web-fed rotary printing press, in which an automatic webbing-up device is not available.
Starting herefrom, the present invention is based on the objective of creating a novel, simple, universally usable and cost-effective webbing-up aid and method for webbing-up a printing substrate web or partial web, for example, in a turner bar nest and/or folder superstructure, of a web-fed rotary printing press.
The inventive webbing-up aid and method includes a threading tip for manually threading the webbing-up aid along a web path being webbed-up, e.g., in the turner bar nest and/or folder superstructure, a clamping piece for clamping one end of the printing substrate web or partial web being webbed-up, and a cable-like connecting element positioned between the threading tip and the clamping piece, wherein the clamping piece is comprised of two magnetic clamping sections that can be pivoted relative to each other, between which the end of the printing substrate web or the partial web being webbed-up can be clamped, and wherein the threading tip is also embodied to be magnetic so that when the webbing-up aid is being threaded, for example, in the turner bar nest and/or folder superstructure, the threading tip can be can be placed on metallic or metallized web guide elements.
The inventive webbing-up aid is used for webbing-up a printing substrate web or partial web, e.g., in a turner bar nest and/or folder superstructure of a web-fed rotary printing press, such as, for example, a newspaper printing press. The webbing-up device can be threaded easily, e.g., in the turner bar nest and/or folder superstructure, using the threading tip, which is embodied to be magnetic, wherein in this case, the webbing-up aid can be placed by a printer at hard-to-access locations on metallic or metallized web guide elements without the risk of the threading tip falling off and necessitating that the threading process be re-started. The printing substrate web or partial web being webbed-up can be clamped between two magnetic clamping sections of a clamping piece. A cable-like connecting element runs between the clamping piece and the threading tip. The web path being webbed-up manually can already be prepared with the webbing-up aid before production is started.
Preferred developments of the invention are yielded from the following description. Exemplary embodiments of the invention are explained on the basis of the drawings.
a to 3d illustrate a progression of steps in the use of the inventive webbing-up aid.
The threading tip 11 of the inventive webbing-up aid 10 is used for manually threading the webbing-up aid 10, for example, in the turner bar nest and/or folder superstructure. The threading tip 11 is embodied to be magnetic, and namely made of a magnetic film, wherein the magnetically embodied threading tip can be placed during threading of the same, for example, in the turner bar nest or folder superstructure of a web-fed rotary printing press according to
The threading tip 11 of the inventive webbing-up aid 10 is preferably embodied exclusively on one side to be magnetic, wherein at least on one side in the region of a tip 15 of the same is designed to be non-magnetic. This guarantees that a threading tip 11 placed on a web guide element 14 can be easily grasped and easily removed from the web guide element 14.
The clamping piece 12 of the inventive webbing-up aid 10 that is opposite from the threading tip 11 is formed of two magnetic clamping sections 16, 17, which can be pivoted relative to each other, wherein one end of a printing substrate web or partial web 18 (see
The connecting element 13 running between the threading tip 11 and the clamping piece 12 is embodied to be cable-like, preferably as a plaited, elastic, flexible connecting cable with a length between 5 m and 20 m. The length of the connecting cable 13 depends of course on the length of the path through the regions of a web-fed rotary printing press through which a printing substrate web or partial web must be webbed-up or threaded.
According to
As a result, the inventive webbing-up aid is comprised of a magnetic threading tip 11, an elastic, cable-like connecting element 13, and a magnetic clamping piece 12 that can be opened up. When transferring and winding around web guide elements, a magnetic side of the threading tip 12 can be placed on the web guide element so that the same adheres to the web guide element and cannot slip away. It is possible for it to grip the web guide elements securely.
The procedure depicted in
The foregoing disclosure has been set forth merely to illustrate the invention and is not intended to be limiting. Since modifications of the disclosed embodiments incorporating the spirit and substance of the invention may occur to persons skilled in the art, the invention should be construed to include everything within the scope of the appended claims and equivalents thereof.
