Description

The The invention relates to a method for winding a running Material web, in particular a paper or board web, in which the moving material web successively on several hubs, especially reels, is wound up and in each case with The winding is started on a new core, if one formed on a previous old winding core winding roll a predetermined Diameter has reached, with the new and pre-accelerated winding core preferably directly to a winding roller, in particular a carrier drum, via whose partially outer peripheral surface the running material web is guided before winding on the winding core, is brought under training of a nip. In the running material web is at least one cut before or on the winding roller at least one cutting device under training at least a preferably integrated transfer strip attached or the running web is after passing through the between Winding roller and the new hub formed nips by means of at least a cutting device and / or preferably web-width separating device cut or severed preferably by producing a transfer strip.

Farther The invention relates to a winding machine for carrying out the Method according to the preamble the claims 26 and 27.

such Winding and winding machines are used, for example, in of paper or cardboard manufacture applied to the finished and running Paper or board web without interrupting the manufacturing process, that is without switching off the paper or board machine, successively on several hubs, which are also referred to as reels to wind up.

there must for it be ensured that the resulting from the cutting of the running material web new web start is fed to the new hub to on this afterwards to form a new winding roll.

From the European patent application EP 0 089 304 A1 (≡ US 4,444,362 ) is a Aufwickelverfahren and an associated winding machine for a moving web, in particular a paper or board web is known in which in a running web two intersecting lines are cut by means of two movable cutting body, each of spaced starting points on opposite sides of the longitudinal center line of the current Material web from converging to a section and from the intersection of divergent to opposite edges of the running material web. The tongue protrusion formed by this course of the two cutting bodies is directed onto a rotating new winding core by means of an air flow generated by a winding start device, counter to the web running direction of the moving material web.

disadvantageous At this Aufwickelverfahren that is opposite to the direction of web travel the current web of material acting air stream compresses the same, doing an uncontrollable ball of cut and running Material web generated and thus both the process reliability and the applicability of Aufwickelverfahrens greatly reduced. in the unfavorable Fall can lead to a complete crack of the running material web come in the field of winding machine, after which a time-consuming and costly transfer of the forming running web through a majority of Paper or board machine is necessary.

Furthermore, from the European patent application EP 0 543 788 A1 (≡ US 5,360,179 ) a winding method for a moving material web, in particular a paper or material web, known in which again by means of at least one cutting body a transfer strip is cut out of the running material web, it is blown by means of a blowing device preferably acting from below to a new hub and he subsequently is cut wide.

this disclosed wrapping method adheres to the disadvantage that, although the Überführstreifen is blown to the new hub for better transfer, this However, as regards their process safety and their Efficiency is too uncertain, especially in today's higher Web speeds of the running web, usually in the range of 1,200 m / min to 2,500 m / min.

Out various other publications are still further Aufwickelverfahren and winding machines for running material webs known, but all with more or less big Disadvantages are afflicted.

For example, the two German disclosures disclose DE 198 48 810 A1 (PR10788) and DE 199 44 704 A1 (PR10986 DE) Applicant's method for cutting through a running web, in particular a paper or board web, wherein the moving web in the first disclosure between a gap formed by the winding roller and a new hub and that formed on the old hub Winder roll and in the second Offenle tion is separated in front of the winding roller. Both methods rely on a self-performance of the new web start on the new hub, the self-performance, however, can be very difficult and ongoing; Process reliability, in particular at the aforementioned web running speeds of the running material web, can under no circumstances be mentioned.

Further discloses PCT Publication WO 03/050026 A1 (PR11366 WOK) the applicant a method and apparatus for transferring a running web, in particular a paper or board web, on a new hub. It is provided that at least one Initial cutting piece so introduced between the web and a winding roller is that a portion of the introduced initial separator is not covered by the material web that will be the initial separator after reaching one of the winding roller and the new hub formed nips, at least temporarily in the uncovered Area is connected to the new hub, and that at the latest at the expiration point of the web of the new hub a separation the material web is caused and / or made possible by the initial separating piece making a new, to the initial separator and the new hub bound web start is formed.

From Disadvantage of this method is that the initial separator with in the new winding roll is wrapped. This can crush the lead adjacent railway stations, Which then not salable Railway material, the so-called core committee. Consists the initial separator furthermore, of a material which is not dissolved in the pulper can, it gets back into the material cycle and ultimately leads to defects in the material web, in particular to holes. That too Procurement, storage, handling, disposal and introduction of the initial separation piece requires a high personnel and thus cost.

It So is the object of the invention, a method and a winding machine to provide the type mentioned, the improved transfer of the running web on the new hub with optimal runnability and cheap Allow investment and procedural costs.

These Task is in a first method of the type mentioned according to the invention thereby solved, that the at least one transfer strip after passing through the between the winding roller and the new hub nips formed by means of at least one Aufführeinheit to the surface of the brought new hub and pressed flat and that the new hub of the at least one performance unit on a Angular range of over 90 °, preferably of over 180 °, in particular from above 270 ° is wrapped.

The Task will continue in a second method of the beginning mentioned type according to the invention thereby solved, that the running material web after cutting or the Separation by means of at least one Aufführeinheit to the surface of the brought new hub and pressed flat and that the new hub of the at least one performance unit on a Angular range of over 90 °, preferably from above 180 °, in particular surrounded by over 270 ° becomes.

By Both procedures will ensure that the transfer strip or the running web during of their respective convictions the new hub constantly controlled and targeted become. This improves in detail the exchange security (process security) in providing a defined trailing edge of the web and elevated optimally the runnability, whereby the investment and process costs relatively cheap are. The bigger the Wrap angle to be chosen in view of the existing geometries The better this is with regard to the targeted transfer and thus also with regard to the achievable change security.

Further the inventive Aufführeinheit is suitable also for the transfer of any Type of material webs, especially for transferring heavy paper and Cardboard boxes, as they during the transfer process of the transfer strip The new hub well controlled and guided. These relatively stiff varieties are made by the Aufführeinheit safely led to the new hub, which so far by action an adhesion force or a blowing device was not possible.
