Abstract
The method relates to tape connecting device (1) and a method for connecting a first tape to a second tape for providing a tape string. In the tape connecting device (1) when continuously conveying the first tape an end section of the first tape is connected to a start section of the second tape by an adhesive connection by a liquid (in particular water) arranged in a connecting section. Furthermore, the invention relates to a method for connecting two tapes, a processing system and a use of a method. The inventive tape connecting device (1) and the method can in particular be used for a continuous provision of a security tape for a security document as a banknote.
Claims19
A method for connecting an end section of a first tape to a start section of a second tape for building a tape string comprising at least the first tape and the second tape, the tape string being supplied to a processing process, the method comprising the following method steps:
- a) connecting the end section of the first tape to the start section of the second tape by an adhesion of a liquid arranged between the end section of the first tape and the start section of the second tape so that a tape string comprising the first tape and the second tape is built, the liquid being at least one of
- a non-hardening liquid and/or
- a liquid used in the subsequent processing process and/or
- water,
- and
- b) supplying the tape string to the processing process without a stop.
A tape connecting device comprising
- a) a first conveying path for a first tape and
- b) a second path for a second tape,
- c) a wetting device by which the first tape and/or the second tape is wet by a liquid in a connecting section,
- the liquid being at least one of
- a non-hardening liquid,
- a liquid used in a subsequent processing process and
- water, and
- d) a joining device adapting the first conveying path and/or the second path, the joining device
- da) comprising an inactive operating state wherein in a working region of the joining device the first conveying path for the first tape and the second path for the second tape are arranged with a distance from each other and
- db) comprising an active operating state wherein the first conveying path for the first tape and the second path for the second tape are joined to each other in a working region of the joining device so that a start section of the second tape and an end section of the first tape contact each other in the connecting section so that an adhesive connection between the start section of the second tape and the end section of the first tape is established in the connecting section due to the wetting with the liquid.
