Embodiment Construction

[0027] An apparatus for producing the adhesive tape 1 is shown in the figure. It can be seen from the cross-sectional view of FIG. 2 that, by way of example and not limitation,

[0029] According to this example and without limitation, the two adhesive strips 4 are identically designed and have the following widths,

[0031] The material web 2 is, without limitation, a web made of fabric, in particular polyester fabric. In principle, the material web can also be

[0033] Within the scope of this exemplary embodiment, the crosslinking unit 7 is assigned to the respective surfaces of the material web 2 in two parts. This

[0034] In the machine direction or longitudinal direction L of the material web 2, a sensor 8, 9 is first visible in the overview diagram according to FIG. 1,

[0036] The material web 2 is detected by means of sensors 8, 9. For this purpose, the sensors 8, 9 are arranged and placed on the surface of the material web 2

[0038] The respective values ​​for the di...

Abstract

The invention relates to a method for the production of an adhesive tape (1), in which first a material web (2) made of carrier tape material is conveyed by an unwinding unit (3); subsequently in a coating application unit (6 ) to the conveyed material web (2) on at least one surface with at least one adhesive strip (4); then by means of a cutting device (10) the material web (2) equipped with the adhesive strip (4) is cut into at least two longitudinal strips and make multiple individual adhesive tapes (1). According to the invention, it is characterized in that the material web (2) and / or the cutting device (10) are aligned transversely (Q) by means of sensors (8, 9) which detect the material web, so that by means of the cutting device (10 ) The correspondingly generated longitudinal cutting surfaces (S) are introduced precisely in position into the material web (2).

Description

Method and apparatus for making adhesive tape technical field The present invention relates to a kind of method for making adhesive tape, comprising the following method steps: - conveying a material web made of carrier tape material by an unwinding unit; - then in the coating application unit, the conveyed material web is provided on at least one surface with at least one adhesive dosage strips; - The material web provided with the adhesive strip is then cut into at least two longitudinal strips by means of a cutting device and produced Multiple individual adhesive tapes. Background technique [0005] A method and an associated apparatus of the type mentioned at the outset are known, for example, from EP 2 744 865 B1 of the applicant. here, The glue or adhesive is generally applied without contact to the carrier web and the carrier web is then cut in the machine direction into a plurality of individual glue sticky tape. In the region of the coating application...
