Abstract: The adhesive tape applicator (3) comprises rollers for transporting, enveloping and compressing, a slide or ball element for guiding the tape to complete or partial envelope end, a symmetrical or asymmetric wall surface of thin plate (1), a slide and/or ball bearing for encompassing a plate to be adhered lying in x/y- y/z-plane, where the applicator is backlash-free into x/z- and y/z- plane, an envelope roller and/or a compressing roll, and a corner forming and cutting device. The envelope roller is attached parallel and vertical to a plate plane. The adhesive tape applicator (3) comprises rollers for transporting, enveloping and compressing, a slide or ball element for guiding the tape to complete or partial envelope end, a symmetrical or asymmetric wall surface of thin plate (1), a slide and/or ball bearing for encompassing a plate to be adhered lying in x/y- y/z-plane, where the applicator is backlash-free into x/z- and y/z- plane, an envelope roller and/or a compressing roll, and a corner forming and cutting device. The envelope roller is attached parallel and vertical to a plate plane, and is variably adjusted to a desired envelope width around plate edges. An adhesive tape (4) is wrapped by the envelope roller around the plate edges. The compressing roller of the adhesive tape is defined in an end position of the plate. The adhesive tape applicator is inserted to plate straight lines by feeding the tape to the edge of the thin plate perpendicular to the plate plane located in the tape-applicator, embracing the applicator around the plate by the slide or ball bearing, setting a tape cover at a top side and/or bottom side of the thin plate via a position of the perpendicular variable band-guide rollers, gluing the plate edge by guiding the applicator with the tape located next to a corner/curve, pressing the corner shaper, which bisects the corner point for folding the tape around the corner and for forming the excess tape material by folding the tape material at the corner simultaneously at both edges of the thin plate, separating the excess tape material by cutting knives of a corner cutting device, grappling the tape around the plate edge by the envelope roller, compressing the tape at the end position of the plate using the compressed roller, and separating a tapered tape (2) by the cutting device when reaching an identifier on a swivel arm of the tape guide roller after complete rotation of the applicator around the thin plate. A gap and a cover-free adhesive joint are attained with the separate end of the tape depending on the intended application, and a cover of the tape end is attained on the beginning of the tape or a tape-free gap is formed between the beginning of the tape and the end of the tape. The applicator is again removed from the plate after the step of separating the tapered tape and the step of feeding the envelope roller and the compressing roller via an intersection point.
