Patent number: 9365377Abstract: A splicing tape and a method of using such tape to equip a wound roll for flying splice. The tape includes a first and second carrier and two strips of laminating composition disposed between them, each strip joining the first carrier to the second carrier. The carriers have a first and a second layer of pressure-sensitive, laminating composition and a first and a second layer of pressure-sensitive adhesive. The strips of laminating composition are disposed such that they are not in direct contact with one another. They form a predetermined breakage point. The splicing tape is adhered to the roll such that part of the first layer of pressure-sensitive adhesive forms a first bonding area, the end region of the uppermost ply of the wound roll, and the second layer of pressure-sensitive adhesive forms a second bonding area to the roll, which is located partly below the first bonding area.Type: GrantFiled: December 15, 2009Date of Patent: June 14, 2016Assignee: tesa SEInventors: Christoph Nagel, Niels Czerwonatis, Stefan Wulf, Jens Nootbaar

Patent number: 8252402Abstract: An adhesive tape for flying splice of flat web material which has been wound to form rolls, the adhesive tape having at least one carrier layer and a layer of adhesive, at least part of that surface of the carrier layer that faces that layer of adhesive being optically detectable, or optically detectable means being provided between the carrier layer and the layer of adhesive, and the layer of adhesive being designed such that the optical detection can be made through the layer of adhesive. The adhesive tape is modified such that its gloss value, i.e. the ratio of directed fraction and diffusely reflected fraction of the light stream incident on the surface, on the external surface of the layer of adhesive is reduced by at least 20% relative to an unmodified adhesive tape of otherwise identical construction.Type: GrantFiled: April 21, 2010Date of Patent: August 28, 2012Assignee: tesa SEInventors: Christoph Nagel, Niels Czerwonatis, Christian Forsbach, Kerstin Götz
