Publication number: 20230278142Abstract: A method of making adhesive tape has the steps of advancing a substrate band longitudinally in a machine direction from a supply to an array of laser units, cutting the band longitudinally with the laser units into a plurality of longitudinal strips, and then cutting each of the longitudinal strips longitudinally into a plurality of tapes. An adhesive is applied to a face of each of the tapes, and the tapes are wound up individually.Type: ApplicationFiled: March 3, 2022Publication date: September 7, 2023Inventors: Peter RAMBUSCH, Rene RAMBUSCH, Kay RUHNAU, Timo LEERMANN

Patent number: 11498791Abstract: The subject matter of the present invention is a method and a device for producing an adhesive tape (1). First a material web (2) comprising a carrier tape material is supplied from an unwinding unit (3). The supplied material web (2) is subsequently provided on at least one surface with at least one adhesive strip (4) in a coating unit (6). The material web (2) provided with the adhesive strip (4) is then cut into at least two longitudinal strips with the aid of a cutting device (10) and made up into individual adhesive tapes (1). According to the invention, a sensor (8, 9) scanning the material web is used to align the material web (2) and/or the cutting device (10) in the transverse direction (Q) in such a way that a longitudinal cut (S) respectively produced with the aid of the cutting device (10) is introduced in an exact position into the material web (2).Type: GrantFiled: August 22, 2018Date of Patent: November 15, 2022Assignee: CERTOPLAST TECHNISCHE KLEBEBAENDER GMBHInventors: Peter Rambusch, Rene Rambusch, Kay Ruhnau

Patent number: 10395803Abstract: The present invention relates to a method for the production of a cladding for elongated material (2), in particular a sheath for cable sets. In this method, an adhesive tape (3, 4) consisting of a carrier (4) and a first adhesive coating (3) which substantially fully covers the front side of the carrier (4) is combined with an adhesive-free carrier tape (5) such as to form a laminate (3, 4, 5). This is carried out such that the adhesive tape (3, 4) is applied to the carrier tape (5) with its first adhesive coating (3) in such a way that a first projection (Ü1) is defined along at least one of the two longitudinal edges of said adhesive tape. According to the invention, the carrier (4) of the adhesive tape (3, 4) is additionally provided with a further second adhesive coating (7) substantially in parts of its rear side.Type: GrantFiled: August 21, 2015Date of Patent: August 27, 2019Assignee: certoplast Technische Klebebaender GmbHInventors: Andreas Franz Hohmann, Timo Leermann, Kay Ruhnau, Peter Rambusch

Patent number: 10000669Abstract: The subject matter of the invention is a method for the production of a cladding (1) for elongated material (2), in particular a sheath for cable sets. In this context, two adhesive tapes (3, 4) that are provided at least on one side with an adhesive coating (3) are axially spaced apart from one another by means of a carrier tape (5) are joined to form a laminate (3, 4, 5). For this purpose, both adhesive tapes (3, 4) arc each joined, on the side thereof with the adhesive coating, with the carrier tape (5), in the longitudinal direction, while defining a free region (6) limited by both adhesive tapes (3, 4). According to the invention, the carrier tape (5) is configured free of adhesive coating and is only provided with an own adhesive coating (7) at least in the free region (6) after the laminate (3, 4, 5) has been produced.Type: GrantFiled: August 11, 2015Date of Patent: June 19, 2018Assignee: CERTOPLAST TECHNISCHE KLEBEBAENDER GMBHInventors: Timo Leermann, Peter Rambusch, Kay Ruhnau, Andreas Hohmann

Patent number: 9222002Abstract: The present invention relates to a method for producing an adhesive tape (2). The adhesive tape (2) possesses a tapelike carrier (3) and at least one strip (4; 4a, 4b) of adhesive which is applied to the carrier (3) on at least one side. Here, first of all, a carrier web (1), coming from a supply unit (7), is supplied to at least one coating unit (9, 10). The coating unit (9, 10) then generates the at least one strip (4; 4a, 4b) of adhesive on the carrier web (1) in its longitudinal extent, by carrying out coating with an adhesive. Lastly, the carrier web (1) is slit in the longitudinal direction into the individual adhesive tapes (2); the two last-mentioned method steps may also be run in the opposite order.Type: GrantFiled: August 17, 2012Date of Patent: December 29, 2015Assignee: certoplast VORWERK & SOHN GMBHInventors: Thorsten Meier, Peter Rambusch, Kay Ruhnau
