  • Publication number: 20230278142
    Abstract: 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.

  • Patent number: 11498791
    Abstract: 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).

  • Patent number: 10720268
    Abstract: A sheath for wrapping an elongated object is formed by an adhesive tape having a base strip having inner and outer faces, a first adhesive on the outer face, an adhesive-free overlay strip adhered to the first adhesive coating so as to leave a first exposed edge band on at least one of two longitudinal edges of the tape, and a second adhesive layer covering only part of an area of the inner face.

  • Patent number: 10395803
    Abstract: 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.

  • Patent number: 10000669
    Abstract: 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.

  • Patent number: 9222002
    Abstract: 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.
