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.

Abstract: A support tape extends longitudinally along an elongated object, is wrapped around the object, and has a pair of opposite longitudinal edges, an inner face engaging the object, and an outer face turned outward away from the object. The support tape is of single-layer design and having a class D abrasion resistance according to LV 312-1. One closure strip of an adhesive compound extends along one of the faces at one of the edges, and another closure strip of an adhesive compound extends parallel to the edges, along the other face, and transversely offset on the other face from the one closure strip. It is adhered to the one closure strip. A fixing strip of an adhesive compound extends longitudinally on the inner face, offset thereon from the one and other closure strips, and adheres the tape to the object.

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).

Abstract: A sheath for an elongated object is made by first combining an adhesive tape comprised of a substrate strip and a first adhesive coating at least partially covering the substrate strip with an adhesive-free band to form a laminate. Then the substrate strip and the band are overlapped at least largely such that, at the overlap, the first adhesive coating is between the substrate strip and the band. Finally the first adhesive coating is formed at the overlap between the substrate strip and the band of a plurality of spaced adhesive substrips.

Abstract: An adhesive tape is made by hot calendering a substrate between two generally identical rolls one of which is heated to a different temperature than the other roll while rotating the rolls at the same peripheral speed to flatten one face of the substrate and reduce air permeability of the substrate by at least 15%. Then an adhesive coating is applied to at least one of the faces of the substrate.

Abstract: The invention relates to a covering for encasing an elongated object (1), in particular for making an elongated sheath (2) for cables in automobiles. The covering is provided with a support tape (3) and at least two closure strips (4) of an adhesive compound on an upper face and/or lower face of the support tape (3). The closure strips (4) extend along respective longitudinal edges of the support tape (3) and define a free area (3) between and/or next to one another. According to the invention, the support tape (3) has a single-layer design and has a class D abrasion resistance according to LV312-1 (2009).

Abstract: The invention relates to a device for producing a manually tearable textile adhesive tape. The device has a supply unit for longitudinal and/or transverse threads and a treatment device. In the treatment device, the threads supplied by the supply unit are treated with a processing liquid that attacks the fibers of the particular thread until the tear strength of the thread is reduced by approximately 5% to 60%. The device also has a weaving unit, in which the treated threads and/or untreated threads are woven with each other in order to form a carrier tape. A final coating unit serves to coat the carrier tape with a glue at least on one side.

Abstract: The invention relates to a method and a device for producing a hand-tearable textile adhesive tape. First of all, a textile carrier tape (T) is treated, using a processing liquid (4) which acts upon the fibres, for long enough for its tear-resistance to fall below 100 N/cm. The textile carrier tape (T) is then washed and neutralised, and lastly a coating comprising an adhesive is applied to at least one side of said textile carrier tape (T).

The invention also relates to an ultrasound unit (9 and 10) and/or a laser unit for producing perforations and/or cut edges in the carrier (3).

Abstract: The object of the invention is a method of making a wrapping for an elongated object (1). An adhesive tape (2, 3) comprised of a substrate strip (2) and an adhesive coating (3) at least partially covering the substrate strip (2) is combined with an adhesive-free band (4) to form a laminate (2, 3, 4).

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.
