  • Publication number: 20210261827
    Abstract: An adhesive tape for winding around cables includes a carrier (T) with a first layer (1) made of woven fabric and with a second layer (2) made of a sewn bonded fiber fleece, wherein both layers rest fully upon each other. Between the first layer (1) and second layer (2) there is a first adhesive layer (3), wherein the second layer (2) features at least in part a second adhesive layer (4) which is arranged on the opposite side to the first adhesive layer (3). The first layer (1) features a surface weight of 100 to 200 g/m2, wherein the material of the first adhesive layer (3) comprises an adhesive and the material of the second adhesive layer (4) comprises an adhesive. The second layer (2) features a surface weight of 60 to 160 g/m2.

  • Patent number: 11077640
    Abstract: An adhesive tape, including a substrate including a stitched fleece and an adhesive layer applied one-side on the substrate, wherein the stitched fleece is formed from fibers, which are stitched with stitching yarns. A manually tearable adhesive tape is disclosed, with improved abrasion resistance properties together with a high noise damping. The stitching yarns may be stitched with a fineness of at least F24.

  • Patent number: 10857565
    Abstract: A self-windable, transversely tearable textile industrial adhesive tape (1) having a tape-shaped substrate (2) which has a thickness (D2) in the range of 0.05 mm to 1.8 mm, consisting of a knitted fabric (3) having stitches (5) made of yarn (4), and which is provided on one side with a pressure-sensitive adhesive coating (6) which is applied directly to the substrate (2) with a specific weight per unit area in the range of 20 g/m2 to 300 g/m2. In order to obtain improved manufacturability as well as improved functional characteristics, in particular an improved dimensional stability during the process, while preserving the advantages of using a substrate (2), it is proposed that the substrate (2) includes weft threads (7) running mutually parallel in the transverse direction, which weft threads (7) are held in the stitches (5) of the knitted fabric (3).

  • Patent number: 10549500
    Abstract: An adhesive tape includes a carrier having a stitch bonded nonwoven and an adhesive layer that is applied to one side of the carrier, wherein the stitch bonded nonwoven is formed from fibers, which are stitched with sewing threads. The adhesive tape has improved abrasion resistance while simultaneously avoiding flagging. The sewing threads may have a thread linear density of at least 80 dtex.

  • Patent number: 9982168
    Abstract: An adhesive tape having a carrier including a stitch-bonded web and an adhesive coating applied on at least one side of the carrier. The stitch-bonded web may contain fibers composed entirely from polyester (PES) and sewn by means of at least one sewing thread. The stitch-bonded web contains bicomponent fibers in addition to the fibers may be composed of PES.
