Definitions
- the invention relates to a band, preferably for wrapping elongate material such as in particular lines or cable sets, from a carrier, to which preferably at least on one side a pressure-sensitive adhesive coating is applied. Furthermore, the invention relates to the use of the tape and a wiring harness, which is covered with the tape according to the invention.
- bundles of a plurality of electrical leads are wrapped prior to installation or in the already assembled state, in order to reduce the space requirement of the bundle of cables by means of bandaging and to additionally provide protective functions.
- film adhesive tapes a certain protection is achieved against ingress of liquid, one obtains damping properties with airy and voluminous adhesive tapes based on thick nonwovens or foam as a support, with the use of abrasion-resistant backing materials, a protective function against scuffing "and rubbing is achieved.
- Abrasion resistance is a measure of the rub resistance of adhesive tapes.
- ISO 6722 Chapter 9.3 "Scrape abrasion test” (April 2002 issue)
- LV 312 the abrasion resistance of adhesive tapes in accordance with LV 312.
- test specimen with a length of about 10 cm is glued to a 5 or 10 mm thick steel mandrel in a single longitudinal direction using a steel wire with a diameter of 0.45 mm and a weight load of 7 N in the center over the specimen
- the number of double strokes is determined until the test specimen is destroyed
- the direction of movement of the steel wire is aligned parallel to the warp threads.
- the result of the test is called the abrasion class of the test specimen, mentioning the diameter of the mandrel and the weight load.
- the adhesive tapes are classified in classes A to F according to Table 1.
- an adhesive tape can achieve, for example, the abrasion class D at 10 mm and the abrasion class C at 5 mm.
- Table 1 Classification of the abrasion classes according to LV 312
- Highly abrasion-resistant adhesive tapes are adhesive tapes with abrasion class D.
- Fabrics consist of warp threads (longitudinal direction, machine direction, also corresponds to the longitudinal direction of the adhesive tape produced therefrom) and weft threads (transverse threads).
- the threads are usually woven in plain weave. Other types of weave include satin weave (also known as satin, which is regular and irregular) and twill weave.
- Twill-weave twill weaves (for example, a "2 over 1 twill") create what is known as a twill bifurcation that runs diagonally to the machine direction Twill weave twill weaves tend to be slightly softer than plain weave fabrics, especially in the diagonal direction, where the flexural stiffness is lower may be an advantage for tapes made therefrom.
- the fabrics can be subsequently dyed or consist of spun-dyed yarns.
- the threads can consist of spun yarns or filament yarns (continuous yarns). Usually filament yarn is used. This consists of a fixed number of individual filaments and can be textured or smooth and point-solidified or unconsolidated.
- Fibers are used to make the yarns.
- staple fibers (the term staple fibers is used synonymously), which have a limited length.
- endless fibers also called filaments, which have a virtually unlimited length.
- Filament refers to a textile technical term under which. a chemically produced by various methods, practically endless fiber is understood as part of filament yarns and cables. Filament yarn of several filaments is called multifilament yarn, filament yarn of only one filament monofilament yarn.
- the cross-titer of a fabric is the number of transverse threads (weft threads) per centimeter multiplied by the thread weight of the transverse threads in dtex.
- the unit is dtex / cm.
- Polyester fabrics used as a carrier for cable wrapping tapes typically have basis weights between 60 and 180 g / m 2 .
- the abrasion resistance of an adhesive tape increases with the basis weight of the polyester fabric used.
- Polyester fabric tapes for cable winding with abrasion protection are known. Under the trade names “tesa® 51026” or “Coroplast 837X” they are used as cable wrapping tapes.

Due to the numerous warp threads with high yarn weights, the adhesive tapes are highly abrasion-resistant, thus meeting an abrasion class D according to LV 312 with a 10 mm mandrel diameter.
- the flagging tendency is reduced by a high adhesive strength of the adhesive tape on the own back after the application.
- a high bond strength requires, inter alia, a high adhesive application of the adhesive tape.
- flagging tendency can be reduced because of reduced flexural stiffness.

'Where the adhesive tape used to wrap a wire harness by using the adhesive tape being guided in a spiral movement around the cable harness, the sheath of the wire harness can be carried out so that the adhesive of the adhesive tape only on the tape itself, while the material with no adhesive comes into contact.
- the thus-sheathed wire harness has a very high flexibility due to the lack of fixation of the cables by any adhesive. Thus, its bending ability during installation - especially in narrow passages or sharp turns - significantly increased. If a certain fixation of the adhesive tape on the material is desired, the sheath can be made such that the adhesive strip is glued to a part on the tape itself and to another part on the estate. -
- the strip is applied centrally on the adhesive coating, resulting in two adhesive strips extending on the longitudinal edges of the carrier in the longitudinal direction of the adhesive tape.
- the two adhesive strips respectively present at the longitudinal edges of the adhesive tape are advantageous, especially if one, which is usually narrower than the second strip, than Fixing aid is used and the second, wider strip serves as a closure.

- these can be application methods via a nozzle or a calender.
- a backside lacquer can be applied to favorably influence the unwinding properties of the adhesive tape wound on the Archimedean spiral.
- This backcoat can be equipped with silicone or fluorosilicone compounds as well as with Polyvinylstearylcarbamat, Polyethyleniminstearylcarbamid or fluoroorganic compounds as abhesive substances.
- the back coat should be used sparingly so as not to provoke flagging of the later taped adhesive tape.
- adheresive tape encompasses all flat structures such as films or film sections which are expanded in two dimensions, tapes of extended length and limited width, strip sections and the like, and ultimately also diecuts or labels.
- the adhesive tape can be rolled up on itself in the form of a roll, that is to say in the form of an Archimedean spiral, or produced with release materials, such as siliconized paper or siliconized film, covered with adhesive.

- a 19 mm wide tape is used. This is manually wrapped around a ETFE (ethylene tetrafluoroethylene) jacketed cable having a 1 mm 2 wire cross section four times (1440 °) without additional pressure. The tape is cut with scissors.
- ETFE ethylene tetrafluoroethylene
- a total of seven windings are generated around the cable.
- the flags will be added after three days, ten days and 30 days. Measure orm climate with the aid of a ruler. This is shown in FIG. 4.
- the absolute flagging value is calculated by subtracting 5 mm from the actual measured length of the lug.
- the flagging value is thus 23 mm (28 mm-5 mm).
- the flag value indicated as the result is the result of the mean value of the flagging value of the seven windings.
- the test is carried out at 40 ° C in conventional drying cabinets.
- the adhesive tape of the invention is evaluated at 40 ° C in a drying oven according to the specified SWAT method.
- a value of 10 mm is considered to be the lower limit for resistance to deflagration.
- Average values ⁇ 5 receive the grade 2
- mean values from 5 to 10 receive the grade 1
- mean values> 0 receive the grade 0.
- Carrier thickness 200 ⁇ 135 ⁇ 185 ⁇ 246 ⁇
- Hand tearability was evaluated by coating the PET fabrics of Table 2 each with 105 g / m 2 dry weight adhesive and cutting into 20 mm wide strips. Five different individuals subsequently attempted to tear each pattern transversely (perpendicular to the machine direction) and rated "hand tearable" or “non-hand tearable” accordingly. Accordingly, the samples that were rated five times as non-hand tearable received the entry 0/5. Conversely, the pattern that could be torn by all subjects received the entry 5/5.
- Example (IV) shows the advantages of the invention: High abrasion resistance of the adhesive tape with at the same time good hand tearability. These two advantages can be combined if the ratio of cross-titer to longestiter is within the limits according to the invention and the transverse threads have a cross-titer greater than 12,000.
- FIG. 5 shows a photograph which shows the tear-through behavior of the adhesive tape according to the invention in comparison to a known adhesive tape.
- the known adhesive tape consists of a fabric carrier with conventional weft threads with a thread face of 167 dtex, while in the adhesive tape according to the invention a fabric carrier is present, having weft threads with a thread weight of 660 dtex.
