Method of making adhesive wrapping tape for bundling cables in cars

A method of making and using an adhesive tape, the method comprising the steps of:

• providing a fabric substrate having two faces and consisting of transversely extending weft filaments and of warp filaments of a lower thread count than the weft filaments, the warp and weft filaments being so constructed that the tape is manually transversely tearable and has a longitudinal tear resistance greater than 60 N/cm;
• hot calendering the fabric substrate between two rolls;
• heating one of the rolls to a temperature above a temperature of the other of the rolls while rotating the rolls at the same peripheral speed to flatten and seal only one of the faces of the substrate, reduce a thickness of the substrate to between 0.06 mm and 0.08 mm, and reduce air permeability of the substrate by at least 15%;
• applying an adhesive coating to the other of the faces of the substrate;
• and thereafter
• manually transversely tearing a piece off the hot-calendered and flattened substrate and winding the piece around a cable bundle with the one sealed face of the substrate turned outward away from the cable bundle and the adhesive coating against the cable bundle.
