An adhesive tape having a carrier and an adhesive layer applied to at least one side of the carrier, wherein the carrier is a thread-stitched web nonwoven carrier produced from a preconsolidated base web of staple fibers. Mutually parallel threads are stitched into the base web to form the final thread-stitched web nonwoven carrier, wherein the ultimate tensile strength of the preconsolidated but not as yet overstitched base web is less than 2 N/cm. In embodiments, the ultimate tensile strength of the preconsolidated but not as yet overstitched base web is below 1 N/cm or below 0.5 N/cm.

1. An adhesive tape consisting of a carrier and an adhesive layer applied to at least one side of the carrier, wherein the carrier is a final thread-stitched web nonwoven carrier produced from a base web of staple fibres that is preconsolidated, before overstitching with stitching threads, by needling to produce a preconsolidated base web, wherein mutually parallel stitching threads are stitched into the preconsolidated base web to form the final thread-stitched web nonwoven carrier, wherein the ultimate tensile strength of the preconsolidated, but not as yet overstitched, base web is less than 1 N/cm, wherein an angle made by at least 50% of the staple fibres relative to an axis extending in a transverse direction of the base web is between 5° and 45°. 2. The adhesive tape according to claim 1, wherein the ultimate tensile strength of the preconsolidated, but not as yet overstitched base web, is below 0.5 N/cm. 3. The adhesive tape according to claim 1, wherein the base web consists of polyester, polypropylene, polyethylene or polyamide fibres. 4. The adhesive tape according to claim 1, wherein the stitching threads consist of polyester, polypropylene, polyethylene or polyamide. 5. The adhesive tape according to claim 1, wherein the stitching threads form a parallel arrangement in the machine direction. 6. The adhesive tape according to claim 1, wherein the basis weight of the final thread-stitched web nonwoven carrier is between 30 g/m2 and 180 g/m2. 7. The adhesive tape according to claim 1, wherein a material of the base web is compacted by calendering. 8. The adhesive tape according to claim 1, wherein the needling is present in a range from 1 needle/cm2 of the base web to 50 needles/cm2 of the base web. 9. The adhesive tape according to claim 1, wherein the adhesive is based on natural rubber, synthetic rubber, acrylate or silicone. 10. The adhesive tape according to claim 1, wherein the adhesive comprises an acrylate pressure-sensitive hotmelt adhesive. 11. The adhesive tape according to claim 1, wherein the angle made by at least 50% of the staple fibres relative to the axis extending in the transverse direction of the web is between 15° and 30°. 12. The adhesive tape according to claim 1, wherein a proportion of staple fibres forming an angle between 5° and 45° relative to an axis extending in the cross direction of the web is above 80%. 13. The adhesive tape according to claim 12, wherein the proportion of staple fibres forming an angle between 5° and 45° relative to the axis extending in the cross direction of the web is above 95%. 14. The adhesive tape according to claim 1, wherein a number of overstitching threads is below 30 threads/25 mm width of carrier. 15. The adhesive tape according to claim 14, wherein a number of stitching threads is between 10 to 24 threads/25 mm width of the carrier. 16. The adhesive tape according to claim 1, wherein the adhesive is applied, in a form of at least one adhesive stripe, to the carrier in the longitudinal direction of the adhesive tape, wherein the at least one adhesive stripe has a width less than a width of the carrier. 17. The adhesive tape according to claim 16, wherein the width of the at least one adhesive stripe is 10 to 80% of the width of the carrier, and further wherein the at least one adhesive stripe is located at one edge of the carrier. 18. A method for jacketing elongate material, the method comprising: passing the adhesive tape according to claim 1 around an elongate material in a helical line. 19. A method for jacketing elongate material, the method comprising: enveloping an elongate material with the tape according to claim 1 in an axial direction. 20. A thread-stitched web nonwoven carrier produced from a base web of staple fibres that is preconsolidated, before overstitching with stitching threads, by needling to produce a preconsolidated base web, wherein mutually parallel stitching threads are stitched into the preconsolidated base web to form the thread-stitched web nonwoven carrier, wherein the ultimate tensile strength of the preconsolidated, but not as yet overstitched, base web is less than 1 N/cm, wherein an angle made by at least 50% of the staple fibres relative to an axis extending in a transverse direction of the base web is between 5° and 45°.
