AI Technical Summary

Technical Problem

Existing methods for sheathing cable harnesses using adhesive tapes are inefficient, time-consuming, and require frequent replacement of large tape reservoirs, which are often too heavy for automated applications, leading to delays and increased costs.

Method used

A method involving the use of two or more web-shaped adhesive elements applied offset along the strand direction to encase unbranched sections, eliminating the need for rotary windings and allowing for high-reproducibility, reliable, and cost-efficient sheathing using large adhesive reservoirs.

Benefits of technology

The method enables efficient, automated, and high-performance coating of unbranched sections in strand systems, reducing equipment costs and setup times while ensuring stable and mechanically resilient protection.

Abstract

The invention relates to a method for sheathing unbranched sections (10) in strand systems (12), comprising the process steps of: a) producing or providing a strand system (12) comprising at least one unbranched section (10), b) producing or providing two or more web-shaped bonding elements (14a, 14b), one or more of which are web-shaped adhesive elements (15a, 15b) comprising an adhesive layer, and c) sheathing the strand system (12) in the unbranched section (10) with the two or more web-shaped bonding elements (14a-b) using an application device (16), wherein the two or more web-shaped bonding elements (14a-b) are offset along the strand direction (S) over the circumference of the unbranched section (10). R) of the unbranched section (10), wherein the two or more web-shaped adhesive elements (14a-b) are applied to the unbranched section (10) such that each web-shaped adhesive element (15a-b) with its adhesive layer is aligned orthogonally to the strand direction (S R ) standing transverse direction at least one other web-shaped adhesive element (14a-b) is contacted on both sides, so that an overhang area (18) is formed in the contact area, and so that each web-shaped adhesive element (14a-b) is materially bonded to at least one other web-shaped adhesive element (14a-b) with respect to the transverse direction.
