Method for jacketing elongate material, especially leads or cable looms
View Patent ↗Method for jacketing elongate material such as more particularly leads or cable looms, where an adhesive tape comprising a carrier, more particularly textile carrier with a curative composition applied to its top side and a reactive composition to its bottom side, is passed in a helical line around the elongate material, or the elongate material is wrapped in the axial direction by the adhesive tape in such a way that the curative composition and the reactive composition come into contact, the elongate material together with the adhesive tape wrapping is brought into the desired disposition, more particularly into the cable loom layout, the elongate material is held in this disposition, the curative composition reacts with the reactive composition, to produce a curing layer of composition.
1. A method for jacketing elongate material, said method comprising:
(A) providing an adhesive tape comprising a carrier having a curative composition applied to its top side and a reactive composition applied to its bottom side, the adhesive tape further comprising a release film between the carrier and the reactive composition,
(B) passing said adhesive tape in a helical line around the elongate material or wrapping the elongate material in the axial direction with the adhesive tape in such a way that the curative composition and the reactive composition come into contact,
(C) bringing the elongate material together with the adhesive tape wrapping into a desired disposition,
(D) holding the elongate material in this disposition, and
(E) reacting the curative composition with the reactive composition to produce a curing layer of composition.
2. Method according to claim 1 ,
wherein
the curative composition and/or the reactive composition, following application to the carrier, have sunken into the carrier to an extent of more than 10%.
3. Method according to claim 1 ,
wherein
the curative composition and/or the reactive composition, following application to the carrier, completely saturate the carrier.
4. Method according to claim 1 ,
wherein
the carrier has a basis weight of 30 to 250 g/m.
5. Method according to claim 1 ,
wherein
the carrier is a textile carrier.
6. Method according to claim 5 ,
wherein
the textile carrier consists of polyester or of glass fibers.
7. Method according to claim 1 ,
wherein
the reactive composition takes the form of
(A) an adhesive composition;
(B) a wet layer in solution or as a dispersion; or
(C) a composition embedded in a surface-coating material.
8. Method according to claim 1 ,
wherein
the reacting the curative composition with the reactive composition to produce a curing layer of composition involves curing at reduced deblocking temperature, or an acid-base reaction not requiring heating, or an epoxy-amine reaction not requiring heating.
