Abstract
A spiral wire and a method of manufacturing a spiral wire comprising adjacent spirals (1) positioned in pairs with their loops (1a) intermeshing to form rows of loops in the transverse direction of the wire, and link threads (2) inserted in the rows. The wire is subjected to thermal fixation by simultaneous stretching and heating thereof. In order to fix the loops axially immovably on the link threads, the link thread is formed by a core thread (3) provided with a coating (4) deformable at a lower temperature than the core thread. During the thermal fixation, the coating softens and is pressed from under the loops into the spaces between the loops and the coating is provided with grooves (5) for fixing of the loops without deformation of the core thread.
