Abstract
A method and system for the production of a web the fibers of which form a mean angle with respect to the longitudinal direction. The method and system include the passage of the web through a looping system, the passing of the web over a conveyor provided with brushes, the deposition of a first pre-needle-punched layer of fibers over the accumulated undulations, the assembling of the accumulated undulations with the first pre-needle-punched layer by needling, the assembling of the structure with a second pre-needle-punched layer of fibers, so as to obtain a sandwich structure, and the separation of the sandwich structure so as to obtain two symmetrical velour coverings. The web is a card web with a mean angle between 5 and 10° and an area density between 80 and 120 g/m. The method includes a longitudinal drawing of the web, with a stretch ratio between 1.5 and 2.
