Abstract
A manufacturing method includes: a step for producing a batt of fibers, elongated in a longitudinal direction, by batting with interlacing of the fibers, a step for passing the batt of fibers, in the longitudinal direction, through a loop-forming device having a set of rotary discs and stationary loop-forming elements, so as to generate undulations, and, following the passing step, a step for bringing the batt of fibers onto a conveyor equipped with brushes, and accumulating the undulations in the brushes so as to achieve a predetermined density.
