Abstract
Strips of mineral fibers are brought into a space defined by three members operated by a movement which drives the coiling of the strip. The third of these members, the compressor roller, is operated at a rotational speed which is a function of a predetermined program while introducing as parameters the length of the strip which has already been coiled and the speed of the feeding conveyor of the strip. The rolls obtained are cylindrical and there are no overcompressed zones.
