Abstract

A machine winds a fibrous mat on itself after compressing it. The winding machine has two bands which each embrace about half the circumference of the roll being formed. The machine also includes a plate intended to keep the mat compressed. This plate and, if appropriate, a device for causing compression of the mat are movable and advance downstream as the fibrous mat is wound. In a variation, the compression device is fixed and the plate is lengthened.
