Abstract

A winder intended for compressing a fibrous mat 4 rolls the mat up on itself and wraps it so as to store it and transport it with a reduced bulk. The machine has two belts 1, 2 supported by two fixed rollers 9, 13 and two mobile rollers 14, 15. The tension of the belts and the position of the mobile rollers are managed by a computer. The winding speed and the admissible compression ratio without damaging the fibrous mat are better than with the winder of the prior art.
