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.
Claims14
A winder for winding up a flexible band comprised of a compressed fibrous mat, comprising:
- first and second driven belts forming a cavity into which the band may be fed to wind the band;
- and
- means for feeding the band into the cavity in a feeding direction to wind said band, including means for compressing the band prior to the band entering the cavity, wherein said compressing means comprises elements forming planes moving toward the cavity and having a spacing which decreases toward the cavity,
- wherein said driven belts are sized and supported such that said first and second driven belts conform to the shape of a band being wound in the cavity and provide a substantially constant pressure over substantially the entire periphery of the band in the cavity.
