Abstract

An apparatus for manufacturing a thermal and/or acoustic insulation product based on mineral wool, including: a first line for production of first mineral fibers, including at least one fiberizing member; a second line for production of second mineral fibers, including at least one fiberizing member and a cross-lapping device; and a cross-lapping device configured to deposit the second mineral fibers onto the first mineral fibers by cross-lapping. The apparatus can manufacture a thermal and/or acoustic insulation product with improved thermal and/or acoustic properties.

First claim

The invention claimed is:

1. An apparatus for manufacturing a thermal and/or acoustic insulation product based on mineral wool, comprising:
a first line for production of first mineral fibers, comprising at least one fiberizing member;
a second line for production of second mineral fibers, comprising at least one fiberizing member and a cross-lapping device,
the cross-lapping device being configured to deposit the second mineral fibers onto the first mineral fibers by cross-lapping.

2. The apparatus as claimed in claim 1 , wherein the first production line and/or the second production line each comprises at least two fiberizing members, different members on each production line being arranged in series.

3. The apparatus as claimed in claim 1 , further comprising a crimping machine, positioned between the at least one fiberizing member of the first production line and the cross-lapping device, configured to crimp the first mineral fibers before they are overlaid by the second mineral fibers, and/or downstream of the cross-lapping device, configured to crimp the first mineral fibers overlaid by the second mineral fibers.

4. The apparatus as claimed in claim 1 , further comprising a drying oven configured to receive the first mineral fibers overlaid by the second mineral fibers.

5. The apparatus as claimed in claim 1 , wherein each fiberizing member of at least one of the production lines comprises:
an internal centrifugation spinner configured to rotate about its substantially vertical axis of symmetry, a peripheral band of which is perforated by a plurality of orifices;
an annular burner configured to perform gaseous stretching at high temperature at an exit from the orifices of the centrifugation spinner.

6. The apparatus as claimed in claim 5 , further comprising:
a blowing ring configured to channel the fibers towards a first or second conveyor belt.

7. The apparatus as claimed in claim 6 , further comprising:
a gluing ring configured to spray a binding compound onto the fibers before they reach the first or the second conveyor belt.

8. The apparatus as claimed in claim 1 , wherein the cross-lapping device is a vertical or horizontal cross-lapping device.

9. The apparatus as claimed in claim 1 , wherein the first and second production lines are substantially perpendicular to each other.

10. A method for manufacturing a thermal and/or acoustic insulation product based on mineral wool, comprising:
manufacture of first mineral fibers on a first production line by at least one fiberizing member;
manufacture of second mineral fibers on a second production line by at least one fiberizing member;
passage of the second mineral fibers into a cross-lapping device;
deposition by cross-lapping of the second mineral fibers onto the first mineral fibers by the cross-lapping device.

11. The method as claimed in claim 10 , further comprising passage into a crimping machine of the first mineral fibers on their own and/or of the first mineral fibers overlaid by the second mineral fibers.

12. The method as claimed in claim 10 , further comprising passage of the first mineral fibers overlaid by the second mineral fibers into a drying oven.
