Abstract

The present application relates to methods for the manufacturing of improved packaging for compressed mineral wool insulation blowing wool fibers, as well as methods for the introduction and distribution of the same.

First claim

The invention claimed is:

1. A method of introducing mineral fiber blowing wool from a package of compressed mineral wool insulation loose blowing wool fibers into a blowing machine comprising:
compressing uncompressed mineral wool insulation blowing wool fiber with a press along a single axis to produce a compressed bulk of blowing wool fibers;
retaining the compressed bulk of blowing wool fibers with at least one retainer to form the package,
removing the at least one retainer from the package and removing any enveloping film covering an upper surface of the blowing wool package; and
displacing mineral wool fibers from the upper surface of the package to an inlet of a blowing machine.

2. The method of claim 1 , wherein the compressed bulk of blowing wool fibers is configured to expand substantially along a single expansion upon release of the at least one retainer.

3. The method of claim 1 , wherein the package is displaced vertically with respect to a fiber unloader which displaces mineral wool fiber from the upper surface of the package to an inlet of a blowing machine.

4. The method of claim 1 , wherein the at least one retainer comprises one or more securing straps arranged around the package.

5. The method of claim 1 , wherein the package comprises a flexible plastics film enveloping the blowing wool fibers.

6. The method of claim 5 , wherein the flexible plastics film enveloping the blowing wool fibers comprises: (i) an upper portion covering the upper surface and at least an upper part of lateral surfaces of the package; and (ii) a separable lower portion covering a lower surface and at least a lower part of the lateral surfaces of the package.

7. The method of claim 6 , where the flexible plastics film enveloping the blowing wool fibers further comprises: (iii) a middle portion covering the lateral surfaces and partially overlapping a part of the upper portion and a part of the lower portion.

8. The method of claim 1 , wherein the blowing wool fibers are glass wool fibers.

9. The method of claim 1 , wherein the compressed mineral wool insulation has a density of at least 80 kg/m 3 .

10. The method of claim 1 , wherein the package has a mass of at least 80 kg.

11. The method of claim 1 , wherein the package has a length of at least 0.9 m, a width of at least 0.75 m, and a height of at least 0.8 m.

12. The method of claim 1 , wherein lateral surfaces of the package are substantially planar.

13. The method of claim 1 , wherein the mineral wool insulation blowing wool fibers are selected from loose blowing wool fibers, loose blowing wool flocks and combination thereof.
