ABSTRACT:
The present invention relates to a method and apparatus for the production of fibrous insulation, especially relatively thick fibrous insulation. Previously some relatively thick insulation has been produced through lamination techniques using a plurality of insulation layers, which possibly included the use of a continuous fibrous hinge as an alignment aid during lamination. However, proper alignment using a continuous hinge is difficult and leaves an objectionable bulge of fibrous material. The present invention eliminates the fibrous bulge of the prior art and provides a more accurate means by which to substantially accurately align the layers of fibrous insulation. A fibrous blanket of insulation is slit by means of a notched cutting blade to provide a plurality of fibrous hinges or fibrous pillars connecting a plurality of fibrous batts whereby upon the application of an adhesive to one or more of the fibrous batts, another of the batts may be folded about the hinges onto the adhesive covered batt and laminated to form the relatively thick insulation product.
