A method and apparatus for producing a fibrous material product by advancing a mat of glass fibers arranged in laminations extending at least substantially parallel to opposite major surfaces of the mat along a gap extending between successive driven conveyors which engage the opposite major surfaces of the mat to control the advance of the mat along the gap, and driving the conveyors at progressively slower speeds along the gap so that the laminations are deformed in at least two separate stages into a reorientation in which at least a major portion of the laminations extend across the thickness of the mat. The resulting product has an improved compression strength.

Process and apparatus to crimp fibres

Apparatus for compressing and packaging articles, e.g. insulation batts, comprises a bomb bay door arrangement for receiving the articles in succession and depositing the articles in a first position in successive batches each comprising a stack of the articles, a compression chamber, a movable support for displacing the batches in succession from said first position to a second position in the compression chamber, a lifting fork for displacing a first one of the batches from the second position to a third position in the compression chamber to allow the displacement of the next succeeding batch from the first position to the second position, a vertical ram for compressing the first batch and the next succeeding batch together in the compression chamber, and a horizontal ram for discharging the compressed articles through a bagging snout for applying a bag to the compressed articles.
