Abstract: A slicing blade for a slicing machine includes a center region connectable to a source of rotary power to be rotated about an axis, and a cutting edge region driven into rotation by the center region and having a discontinuous cutting edge. The discontinuous cutting edge is formed by a plurality of notches along the cutting edge region. The notches are formed by serrations arranged on at least one face of the cutting edge region. The notches can have a consistent pitch between adjacent notches. The notches can be arranged continuously around the cutting edge. The notches can alternately be arranged in sections, the sections spaced apart around the cutting edge region.

Abstract: Apparatus for shaping batts of loosely compacted fibrous material into individual panels of specific shapes. A pair of rolls rotating in opposite directions, with high-pressure air blown from the surface of one roll to the other in a spaced apart nip area is used to carry out the method.

Abstract: Method for shaping and/or cutting batts of loosely compacted fibrous material into individual panels of specific shapes without ragged edges or hard-cut edges. A pair of rolls rotating in opposite directions, with high-pressure air blown from the surface of one roll to a recessed portion of the other in a spaced apart nip area used to carry out the method.
