Abstract
A method of producing a packing product includes the steps of feeding at least one sheet of material in a first direction; cutting the at least one sheet of material into a plurality of strips; the cutting being performed by rotating two sets of alternating, overlapping cutting discs; the feeding of the at least one sheet of material being between the two sets of cutting discs; advancing each of the strips by the rotating of at least an outer surface of a corresponding one of the cutting discs as the outer surface moves in the first direction; restricting each strip from continued advancing in the first direction; and sequentially folding each of the strip means by the restricting in opposition to the advancing. There is included apparatus and means for producing the packing product. Additionally, the resulting packing product includes a plurality of narrow, elongated strips of material; the material having a natural resilience; and each of the strips including a plurality of transverse folds against the natural resilience to form a longitudinally compressed strip element.
