Abstract
A filling product comprising a plurality of narrow, elongated strip segments is provided. Each strip segment has a plurality of transverse folds and substantially planar portions between adjacent folds. At least some of the strip segments comprise at least two layers of material, including a first layer comprising a first material and a second layer comprising a second material, wherein the second material is different in composition from the first material. Corresponding methods of producing such filling products are also provided.
Claims15
A filling product comprising a plurality of narrow, elongated strip segments which are intertwined and interlocked with each other, each strip segment comprising a plurality of transverse folds and substantially planar portions between adjacent folds, such that at least some of the strip segments comprise at least two layers of material, and the multi-layered strip segments comprise:
- a first layer comprising a first material;
- and
- a second layer comprising a second material, wherein the second material is different in composition from the first material.
A method of producing a filling product, the method comprising the steps of:
- providing a plurality of narrow, elongated strip segments, each strip segment comprising a longitudinal length dimension and a transverse width dimension, and at least some of the strip segments comprise at least two layers of material, including a first layer comprising a first material and a second layer comprising a second material which is different in composition from the first material;
- and
- advancing each strip segment in a first direction generally parallel with the length dimension, and sequentially folding each strip segment generally on itself during the advancing so that the strip segment forms a plurality of transverse folds and substantially planar portions between adjacent folds.
