CA 2445096

Carpet segments or other recycled materials are shredded, then layered transversely across a slow moving conveyor system, to form a wide, thick, low density belt of fibers. This fluffy belt is then compressed to generate a fibrous mat which is subsequently needle punched. A polymeric binder is then applied to the needle punched mat and the impregnated mate is compressed and the polymeric binder cured to produce a hardened wood-like product.

L'invention concerne la fabrication d'une ceinture à faible densité, large et épaisse, à partir de segments de tapis ou autres matériaux recyclés déchiquetés puis mis en couches transversales sur un système transporteur à déplacement lent. La ceinture pelucheuse résultante est ensuite comprimée en un mat fibreux qui est aiguilleté. Un liant polymère est ensuite appliqué au mat aiguilleté, et le mat ainsi imprégné est alors comprimé, puis le liant polymère traité, pour fabriquer un produit durci semblable à du bois.
