Abstract
A structure for use in industrial fabrics such as paper machine clothing and engineered fabrics. The structure is a bicomponent extruded elastomeric netting or mesh having a high degree of both compressibility under an applied normal load and excellent recovery (resiliency or spring back) upon removal of that load.
Claims40
A method for forming an article comprising a bicomponent extruded mesh, the method comprising:
- extruding a first layer of parallel strands in a machine direction;
- co-extruding a second layer of parallel strands on one side of the first layer, the second layer's strands running in a cross-machine direction and
- comprising elastomeric strands;
- and
- co-extruding a third layer of parallel strands on an opposite side of the second layer as the first layer, the strands of the third layer running in a same direction as those of the first layer,
- wherein the first, second, and third layers are co-extruded together such that the strands in the first layer are positioned or aligned within respective spaces between strands in the third layer,
- wherein the first, second, and third layers form a bicomponent extruded mesh having a desired thickness,
- wherein under a compressive load the second layer stretches to enable the strands of the first and third layers to nest between each other such that the strands of the first and third layers are substantially coplanar,
- and wherein upon release of the compressive load, elasticity of the second layer causes the first and third layers to spring back returning the structure to substantially the desired thickness.
