Abstract
A structure for use in a compressible resilient pad. The structure contains both axially elastomeric strands and relatively inelastic strands co-extruded in various patterns. The structure has a high degree of both compressibility under an applied normal load and excellent recovery (resiliency or spring back) upon removal of that load.
Claims28
A method for forming a compressible resilient pad, the method comprising:
- forming a bicomponent extruded mesh comprising the steps of:
- extruding a first layer of parallel strands in a longitudinal direction (LD);
- co-extruding a second layer of parallel strands on one side of the first layer, the second layer's strands running in a transverse direction (TD) 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 and running in the same direction as those of the first layer,
- wherein the first, second, and third layers are co-extruded at substantially the same time such that the strands in the first layer are positioned or aligned within a space between strands in the third layer, and
- wherein materials for the first, second, and third layers are selected such that the layers are bonded together as a result of being co-extruded,
- wherein the strands in the LD are more inelastic than the strands in TD.
