ABSTRACT:
A method and apparatus for making a polymeric coated layer is provided, the method comprising the steps of providing a strand layer with the strands thereof disposed in a predetermined pattern, forming the strand layer to comprise a first substantially planar layer of strands disposed in superimposed relation with a second substantially planar layer of strands whereby the strands of the first layer are not woven with the strands of the second layer, disposing a liquid polymeric coating on the strand layer while the strands thereof are disposed in the pattern thereof, doctoring the coating, stretching the strand layer in one direction after the step of disposing the coating thereon, and drying the coating with a heating unit to at least a degree thereof that will hold the strands of the strand layer in substantially the pattern thereof whereby the coating effectively is the sole securement securing the strands of the first layer to the strands of the second layer and thereby imparts its flexible characteristic to the securement between the strands of the first and second layers. The step of doctoring the coating takes place after the step of stretching the strand layer and the step of stretching the strand layer takes place after the heating unit has dried the coating to at least a degree thereof that the stretching of the strand layer causes an outward thickening of the coating from the strand layer.
