ABSTRACT:
A method and apparatus for making a polymeric coated fabric layer is provided, the method comprising the steps of providing a fabric layer having warps and fills initially woven at a certain angle relative to each other, then changing the certain angle to another angle by stretching the fabric layer in one direction thereof whereby the fabric layer is in an altered condition thereof, disposing a liquid polymeric coating on at least one side of the fabric layer while the same is in the altered condition, doctoring the coating, further stretching the fabric layer in the 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 fabric layer in substantially the altered condition thereof, the step of doctoring the coating taking place after the step of further stretching the fabric layer and the step of further stretching the fabric layer taking place after the heating unit has dried the coating to at least a degree thereof that the further stretching of the fabric layer causes an outward thickening of tne coating on the one side of the fabric layer.
