Abstract: A method of manufacturing a carpet pad and the apparatus for the same are shown. A frame is provided to which is mounted a conveyor belt. The conveyor belt feeds a first liner sheet along a conveyor path from a forward end to a rearward end. A foam spray assembly is connected to an uncured polymeric foam supply having a spray nozzle mounted adjacent to the forward end of the conveyor path. The spray nozzle dispenses uncured, resilient polymeric foam as a generally uniform layer on a surface of the first liner sheet. A second conveyor belt mounted to the frame is located along the conveyor path and spaced apart from the second conveyor belt a selected distance. The second conveyor belt is parallel to the first conveyor belt and feeds the second liner sheet along the conveyor path so that the second liner sheet is positioned over the layer of foam.
