ABSTRACT:
A spliced web and method for splicing web end portions together for minimizing splice-induced disturbance of a liquid composition continuously coated onto the face side of the spliced web during a coating operation. Splicing strips are applied overlying the face and opposite sides of the web end portions to form a sandwich, and the sandwich is subjected to heat and pressure. The splicing strip on the face side fuses with and impregnates the web end portions and forms slight trailing and leading ramp surfaces of gradually decreasing thickness which blend smoothly with the face side of the web for minimizing coating disturbances. The other splicing strip contains fibers which are embedded into or adhere to the opposite side of the web end portions to provide tensile strength to the spliced web.
