1. A method for splicing an upstream section and a downstream section of a multi-layered laminated sheet material wherein each section of the material comprises at least three layers each having first and second surfaces and wherein the at least three layers comprise first and second outer layers and at least one inner layer located between the first and second outer layers, comprising the steps of
a. splicing together the upstream and downstream sections of both the first and second outer layers with a splicing material;
b. removing the first outer layer from the multi-layered laminated sheet material to expose a surface of an inner layer;
c. splicing the upstream and downstream sections of the exposed inner layer with a splicing material; and
d. applying a replacement first outer layer to the exposed surface of the inner layer.
