Web material having spliced joints and a method for coating a web material having spliced joints

Abstract

A web material, which is able to avoid air entrainment, comprises a surface for applying at least one layer of coating material. The web material has at least one splicing tape for connecting a preceding web and a succeeding web with respect to a transport direction of the web material. The splicing tape defines a trailing edge on the surface of the succeeding web. After the trailing edge of the splicing tape a thin layer with limited width and a rough surface is formed. Additionally, there is a method for continuous coating a web material having at least one spliced joint. The method comprises the steps of: applying a splicing tape on one surface of a preceding web and succeeding web, with respect to a transport direction of the web material, and thereby connecting said preceding web and said succeeding web; providing an additional layer with limited width and thereby defining a rough surface on the surface of the succeeding web immediately after the splicing tape; and applying at least one layer of continuous coating to the surface of the web material.
