Abstract
As a device used to paint a pattern such as a band, stripe or streak on the surface of an elongate and thin base material continuously supplied, a painting device is composed of at least a painting groove provided across the moving direction of the base material continuously supplied and having an opening formed along its both ends with a width wider than the width of the above-described base material in a manner not to be closed by the base material, a primary pipe communicated with the painted groove and a secondary pipe linked with the primary pipe, so that different kinds of paints are filled into the painting groove through the primary and secondary pipes to paint a pattern such as a band, stripe or streak over the whole surface of the base material in motion. With the opening formed at the both ends of the painting groove in the width direction with a width wider than the latter, it is possible to paint the wole surface of the base material through a single painting process without leaving unpainted areas. This structure prevents any area from being unpainted, eliminates a post-painting processing, and reduces cost and facilities.
