Abstract
This invention relates to apparatus and a method by which a liquid is applied in desired configurations to a continuous web which travels at a relatively high rate. The liquid may be that which is applied by jets or the like. According to this invention after the liquid is applied to the web excess quantities of fusible powder material are applied to the web during travel thereof. Some of the powder material adheres to the liquid, and powder material which does not adhere to the liquid is removed from the web prior to heating of the web to dry the liquid and to fuse the powder material. The liquid which is applied to the web in desired configurations may be a clear or colorless liquid, such as water or the like. The liquid may be a water-base ink or the like. The powder material applied to the wet configurations provide desired color or aesthetic qualities or protective qualities to the configurations and to the web.
