Abstract: A moistening apparatus for moistening a form sheet. The apparatus includes a body having a trough in its top portion and a reservoir in its lower portion. A capillary tube connects the trough with the reservoir and a roller co-extensive with the trough, is mounted so that its lower portion is substantially surrounding by the trough.

Abstract: A labeling system where a cylindrical vacuum drum carries plastic labels at spaced intervals on its surface and a solvent applying gravure roll is held at a specific spacing from the drum and labels so that the labels will receive the solvent when they pass the rotating roll. The gap between the drum and the roll must be carefully controlled in order to be assured that the solvent is properly transferred. The gap is controlled by a fine adjustment of the platform on which the roll is mounted relative to the drum by a threaded rod moving a tapered surface of a reciprocable member in contact with a stop block mounted on the platform. The threaded rod threads through a stationary bracket and turns a shaft that threads into the member. The member is prevented from rotation so that rotation of the rod moves the member in one direction while rotation of the shaft moves the member in the opposite direction.

Abstract: The present invention relates to a method for forming a uniform, extremely thin film on the surface of plastics molded articles, films, sheets, synthetic paper, fibers, metal, and other objects, the film containing an anti-static agent, anti-fogging agent, anti-corrosive agent, mildewproofing agent, and the like.
