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. This differential movement gives a micro-adjustment to the platform and the roll relative to the surface of the vacuum drum.
