Abstract
An apparatus and method for applying thin film polymer labels to small cylindrical articles such as dry cell batteries without label mismatching is disclosed. A label transport drum is rotatably mounted on a frame. Cut labels are supplied to the surface of the label transport drum as the drum is rotated. An adhesive is applied onto the area adjacent the leading edge of the label while the label is moving with the drum, and a solvent is applied onto an area adjacent the trailing edge of the label. Cylindrical articles are conveyed in tangential spinning engagement with the label transport drum and into rotative engagement with the adhesive on the leading edge of the label so as to transfer the label onto the article as the label is moved into engagement with the rotating article. A pressure plate imparts pressure against selected sides and ends of the article during wrapping to prevent mismatching of the label as the label wraps around the article. A seam is formed at the overlap of leading and trailing edge portions. The pressure plate has an article engaging surface positioned adjacent the surface of the drum. The camber of the plate may be varied relative to the articles conveyed…
