ABSTRACT:
A continuously moving web pressure-sensitive labeler applies pressure-sensitive labels to articles moving in a given direction past a label applying station. The labels are initially carried by the moving web and the labeler includes a label applying mechanism such as a peel plate and a vacuum drum for stripping labels from the moving web and delivering the stripped labels in the given direction onto articles as they pass the label applying station in the given direction. The labeler also has mechanism which generates a timing signal for timing the placing of labels in register on the label applying mechanism. In a first embodiment, the timing signal generating mechanism includes an encoder driven by the drum and also includes a rotary vacuum valve. In a second embodiment, the labeler includes a conveyor for carrying articles past the label applying station and a timing screw for orienting articles on the conveyor in evenly spaced single file manner, and the mechanism for generating a timing signal includes an encoder driven by the timing screw.
