Extremal Black Holes and Attractors

A tag placement apparatus useful for placing a tag or label into communication with a container. The tag placement apparatus includes at least one tagging head having a linear slot in which a cam portion of a tag placement arm assembly reciprocally travels in response to a cylinder stroke to which it is attached. The tagging apparatus further includes an encoder for translating the roller rotation of a conveyor assembly into belt position and travel which in turn regulates the speed in which the reciprocal movement of the tag placement arm operates during use.
