Abstract
Abstract There is disclosed a tag stacker and tag stacking method for taking tags from an output device such as a printer and stacking them in a stack. Tags are inputted one-by-one into the stacker and are moved from a generally horizontal orientation to a generally vertical orientation in a stack. Tags are fed one-by-one into the stack in a hopper, the tags are tamped to settle them in the hopper and the stack is advanced by a conveyor as the stack builds. A side of the stack is guided by an adjustable side guide.
