Abstract

A distinctive method and apparatus (20) for accumulating different types of individual articles (28) can include a delivery device (132) which provides an initial-plurality (134) of an initial-type of individual articles. At least a first-accumulator mechanism (142) can be automated to provide a first-plurality (144) of a first-type of individual articles. The first-type of articles differ from the initial-type of articles, and at least a first-transport device (146) can move the first-plurality of articles to a first-packing location. Additionally, an automated assembly mechanism (136) can be configured to operatively combine the first-plurality (144) of articles with the initial-plurality (134) of articles.
