The apparatus comprises: A. a folding station, comprising: 1) a removable platform, as the bottom of the folding station, to which each article is sequentially delivered; and 2) a folding means, which is in standby position and alongside the platform when an article is delivered onto the platform, for sequentially folding one portion of the article onto another portion thereof; and B. a loading assembly for sequentially loading each folded article into a carton which has a bottom which is aligned with and transversely spaced from the folded article on the platform, the loading assembly comprising: 1) a propulsion means for: a) in a first movement, pivotally operating the folding means to perform folding and transversely moving the folding means and therewith propelling the folded article into a carton, while moving the platform away from the folding station; and b) in a second movement, transversely returning the folding means and the platform to the folding station, and pivotally returning the folding means to the standby position; 2) a support and guide means for supporting the folding station, guiding the pivotal folding of the folding means, guiding moving of the platform, and guiding the transverse -ii- propelling of the folding means; and 3) a biasing means operatively cooperating with the propulsion means for returning the folding means and the platform to the folding station and pivotally returning the folding means to the standby position. Also disclosed is a method for sequentially folding and loading a plurality of thin, limp, sheet-type articles such as sandwich bags into a receptacle, comprising the following steps: A. sequentially delivering each article of a plurality of articles to a folding station having a removable platform and a folding member in standby postion; B. folding an article at least once with the folding member, whereby the folded article is transversely spaced from and aligned with the bottom of a receptacle therefor while supported by the platform; C. removing the platform from a folded article and simultaneously pushing the folded article toward the bottom by propelling the folding member; D. loading the folded article within the receptacle; E. returning the folding member to the folding station and to its standby position; and F. returning the platform to the folding station.
