A machine for forming a slug of edgewise supported flat articles. The machine includes a table above which the articles of the slug are accumulated. Paired conveyor belt means advance the articles in shingle fashion past an edge of the table. One of the belt means has a portion parallel to and at substantially the level of the table for rapidly advancing lower edges of the articles away from the other of the belt means and onto the table. An upper backstop supports the articles on the table and on said belt portion. The articles are urged toward the backstop means to form the slug. The upper backstop is advanced from said edge of the table as the slug of articles forms on the table. Control of the slug is transferred from the upper backstop to an auxiliary backstop. Upright fingers are advanced into engagement with a last article in the slug so that the slug is held between the fingers and the auxiliary backstop. The fingers and the auxiliary backstop are advanced in unison to advance the stack to a discharge station.
