A method and an apparatus for stacking serially advancing parallel streams of blanks, such as corrugated paperboard blanks, by serially advancing such parallel streams in which there are spaces between pairs of such blanks in each of the streams but no spaces between the blanks of the pairs, creating spaces between the blanks of each pair during advance, stopping the advance of the blanks one after the other, and guiding succeeding spaced blanks one on top of the other to form a stack of blanks from each stream.
