Abstract
Folded cover sheets are conveyed seriatim from a first magazine into each of several parallel channels during each of a series of successive intervals. Such sheets are opened up on entry into the channels and are transported past one or more locations where they receive inserts which are supplied from one or more additional magazines, again in such a way that each additional magazine admits an insert into each channel during each of the successive intervals. The thus obtained groups of sheets are gathered into larger groups which are assembled into a continuous stream of partly overlapping groups.

- establishing a plurality of elongated paths having receiving ends and discharge ends;
- conveying a first sheet from the first source to the receiving end of each path during each of a series of successive intervals;
- transporting successive first sheets from the receiving ends toward the discharge ends of said paths;
- opening up the first sheets in the respective paths;
- admitting from the second source to each of said paths a second sheet during each of said successive intervals;
- and assembling each such second sheet with a first sheet in the respective path into a group of sheets during transport of the first sheets toward the respective discharge ends, said assembling step including introducing the second sheets between the panels of the respective first sheets.
