Abstract:
1. A method for forming completed packs containing a desired number of folded sheets formed in a stacking region below a pair of folding rolls along a sheet path extending through a nip between the pair of folding rolls by a continuously flowing sheet stream of folded sheets issuing downstream from the pair of folding rolls along the sheet path and having adjacent panels forming successive folds opening alternately in opposite directions substantially transversely to the sheet path, the method comprising: inserting a pair of count fingers into successive oppositely opening folds to initiate each new pack, and moving the count fingers in a downstream direction while continuing to at least partly build the next pack on upstream surfaces of the count fingers; and then retracting the count fingers by moving them substantially linearly oppositely from one another outward from the sheet path to release the at least partly completed pack for movement downstream along the sheet path; and wherein: the method further comprising:
