Abstract
Signatures fresh from the printing press are fed in a shingled stream toward and then dropped one by one into a hopper which may feed a gathering chain. The signatures are 'broken' (unstuck) by first stacking them edgewise on horizontal support, shingling them in a constant stream by an unusual form of suction feed, bending the shingled stream and thereafter cascading the stream into the hopper.
