  • Varying the drop of sheets into a hopper
    Patent number: 4180259
    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.
