Abstract
A method and apparatus for folding sheet stacks in a web-fed rotary printing press is disclosed. The sheet stacks are severed from groups of paper ribbons and are conveyed by suitable conveying cylinders to spaced folding tables. Each folding table is provided with rotating folding blades and cooperating driving folding roller pairs. Each folding table is further provided with a pulse absorber assembly having a plurality of stop rods or bars which are positioned to contact the leading edge of each group of sheet stacks to halt the motion of the stacks on the folding tables. The halted sheet stacks are then folded. A suitable drive assembly for the pulse absorber is also disclosed.
