ABSTRACT:
This invention provides an apparatus for folding sheet products, such as newspapers or the like, which includes a pair of cooperating fold rolls, a sheet supporting surface located above the fold rolls, a rotatable cage assembly carrying a tucker blade that tucks a sheet product into the nip of the fold rolls during each revolution of the cage assembly, and means mounted on the rotating cage assembly to substantially fill the space between the cage assembly and the sheet supporting surface during the time when the trailing edges of the folded product approach each other as the product is drawn through the fold rolls.
