A jogger for a signature feeder includes a back stop disposed at a first side of a hopper of the feeder and a flexible jogging element disposed at a second side of the hopper opposite the first side. As a stack of signatures is formed in the hopper, the flexible jogging element is oscillated in a lateral direction so as to periodically bend the flexible jogging element against the stack of the signatures and form a pushing zone and a vibrating zone in the hopper. The vibrating zone is below the pushing zone, and the vertical lengths of the pushing and vibrating zones are a function of the height of the stack of signatures. The signatures in the pushing zone are urged against the back stop by the flexible jogging element so as to register the signatures as the stack is formed, and the signatures in the vibrating zone are vibrated by the flexible jogging element so as to improve the registration of the signatures in the stack. The jogging action adjusts automatically to the height of the stack and the characteristics of the signatures.

A lap separator system opens a sheet in a pocket traveling in a direction at a given speed, the pocket having forward and rearward walls pivotally connected to one another and, together, defining a sheet-receiving opening, and includes a moveable separator carrier, a separator connected to the carrier, the separator carrier conveying the separator in the transport direction along the pocket at a speed greater than the given speed, and the separator sequentially contacting the rearward wall, the sheet in the pocket, and then the forward wall and sequentially releasing the rearward wall, at least a portion of the sheet in the pocket, and then the forward wall. The system can be part of a sheet-collating machine having a conveyor, a sheet feeding device, and many pockets. A method for opening a sheet includes displacing the separator to sequentially contact and release the walls and sheet.
