Abstract
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.
