Device for separating front part and back part of a folded sheet in sheet receiving pockets and method for carrying out such separation

摘要

The lap separator system has a movable separator carrier adapted to convey at least on separator in the transport direction along the pocket (10) at a speed greater than the given speed. The separator is adapted to sequentially contact the rearward wall of the pocket, the sheet in the pocket, and then the forward wall of the pocket. The separator is also adapted to sequentially release the rearward wall, at least a portion of the sheet in the pocket, and then the forward wall. Independent claims are also included for the following: (a) a sheet-opening system; (b) a sheet-collating machine; and (c) a method for opening a sheet within at least one sheet-receiving pocket of a sheet-collating device.
