摘要：A device for the delayed piling of sheets in a delivery mechanism of a sheet fed printing press to provide time for the insertion of a temporary receiving tray as a filled pile board is removed and replaced by an empty pile board. A buffer storage device is located immediately above the support for the receiving tray for intercepting sheets entering the receiving space. The buffer storage device includes a front edge support for supporting the front edge of a sheet and a rear edge support for supporting the rear edge of the sheet. At least the rear edge support, which occupies a normal horizontal position, has a hinge mounting but is lightly counterbalanced so that the first few sheets, upon making a pile change, are intercepted providing a time delay for insertion of the receiving tray, but with the accumulated weight of the first few sheets being sufficient to overcome the counterbalancing force so that the intercepted sheets, following the time delay, are automatically dumped as a group upon the tray. In the preferred form of the invention the rear support is of dog-leg cross section having a horizontal support leg and a generally vertical counterbalancing leg with a pivot axis between them. Also in the preferred embodiment a sheet brake assembly is mounted on the frame adjustably positionable for accommodating sheets of different length, with the rear edge support being hinged to the subassembly for simultaneous adjusting movement therewith.
