  • Patent number: 6605027
    Abstract: A folder in a signature-processing machine has a transfer cylinder and a folding cylinder. The two cylinders are mounted to be rotatable in relative counter-rotation at a substantially equal peripheral speed. They form a nip through which a signature is transported. The signature is taken up by the folding cylinder at a folding location between its leading edge and its trailing edge. In order to reduce the formation of dog-ears and crumpling when the signature tail is ripped away from the transfer cylinder, there is provided a fold-off guide at the exit side of said nip. In order to adapt for speed changes of the folder, and to allow for the fold-off guide to change its shape in synchronicity with each signature, the fold-off surface of the guide is movably disposed. The fold-off guide, in a simple embodiment, may be a flexible plate. In a dynamically varying embodiment, the fold-off guide may be cam or an eccentric with or without the intermediary of an endless belt which travels with the folding cylinder.
