Abstract
A folding appliance includes a rotatable folding blade cylinder for transporting a signature to be folded, and at least one folding blade that can rotated about a first axle inside the folding blade cylinder. That first axle is held on a carrier which, in turn, can be rotated about a second axle. The folding blade can extend out of the folding blade cylinder during the course of rotation of the folding blade cylinder. The carrier and the folding blade cylinder can be phase-displaced in relation to each other.
Claims26
A folding apparatus comprising:
- a rotatable folding blade cylinder adapted to convey a signature to be folded;
- a support in said folding blade cylinder;
- a rotatable support shaft connected to said support and supporting said support for rotation in said rotatable folding blade cylinder;
- a support drive gear connected to said support shaft;
- at least a first folding blade shaft supported on, and spaced from said support for rotation with respect to said support;
- a folding blade carried by said folding blade shaft, said folding blade being extendable out of said folding blade cylinder in response to rotation of said support and said folding blade shaft;
- a cutting blade cylinder cooperating with, and driving said folding blade cylinder;
- means for phase-shifting said support and said folding blade cylinder relative to each other wherein said rotation of said folding blade cylinder and of said support are coupled, with a variable phase, to a rotation of said cutting blade cylinder;
- a differential gear assembly coupling said support drive gear and said cutting cylinder;
- and
- a differential gear drive connected to said differential gear assembly.
