Abstract
A folding device for use with a rotary printing press includes a folding-jaw cylinder and a folding blade cylinder. The folding blade cylinder is movable with respect to the folding-jaw cylinder between a working position where it cooperates with the folding-jaw cylinder and a rest position where it is moved away from the folding-jaw cylinder.
Claims24
A folding blade apparatus comprising:
- at least one folding jaw cylinder;
- a first folding blade cylinder adapted to work with said folding jaw cylinder in a first working position defined by said first folding blade cylinder and said folding jaw cylinder;
- a second folding blade cylinder adapted to work with said folding jaw cylinder in a second working position defined by said second folding blade cylinder and said folding jaw cylinder;
- means for displacing said second folding blade cylinder between said second working position and a rest position, said second folding blade cylinder being moved away from said folding jaw cylinder in said rest position;
- and
- at least first and second pairs of folding jaws on said folding jaw cylinder, said first folding blade cylinder working with said first pair of folding jaws and said second folding blade cylinder working with said second pair of folding jaws when said second folding blade cylinder is in said second working position.
3 more elements
A folding apparatus comprising:
- at least one folding jaw cylinder;
- a folding blade cylinder adapted to work together with said at least one folding jaw cylinder;
- means for displacing said folding blade cylinder between a working position and a rest position, said folding blade cylinder working with said folding jaw cylinder only in said working position of said folding blade cylinder;
- an intermediate space between said at least one folding jaw cylinder and said folding blade cylinder when said folding blade cylinder is in said rest position;
- and
- a folded signature guidance system positionable in said intermediate space only when said folding blade cylinder is in said rest position.
3 more elements
A folding blade apparatus comprising:
- at least one folding jaw cylinder;
- a folding blade cylinder adapted to work together with said at least one folding jaw cylinder when said folding jaw cylinder is in a working position;
- means for displacing said folding blade cylinder between said working position and a rest position in which said folding blade cylinder is moved away from said folding jaw cylinder;
- and
- means for mechanically moving said folding blade cylinder out of said working position and to said rest position in response to a sensed voltage drop in the folding blade apparatus.
2 more elements
A folding apparatus comprising:
- at least one folding jaw cylinder;
- a first folding blade cylinder;
- a first electric motor, said first electric motor driving both said at least one folding jaw cylinder and said first folding blade cylinder;
- a second folding blade cylinder;
- and
- a second electric motor driving said second folding blade cylinder, said second folding blade cylinder being driven by said second electric motor independently of said first folding blade cylinder.
