Claims12
A device for returning folded paper at, near or around a paper input end of a paper folding apparatus comprising:
- a frame comprising opposing side plates;
- a first conveyer system including a first endless conveyer belt, a first driven roller, and at least one freely rotatable guide roller, wherein said first conveyer belt is wrapped around said first driven roller and said at least one freely rotatable guide roller, wherein said first driven roller is rotatable in a counter-clockwise direction thereby driving said first endless conveyer belt in a first direction, and said at least one freely rotatable guide roller guides and supports said first conveyer belt;
- and
- a second conveyer system including a second endless conveyer belt, and at least two freely rotatable guide rollers, wherein said second conveyer belt is wrapped around said at least two freely rotatable guide rollers, said at least two freely rotatable guide rollers rotate in a direction opposite to said first driven roller, and said second conveyer system is located underneath said first conveyer system;
- wherein said guide rollers extend between said opposing side plates of said frame, and wherein said first driven roller is adapted to be mounted to the existing frame of a paper folding machine to guide said folded paper back to said input end.
2 more elements
A paper folding apparatus comprising:
- a frame;
- a sheet feeder supported by said frame for delivering sheets of paper to a sheet folding mechanism;
- a paper folding mechanism located downstream from said sheet feeder;
- a device for returning folded paper to said input end of said sheet feeder, said device disposed underneath said sheet feeder and folding mechanism, wherein said device comprises a frame comprising opposing side plates, a first conveyer system including a first endless conveyer belt, a first driven roller, and at least one freely rotatable guide roller, wherein said first conveyer belt is wrapped around said first driven roller and said at least one freely rotatable guide roller, wherein said first driven roller is rotatable in a counter-clockwise direction thereby driving said first endless conveyer belt in a first direction, and said at least one freely rotatable guide roller guides and supports said first conveyer belt, and a second conveyer system including a second endless conveyer belt, and at least two freely rotatable guide rollers, wherein said second conveyer belt is wrapped around said at least two freely rotatable guide rollers, said at least two freely rotatable guide rollers rotate in a direction opposite to said first driven roller, and said second conveyer system is located underneath said first conveyer system, wherein said guide rollers extend between said opposing side plates of said frame, and wherein said driven roller is adapted to be mounted to the existing frame of a paper folding machine;
- and
- means for driving at least one of said sheet feeder, said folding mechanism and said device for returning folded paper.
