Abstract:
A device for folding a sheet material comprising:a folding device having a plurality of surfaces and adapted to longitudinally fold a sheet material drawn across said folding device, said folding device comprising a top plate having a first surface and a first creasing mechanism coupled thereto, the top plate and first surface extending in a first plane, the first creasing mechanism configured to form a pressurized nip with the first surface; a second guide plate having a second surface and a second creasing mechanism coupled thereto, the second guide plate and second surface extending in a second plane, the second creasing mechanism configured to form a pressurized nip with the second surface, the second guide slate and second surface positioned so that the second plane is not parallel with the first plane; a side plate having a third surface, the side plate and the third surface extending in a third plane, the side plate configured to join the top plate and the second guide plate together, a guide opening provided at a juncture of the top plate, the second guide plate, and the side plate, wherein when sheet material is drawn across the first surface of the top slate in the first plane and the side surface of the side plate in the third plane, a portion of sheet material extends into the guide opening and the sheet material emerges onto the second surface of the second guide plate in the second plane opposite the first and third surfaces in a folded configuration.
