1. Field of the Invention
The present invention relates to a paper shredder with a pair of cutting rollers and individual strippers mounted on support rods. The strippers extend essentially from the lower and upper outer sides of the cutting mechanism between the cutting disks to the respective roller body. The strippers preferably have crowned stripper portions.
2. Description of the Related Art
The configuration and arrangement of stripper elements for paper shredders operating according to the cutting roller principle have undergone intensive development in the past decade. In addition to the further development of the stripper elements arranged between the cutting disks, solutions have been proposed increasingly in recent years in which additional stripper elements are provided directly on the outer diameter of the cutting disks.
These solutions prevented that cut particles stuck between strippers and cutting disks, which over time resulted in increased friction and a higher ,contact pressure and frequently led to blockage of the cutting mechanism. However, these known solutions are more complicated and expensive and, when the installed power remained the same, a reduction of the available cutting power occurred.
