  • Publication number: 20120223172
    Abstract: A twin and multiple motor paper shredder. Each of the motor relays power through respective gear assembly to the first rotary cutter. Each motor operates at a lower power output and have simpler specification than the conventional motor systems. However, when in combine use, the power output from two or more smaller motor are greater than one single larger motor system and the cost are lower. In this way, manufacturer is able to reduce the production cost, and at the same time, increase the stability and reliability of the paper shredder.
