  • Sieve cleaner for a plansifter
    Patent number: 6336557
    Abstract: A sieve frame for a plansifter has a sieve covering, a bottom, and at least one sieve cleaner including a foot and a plurality of cleaning heads. The cleaning heads may have a brush-like or nubby configuration. The cleaning heads are configured to move erratically on the bottom in response to a vibrating movement of the sieve frame. At least a part of the foot closest to the cleaning heads resiliently supports the sieve cleaner such that the cleaning heads are under an elastic intial tension against the sieve covering.
