  • Patent number: 5953782
    Abstract: Described is a cutting head for a pipe cleaning assembly. The cutting head has a cutting head housing and at least two cutting head blades pivotally supported at the cutting head housing in the manner of scissors and biassed into a spreaded normal position. The cutting blades are movable radially inwardly by the lateral application of force against the biassing action approximately until a position of coincidence. Such a cutting head adapts itself in an especially good manner to the grade of clogging of the respective pipe on account of the flexible support of the two cutting blades.
