The applied root head cleaner has a driving horizontal shaft with two basic flat elastic cleaning elements, tangentially fixed thereon, the free ends of which are linked with the shaft of the cleaner with the aid of flexible ligatures, and also additional cleaning elements arranged diametrically opposite. The additional cleaning elements are made as four short flat plates, which are fixed as consoles on the driving horizontal shaft, and their planes are arranged in the plane passing through transversal cross-section of the shaft. The middle plates have lesser rigidity than side ones. The middle parts of all the plates are connected between each other by an axle which passes therethrough with spacings. On the axis between the plates flat compression springs are mounted. |
