The applied root head cleaner comprises a driving horizontal shaft with two main flat elastic cleaning elements, tangentially fixed thereon, the free ends of which are connected with the shaft of the cleaner with the aid of flexible ligatures, and also additional cleaning elements as elastic bands which are arranged diametrically opposite. The additional cleaning elements in the longitudinal-vertical cross-section are of the form of semicylinders with convex parts, arranged on the outer side, which are made as transversal grates, through the middle part of which thin resilient cylindrical rods pass. Between the rods and nonworking parts of the elements of the grates regulated stops are fixed. |
