<p>A tooth retainer is screwed by means of a shell-shaped foot onto the roller body surface, with the tooth shaft fitting in a hollow holder running out from the tooth, the tooth being held in the retainer by a securing device parallel to the roller axle, as cutting tool on a cutter roller. The holder profile is made up from a row of overlapping circles, pref. three. The securing device is an elastic rod unit, mounted in the walling of the shaft holder lying in the operative direction of the tooth (10) and partially penetrating into the hollow profile. The tooth shaft has a fitting groove (32). The profile may run through the foot.</p> |
