<p>A means for rotating tree trunks or equivalent into correct position regarding their curvature, prior to their feeding into a machine processing round timber. The means is primarily intended to be used as an ancillary in a timber feeding means which feeds the tree trunks into a processing machine, because branch stubs which have remained on the tree trunk may impede the turning of the tree in the feeding means. The means of the invention has been carried out in such manner that the means comprises one or several rotator pairs, each such pair being composed of two rotators provided with a helix and disposed in the tree trunk feeding means, and which in their operating position are elastically urged against the tree trunk and which are arranged to rotate with reference to each other so that the tree trunk therebetween rotates, forced by the helices, in the desired direction.</p> |
