The invention provides an apparatus for feeding trees in their longitudinal direction into a processor along the treatment line. The apparatus may be used for lopping, measuring, spray-protecting, cutting, sorting, or any other corresponding operation. The apparatus comprises two feeding rolls or rollers provided with surfaces of sufficient adhesive capacity. The feeding rolls are arranged above and underneath the feeding line of the trees and are mounted on substantially horizontal axles each of them at an arm of its own. The arms are pivotable in the vertical direction and are fastened, by means of articulated joints, at a vertical distance from each other, to the frame of the treatment line. A cylinder-piston apparatus is arranged between the arms of the feeding rolls and produces the compression force required by the feeding rolls and guarantees continuous drive by both feeding rolls. The upper feeding roller is placed somewhat closer to the beginning of the treatment line than the lower feeding roller. |
