This invention concerns a feeding wheel for the use in wood processors and wood harvesters for the feeding of wood trunks (6) past debranching knives (7). The feeder wheel comprises an inner steel cylinder (2) provided with an outer thick layer or mantle (3) of polyurethan rubber that is vulcanized to the steel cylinder (2). Radial holes (4) are arranged extending through the supporting steel cylinder and the elastic layer. The holes have the same diameter all through and allow juice, bark parts and other debris to fall through the wheel so that it can not serve as a lubricant and thus the grip of the wheel (1) is increased. Alternatively the holes can be used for the fastening of grip increasing metal means floating in the holes so that they can be pushed into the elastic material, and thereby not impairing the quality of the tree. |
