Abstract: The present invention relates to an operating system for moving a feed apparatus of elongated pieces of timber, particularly logs, into a transversal feed apparatus, for moving reciprocatingly the feed apparatus, the feed apparatus being arranged to feed pieces of timber piece by piece from a reception point (7) to a discharge point (8) and the feed apparatus having a step-like configuration and the feed apparatus comprising a reception step member (1), which is movable reciprocatingly between the initial position thereof, in which the upper surface part (9) of the reception step member is substantially on the level of the reception point (7), and the discharge position, and a discharge step member (4), which is movable back and forth between the discharge position thereof, in which the upper surface part (15) of the discharge step member is substantially on the level of said discharge point, and the reception position thereof, and possibly one of more additional step members (2, 3).

Abstract: The invention relates to a method and device for turning a log. In the method, the turning is carried out in two stages in such a way that the first stage comprises the turning of the log to a somewhat oblique position in relation to the transverse direction of two rollers (2) rotating in opposite directions, and the second stage comprises the turning of the log by means of the rollers in a controlled manner onto a conveyor (11), which is at the bottom of a trough (14). The device according to the invention has two rollers (2) rotating in opposite directions and, adjacent to each roller, a preferably V-shaped blade (3), which effects the first stage of the turning. The second stage of turning, effected by the rollers (2), is controlled, a factor which provides a considerable improvement in efficiency.
