Abstract: In a method for operating a sawline for logs, the sawline including a conveyor for conveying a log in the sawline, and a processing apparatus for processing the log, the log is fed into the sawline, the log is conveyed onwards in the longitudinal direction in the sawline, the overall length of the log is determined, and the log is guided into the processing apparatus, with which the log is processed at the same time, when the log is conveyed onwards in the sawline. The length of the part of the log that is outside the processing apparatus is determined with a camera apparatus, and the location of the end of the log in the processing apparatus is determined on the basis of the overall length of the log and on the basis of the length of the part of the log that is outside the processing apparatus.

Abstract: A log handling device, having a rotatable rotor provided with a log handler, and a feeder attached to the rotor for conducting an operating medium to the log handler. The feeder is arranged to wind around the rotor when the rotor is rotated in a first direction, and which feeder is arranged to unwind from around the rotor when the rotor is rotated in a second direction. The log handling device includes a rotatable second rotor to which the feeder is attached, and an operating device for rotating the second rotor synchronously with the rotor, such that the feeder is arranged to wind around the second rotor when the rotor is rotated in the second direction, and such that the feeder is arranged to unwind from around the second rotor when the rotor is rotated in the first direction.

Abstract: An apparatus for processing logs includes a conveyor for conveying a log in the apparatus, a chipping canter, which comprises two chipping head assemblies for chipping the opposite sides of a log, and a saw, which comprises at least two circular blades for sawing the log on at least one side. The chipping head assemblies are installed on different shafts than the circular blades. The circular blades of a saw are situated before the chipping canter in the conveying direction of a log and are arranged to, before chipping, partly or completely saw off from the log the parts of the log that are to be chipped with the chipping head assemblies.

Abstract: Guide arrangement for the handling elements (1), more particularly for the rotators/aligners, of a wood object, such as a log (4), for guiding the control elements (2), such as hydraulic leads, electrical leads and/or pneumatic leads, fitted to the handling elements, wherein the control elements are fixed to the rotatable frame piece (3) of the handling element, into which frame piece the logs (4) can be fed, and in that the guide arrangement comprises at least one guide element (5) guiding the control elements, which is fitted to pass via at least one guide part (6) as well as to the rotatable frame piece of the handling element, and in that the control elements are fitted to the guide element to control and/or to compensate the movement of the control elements.

Abstract: A circular saw for sawing wood pieces, which circular saw has blade guides (5, 21) which are fastened to fastening arms (4, 22), and in which the fastening arm (4, 22) of the blade guides (5, 21) is fastened concentrically with a drive axle (6, 23) of the saw blade (1) pivotedly so that the fastening arm is able to turn around the drive axle (6, 23), and the blade guides are fastened to the fastening arm (4, 22) pivotedly with a fastening bearing (10, 24) so that they are able to turn around the fastening bearing (10, 24).
