摘要： A flat reducing and sawing installation for processing tapering logs includes a reducing section and a sawing section through which logs pass in sequence. The reducing section includes two reducing disks which can each be moved outwards by respective positioning devices. The sawing section includes at least two laterally movable saw blades. The position of the reducing disks is controlled by an electronic evaluation and control unit on the basis of profile data fed in about the log, which indicates that at least one of the disks is about to grind sufficient material from one side of the log to form a plank of a minimum acceptable thickness, length and width. Under these circumstances, the control unit moves the appropriate reducing disk outwardly by at least the minimum acceptable thickness to allow the outermost saw of the sawing section to saw off the resulting plank.

摘要： A band sawing machine has an endless saw blade entrained over two saw pulleys and two blade guides. Lateral displacements of the saw blade from a preset position occurring during a sawing operation are measured by a position sensor. The position sensor controls an actuator which applies a corrective twist or lateral movement to at least one of the blade guides to return the blade to the present position.

摘要： A band sawing machine has an endless saw blade entrained over two saw pulleys and two blade guides. Lateral displacements of the saw blade to an equilibrium position, as occur during a sawing operation, are countered by a corrective tilt of a planar front face on one or both of the blade guides. The saw blade, by means of tensioning, is constantly pressed against the front face, or faces of the blade guides.

摘要： A crude curved log with an essentially circular cross-section is before a first machining cycle in a working machine fixed in a rotary condition where the longitudinal sectional plane comprising the maximum curvature is horizontal, and is then measured and processed along curved paths determined in a computer unit on the basis of the measured curvature. Thereafter the central block, thus obtained is processed, in a second cycle along paths having the same curvature as the first cycle by utilizing the same command signals as in the first cycle are used, possibly with a correction for changed lateral position of the block.

摘要： In a band sawing machine having an endless saw blade entrained over two saw pulleys and two hand guides, lateral displacements of the saw blade equilibrium position which occur during a sawing operation are countered by a corrective lateral movement of the saw blade relative to a feed path of the goods to be sawn, by laterally adjusting the position of at least one of the blades guides.
