摘要： The invention relates to an apparatus (1) for cutting and splitting a tree trunk (P1) such as a log, said apparatus comprising a cutting saw provided with a frame (30) performing a reciprocating motion relative to the tree trunk (P), a stationary splitting blade (5), as well as a conveyor (7) for bringing the tree trunk in a lengthwise direction to a position below the cutting saw, and a pusher (72b) functionally linked with the conveyor (7) for carrying cut blocks of tree trunk (P1) onwards to the splitting blade (5), such that each cut block of tree trunk (P1) is pushed by means of the pusher (72b) towards the splitting blade (5) for splitting the blocks of wood in a lengthwise direction. The cutting saw is a bandsaw (3), which is surrounded by an enclosure (2) and which bandsaw has its frame (30) mounted in a vertically movable manner above the conveyor (7), such that the bandsaw has at least a cutting part (35a) of its blade (35) pointing in a direction transverse relative to a conveying direction of the tree trunk (P) traveling on the conveyor. When the frame of the bandsaw (3) is on its way from its top position (C) towards its bottom position (D), the conveyor (7) or a section of the conveyor presently below the bandsaw (3) is concurrently set in a standstill condition for cutting the tree trunk (P) with the blade (35) of the bandsaw (3) in a direction transverse relative to its conveying direction.

摘要： A method is used to replace a band saw blade (38) of a band saw (10), wherein the band saw blade (38) is guided over two rollers (34, 36) which can be rotated about horizontal axes (35, 37). The rollers (34, 36) are arranged one above the other in a working position of the band saw (10), and a line (39) connecting the axes of rotation (35, 37) is inclined by an angle (α) with respect to the vertical. The rollers (34, 36) are moved out of the working position and into a band changing position, in which the line (39') runs vertically. The rollers (34', 36') thus moved are then moved toward one another (52). Then the band saw blade (38") hanging down loosely from the upper roller (34") is removed and replaced by another band saw blade.

摘要： A sawing station for sawing a log into planks comprises a log sawing bench (1). The sawing bench is movable in its longitudinal direction parallel with a stationary sawing device (22) and is provided with log fastener devices (5, 7, 9; 6, 8, 10; 35, 36; 39, 40; 50, 51) in connection with the end surfaces of the log. At least one of the fastener devices (9; 35, 36) can be adjusted along the length of the sawing bench so as to adapt to logs (2) of differing lengths. The fastener devices can be adjusted to adjust the position of the log transversely to the longitudinal axis of the table and are displaceable transversely to the longitudinal axis of said table so as to be able to displace the log secured in the fastener devices over one longitudinal side edge of the bench through a distance determined by an operator. A fastener device locking means (7', 8'; 35') locks the fastener devices when saw cuts are made. The sawing bench (1) can be swung about a longitudinally extending axis (A-A) and locked in angular positions in which planks of desired triangular cross-section can be cut from a sawn-off plank that has a substantially semicircular cross-section. The invention also relates to a method of using the sawing bench.
