Abstract: A saw assembly for reducing logs while passing the logs at least once through the assembly and resawing the resultant sawn blocks while re-passing the blocks at least once through the saw assembly. The assembly comprises a pair of chippers (1) and at least one pair of band saws (2) located downstream thereof, and a pair of guide-and-feed devices (9) located between the chippers and the band saws. The components in each of these pairs of assembly units are located opposite one another on different sides of the center line of the saw line and are adjustable in relation to the center line. In order to simplify the construction and handling of the saw assembly, the saw assembly includes means (21) which, when reducing passing logs, cause the guide-and-feed devices (9) to synchronously accompany the setting movements of the chippers (1) in relation to the center of the saw line, and means (23) which, prior to a resawing operation, displace the guide-and-feed devices (9) in relation to the chippers (1) in a direction towards the center of the saw line, for engagement with the sawn block which is to be resawn into planks, this block passing free of the chippers.

Abstract: A band saw, especially intended for sawing logs with the grain or dividing wood blocks, comprising upper and lower band pulleys (6,4) which can be adjusted relative to one another. Extending around the pulleys is an endless, band-like saw blade (11) which is driven by one (4) of the bandpulleys. The lower band pulley (4) is journalled in a frame structure (3) which can be moved along two mutually parallel guides (13,14) extending at right angles to the feed direction of the material to be sawn. The frame structure carries a post (5) which in turn carries at the top thereof the other band pulley (6). In accordance with the invention the one guide (14) is located substantially vertically above the other guide (13), suitably so that the two guides (13,14) are located in a common vertical plane which passes vertically through the post (5).
