13 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 centre line of the saw line and are adjustable in rela- tion to the centre line. In order to simplify the construc- tion 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 centre 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 centre of the saw line, for engage- ment with the sawn block which is to be resawn into planks, this block passing free of the chippers.
