ABSTRACT:
A multiple bandmill (10) for sawing a log (L) moving past that multiple bandmill. This multiple bandmill includes two pairs of bandmills (20, 22 and 24, 26) located at a common longitudinal position with respect to a log being cut. The bandmills comprising the multiple bandmill are slanted with respect to vertical in the longitudinal direction. The bandsaw blades (50, 52 and 54, 56) of each pair of bandmills within the multiple bandmill cross each other in a X-pattern in the log cutting region (30). One bandmill (20, 26) of each pair is located within the area defined by the other bandmill (22, 24). All four sawlines (12, 14, 16, 18) are made at the same time at a single longitudinal location on the log.
