Abstract

A secondary sawing line for curve sawing comprising a scanner, a chipper canter provided with an infeed guide mechanism, and an edger with guide means for curve sawing.
In order to allow curve sawing, the guiding means are successively removable after adjustment, leaving only short-span guidance under the cutting procedure. According to the invention, the guide means may alternatively function symmetrically to allow sawing along the pith of the log, or fixedly at one side and resiliently at the other side, for performing so-called full taper sawing.
