ABSTRACT:
A method and apparatus for around the curve sawing is shown and described wherein a group of roller assemblies are positionable along a selected semicircular path having a point of tangency relative to lines of cut provided by an assembly of cutting blades whereby each roller assembly provides a transport path normal to the axes of rotation for each roller assembly and tangent to the selected semicircular path. Upon actuation of the roller assemblies, as positioned along the selected semicircular path, the wood product, as captured between rollers of the roller assemblies, moves along the selected semicircular path and into the cutting device for cutting along concentric lines of cut. The method and apparatus is particularly well suited for use with tree species having irregularly shaped protrusions and formations deviating from an idealized curved centerline of the log or cant.
