Abstract

An infeed table for an edging device adapted to trim the longitudinal wane edges of a sawn cant to produce dimensioned lumber as the cant is moved therethrough along a prescribed edging path including an infeed conveyor for moving the sawn cant into the edging device along the edging path; and a pair of positioning assemblies are positioned along the infeed conveyor means at spaced apart positions to selectively clamp the cant therein and shift the cant transversely of the edging path to orient the cant with respect to the edging path. A manual control is provided for the positioning assemblies to selectively shift the cant and an automatic control is also provided for shifting the positioning assemblies to a position centered on the edging path when the manual control is not activated. A set control is provided for causing the positioning assemblies to shift one edge of the cant to fixed distance from the edging path.
