ABSTRACT:
Strictly translatory substantially lengthwise horizontal motion is imparted to an elongated workpiece such as a cant having top and bottom face surfaces, at least one of which is flat, to feed the workpiece from an orienting station towards a trimming station at which straight, parallel longitudinal side surfaces are formed on the workpiece that are perpendicular to said flat face surface. For such translatory motion, driving dogs engage one face surface at longitudinally spaced portions of a narrow zone thereof which is spaced substantially equal distances from its longitudinal edges; the driving dogs are confined to linear motion in the feed direction; and the other face surface is engaged by horizontal freely revolving rollers extending transversely to the feed direction at intervals therealong. At the orienting station the oriented workpiece is clampwise engaged by the rollers and dogs by effecting relative vertically converging motion between them.
