Abstract
In a height-adjustable workpiece feeding device for a wood planing machine, two rollers are journalled on two cam follower units which are respectively slidable along two guideways in a support carriage between upper and lower positions. A connecting rod unit has two cam units secured thereon, and is rotatable transverse to the rollers so as to synchronously rotate the cam units between first and second positions, where first and second regions of cam surfaces of the cam units abut against the cam follower units, respectively, thereby placing the cam follower units, as well as the rollers, in the upper and lower positions.
