Abstract
A chip thickness classifier comprising a drum mounted for rotation about its longitudinal axis and having its periphery formed by a plurality of discrete longitudinally extending bars of elongated cross-section. The bars are arranged in substantially shingled relationship with one side of each bar spaced closer to the axis of rotation of the drum than the other side of the bar thereby to form outlet passages between adjacent bars. The outlet passages are substantially axially extending slots having their major width dimension measured substantially radially of the axis of rotation of the drum. Each of said bars is mounted for rotation about a longitudinally extending axis of the bar and the bars are interconnected by an adjustment mechanism that applies simultaneous incremental movement to stepwise rotate said bars and change said width dimension of the outlet passage. The drum is rotated in the direction wherein the side of each said bar closest the axis of rotation of the drum leads.
