Abstract
Abstract An apparatus for laminating wood particles arriving from a separator sorting the particles as to size comprises a plurality of plates inclined downwardly toward the transport path and formed with mutually parallel downwardly convergent channels which, with vibration of the plates, orient the particles as they are deposited by the plates in successive layers.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
129 words
In an apparatus for orienting particles and depositing same upon a receiving surface in respective layers, wherein a particle separating device produces streams of different-size particles, the improvement which comprises: a plurality of orienting plates each inclined at an angle to said surface and spaced apart to deposit said particles in respective layers upon said surface without free fall, each of said plates being formed with a base extending downwardly toward said surface, and a plurality of upwardly open and downwardly converging chutes mounted on said base but terminating short of the lower end thereof; means for vibrating said plates; and deflecting means for directing selected streams from said device onto selected ones of said plates whereby said plates deposit the respective layers with particles of different particle sizes.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
29 words
The improvement defined in claim 1 wherein said device is constructed and arranged to dispense a stream of fine particles without interception by such plates onto said receiving surface.
