Abstract Method and means for preparing adhesive coatings. A bank of extrusion devices forms extrusions of adhesive that fall to form smooth-flowing filament streams of adhesive that make flowing contact with the face of the object being coated. A striped pattern of adhesive is produced which is converted into a substantially continuous glue line with the application of heat and pressure. A veneer-handling conveyor line for producing plywood panels, where veneer pieces travel on a conveyor and thence are directed either through an adhesive-application station or a course which bypasses such station. The veneer pieces are reassembled downstream from such station to form a traveling series of veneer pieces comprising veneer pieces with adhesive coatings interspersed with veneer pieces free of adhesive. The veneer pieces are then stacked in the order that they appear in said traveling series to complete the layup of plywood panels.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
35 words
The apparatus of claim 1, wherein said bank of devices includes multiple rows of devices extending transversely of said path, the devices of one row being staggered with respect to the devices of another row.
Claim 2
Dependent Claim
57 words
The apparatus of claim 1, wherein each extrusion device comprises a body removably mounted on the base of said tank, said nipple forming the bottom end of said body and the body including a threaded stem joining with said nipple forming the top end of the body, said passage means extending through the stem and said nipple.
Claim 3
Dependent Claim
21 words
The apparatus of claim 3, wherein said stem has a top face bounding the top thereof which has a convex taper.
Claim 4
Dependent Claim
26 words
The apparatus of claim 4, wherein an extrusion device is mounted on the base of the tank with its said top face projecting above said base.
Claim 5
Dependent Claim
60 words
The apparatus of claim 1 which further comprises another veneer conveyor defining another path of travel for veneer pieces, said other path extending generally in the same direction but being vertically spaced from said first-mentioned path and constituting a bypass of said first-mentioned path, and means for directing veneer pieces selectively either to said first-mentioned or to said other conveyor.
Claim 6
Dependent Claim
29 words
The apparatus of claim 6, wherein a conveyor feeds the means for directing veneer pieces, and said other conveyor deposits pieces on said first-mentioned conveyor at Its discharge end.
