WAC 296-17A-2904
Classification 2904.
2904-00 Veneer: Commercial production
Applies to establishments engaged in all types of
commercial production of rough veneer. Veneer is a thin layer
of material, usually made of wood or plastic, which is used to
cover the surface of another material. In most instances,
finished veneer will have a superior appearance or quality
than the surface it covers. Rough veneer made of wood
generally involves sawing logs, bolts (lengthwise strips), or
blocks, softening them in vats of hot water or steam rooms to
remove the bark and make the fiber pliable for cutting or
turning. The pieces are further shaped by turning, slicing or
sawing, cutting the single-ply veneer sheets to various sizes
of length and thickness, then drying them in kilns. Rough
veneer manufactured in this classification is generally sold
to manufacturers of veneer products made by laminating rough
veneer to plywood or particleboard. Machinery includes, but
is not limited to, band saws, table saws, stationary knife
machines, rotary lathes, conveyor systems, kilns, forklifts.
This classification excludes sawmill operations which are
to be reported separately in classification 1002; the
manufacture of plywood which is to be reported separately in
classification 2904-01; the manufacture of veneer products
which is to be reported separately in classification 2903; and
the manufacture of other products made from wood or plastic
which are to be reported separately in the classification
applicable to the work being performed. The production of
veneer by employees of employers engaged in the manufacture of
other products is to be included in the classification
covering the manufacture of those products.
2904-01 Plywood: Manufacturing
Applies to establishments engaged in the manufacture of
plywood. Plywood is a structural material made of layers of
wood (veneer) glued tightly together, usually with the grains
of adjoining layers at right angles to each other. (In this
application the word "ply" means one of the sheets of veneer.)
The production of veneer is included in the scope of this
classification when done by employees of employers engaged in
the manufacture of plywood. To form plywood, it may be
necessary to join less-than-full-size sheets of veneer into
full-size sheets. In the joining process, veneer jointers,
taping machines, tapeless splicers, or other methods of
joining veneer, such as stringing and stitching are used. Next, a glue spreader coats the cross banding and core veneers
(front and back) with liquid glue. Once glued, the veneer is
conveyed to a hot press that bonds the veneers into plywood. The panels are removed from the presses, placed in a storage
pile (referred to as a "hot stack") to cool and cure, then
trimmed, sanded, and stacked for conditioning. Plywood may be
impregnated with chemicals to develop wood-plastic
combinations that are harder and denser than ordinary plywood.
After they are inspected and graded according to thickness
and quality, plywood panels are moved by forklift to the
warehouse portion of the plant where they are stacked in tiers
which are separated by a piece of lumber to prevent sagging or
distortion. Pieces are bundled with metal straps, either
manually or with automatic strapping equipment.
This classification excludes sawmill operations which are
to be reported separately in classification 1002;
establishments that manufacture rough veneer as a product
which are to be reported separately in classification 2904-00;
and the manufacture of other products made from wood or
plastic which are to be reported separately in the
classification applicable to the work being performed.
