A changing raw material supply and smaller, generally lower quality peeler logs,
are causing surface characteristics in veneer that can adversely affect glue-bond
performance. When lower quality logs are peeled, rougher veneer is usually produced.
The typical response by plywood manufacturers is to increase adhesive spread when
using rough veneer....
Current lathe technology, smaller diameter logs, smaller core diameters, and
the sale of higher grade veneer for use in engineered wood products are all factors
contributing to plywood manufacturers using rougher veneer with different lathe
check characteristics. When rough veneer is encountered, plywood manufacturers
typically increase the adhesive spread rate...
This research studied the effects of changing from a traditional manufacturing
system to a cell manufacturing system in a value-added wood products company.
Discrete event simulation was used to describe the current system and the proposed
new systems. Parts were separated into part families that shared similar processing
requirements. From...
Eighteen Ponderosa Pine (Pinus ponderosa Dougl.ex.laws) veneer flitches
were randomly selected and crosscut into paired flitches. Serpentine-end-matched
(SEM) joints were machined in the flitches, joint amplitude equal to the width in
one half of the paired flitch and joint amplitude equal to 2/3 width in the other half
of the...
