Factors that influence the lamination performance of Pinus spp.

Abstract

This research was developed with the objective of evaluate the influence of some factors on the yield in the lamination of Pinus spp. The data were collected in 33 veneer and plywood factories in the State of Paraná. In the log lamination with bark, the average was around 48%. After the rounding of logs, the average increased to 73%. The analysis of the linear regressions indicated positive correlation with the log diameter x veneer volume and log volume x veneer volume and negative correlations for conicity x veneer volume and log diameter x conicity.
