EFFECTS OF SAWING PATTERN ON DRYING RATE AND RESIDUAL DRYING STRESSES OF PINUS RADIATA LUMBER

Flatsawn and quartersawn Pinus radiata (radiata pine) sapwood boards were dried in a tunnel dryer in three runs using three drying schedules. These schedules represented low temperature (LT), accelerated conventional temperature (ACT) and high temperature (HT) drying. In each run, the boards were as...
