Abstract
L'alignement précis des équipements de coupe est un moyen recommandé pour assurer la maximisation du rendement matière et de la qualité des produits manufacturés. Les tendances de l'industrie s'orientent de plus en plus vers l'utilisation de scies minces et vers une réduction maximale des dimensions-cibles. Il est essentiel pour la qualité des produits désirés que les préposés de l'entretien et de l'alignement des machines fassent un ajustement de haute précision. Le succès d'un alignement précis dépend en grande partie de la précision des outils utilisés pour accomplir ce travail. Un niveau de précision est calibré de façon telle à permettre de mesurer les déviations du nivelage par unité de millième de pouce. Ce livre propose des formules pratiques que l'expérience en milieu de travail peut mettre à profit. Les méthodes d'alignement s'appliquent à l'ensemble de la machinerie des centres de transformation: équarrisseuse-déchiqueteuse ("Chipper Canter"), scie de tête à ruban avec le chariot, scie de tête à rubans jumelés ("Twin Band"), refendeuse verticale, refendeuse à ruban horizontal, scie de tête circulaire avec le chariot et déligneuse à scies multiples ("Bull Edger").

Abstract
The purpose of this study is to investigate and record the principal problems associated with chipped surface quality at canter lines and evaluate degrade and value losses due to these problems. Mill measurements were conducted in five member sawmills in British Columbia to evaluate the value losses and lumber degrades due to chipped surface defects. The test lumber was sampled from the planing mills to identify the chipping losses and main problems. The five types of chipped surface defects influencing lumber grade are: knot tear-out; failure to remove chipped spline channel; torn grain without knots; scalloping; and chipped thin end. Average value losses for all mills were $11.4/MBF and $12.6/MBF in freezing and non-freezing conditions respectively. Removing the non-freezing data from one mill changed this to $11.4/MBF and $9.0/MBF respectively. Knot tear out caused 60% of lumber to be degraded. On average, over 55% of knots had tear-out. 42.3% of trim length was caused by failure to remove chipped spline channel.

Abstract
This paper investigates the feasibility of increasing bandmill production by proportionally increasing both blade speed and lumber feed speed. A modal analysis of the bandmill and bandsaw was conducted and resonant conditions, likely to impair performance, were identified. Cutting tests were conducted to determine the effect of increased blade speed on cutting accuracy, surface finish and sawdust quality. The tests were conducted at blade speeds of 10,000 fpm, 12,500 fpm and 15,000 fpm and examined the effect of tipped and swaged blades cutting Coastal Hem/Fir and Interior SPF.

Abstract
The global objective of the project is to investigate the feasibility of increasing bandmill production by proportionately increasing both the blade speed and the lumber feed speed. The objective of this phase of the project is to transfer the results of the laboratory experiments to the sawmill industry. The work described in this report covers the transfer of the technology to two sawmills. The first report has a more detailed introduction to the project and a review of the literature.

Abstract
Le rapport présente les résultats à la productivité et à la qualité de produits pour six usines satellites étudiés dans l'est du Canada. Un modèle de coûts est aussi contenu dans le rapport. Le coût au mètre cube d'un système de récolte par arbres entiers comprenant une usine satellite capable de produire des copeaux et des billes de sciage est comparé à celui d'un système comprenant une ébrancheuse-écorceuse-déchiqueteuse et une façonneuse à la souche et produisant les copeaux et les billes de sciage en forêt. Le modèle inclut les coûts de production pour la récolte, le transport routier et l'usine satellite.
