Definitions

  • Figure 13a shows how the same machine by the application of parallel cuts can be used to make wedge based products such as the interlocking "drop segments" a product as earlier described by the current inventor in other invention specifications.
  • Figure 20 shows how twin saws cutting concurrently or alternatively could speed cutting times in a twin saw reciprocating system.
  • Figure 32 shows a T chord could be machined on an apparatus that accords with the invention.
  • Figure 1 shows sector based sawing patterns disclosed in the present inventor's United States Patent 6032708 titled Radial sawing log holder and method.
  • the present invention has for its objective the efficient production on the one machine of target rectangular sections or the production of slabs that can be easily processed to target rectangular sections on other devices as well as the production of sectors that could be processed as pictured in Figure 1 or in ways later described in this specification.
  • Figure 3a represents a typical backsawing pattern for logs with growth and drying stresses.
  • a 400mm diameter log is shown with 107mm by 28mm boards and 162 by 28mm boards which are typical target green sawn sizes suited to drying and value adding.

  • a growth stressed log if boards are cut in this region with faces parallel to the other boards, they are subject to spring and bow and uneven drying distortion and are low quality sections of timber.
  • Wider backsawn boards will generally not be cut due to excesses in cupping and shrinkage during drying and use in such products as flooring.
  • Backsawn boards generally shrink around twice as much across their broad face as quartersawn boards do during drying. Backsawn boards are less stable in use.

Abstract

L'invention concerne un procédé et un appareil pour la production d'un rondin scié sur quartier et re-scié rectangulaire cible. D'autres sections de rondin basées sur des secteurs pourraient ou peuvent être produites. L'utilisation du procédé permet l'introduction de systèmes associés. Des motifs de sciage et d'usinage appliqués sont définis par rapport à des plans radiaux choisis ou désignés émanant du centre longitudinal du rondin, les lignes de sciage primaires étant décalées par rapport aux plans radiaux et parallèles à ceux-ci. Les découpes parallèles décalées sont effectuées à partir de l'extérieur du rondin à une profondeur choisie ou désignée ou calculée dans le rondin. Un exemple de mode de réalisation de l'invention pour le traitement d'un rondin met en œuvre la réalisation de découpes parallèles décalées de chaque côté de six plans radiaux espacés de manière uniforme de 60 degrés les uns des autres. D'autres découpes peuvent être réalisées à angle droit par rapport aux découpes parallèles décalées, et sur des plans radiaux. Des découpes radiales, si elles sont effectuées, et certaines autres découpes, sont habituellement effectuées après que certaines sections ont été séparées du rondin et retirées de celui-ci. Le procédé est applicable à un petit rondin et à un grand rondin, et assure l'exclusion efficace du bois de cœur à partir de produits cibles et la production de grands volumes de rondins aussi près que possible de véritables sciage sur quartier et de re-sciage. Le procédé permet l'application pratique d'un sciage à effilement dans de petits rondins, maximisant la résistance et la stabilité du produit scié. Le procédé peut commander ou minimiser l'impact néfaste de contraintes de croissance de rondin au cours de la production et de l'utilisation.
