A tensioning member for a blade screen that permits simultaneous tensioning of a plurality of blades in a blade screen, such as for wood chip sorting. The blades may be provided with a sawtooth detail on a bottom edge to reduce the build-up of wood ribbons or fines that would otherwise occur. An elastomeric joint is also provided which allows a dual-frame blade screen to be assembled, while compensating for any phase angle error between eccentric shafts provided to agitate the wood chips by moving the screens.
Elément de tensionnage pour tamis à lames permettant le tensionnage simultané d'une pluralité de lames dans un tamis à lames, tel que pour le triage de copeaux de bois. Les lames peuvent présenter une caractéristique particulière de dents de scie sur un bord intérieur afin de réduire l'accumulation de rubans de bois ou de fines qui pourrait se produire. On a également prévu un joint élastomère permettant d'assembler un tamis à lames à double bâti, tout en compensant les erreurs d'angle de phase entre les axes d'excentrique destinés à agiter les copeaux de bois par un mouvement imprimé aux tamis.
