The present invention relates to a portable sawmill with a frame structure (1) and a saw blade (3) extending essentially vertically upwards in relation to the frame structure, tables (2) cooperating on both sides of the saw line of the saw blade and reciprocating on the frame structure (1) parallel with the saw blade (3), wherein there are friction reducing means on the path of the tables (2) by means of which the tables are movable to and from in the direction of the saw line by the saw blade (3). According to the invention, the friction reducing means used are fixed sliding surfaces (5), such as slide rails or sliding bodies arranged sequentially on the table path.

La scierie portable de présente invention est constituée, d'une part d'une structure de bâti (1), d'autre part d'une lame de scie (3) montée sensiblement verticalement par rapport à la structure du bâti, et enfin de plateaux-navettes (2) coopérant de part et d'autre du plan de la lame de scie. Ces plateaux-navettes exécutent des mouvements de va-et-vient sur la structure de bâti (1), parallèlement au plan de la lame de scie (3). Des réducteurs de frottement équipent le chemin de va-et-vient des plateaux-navettes (2) dans le sens du plan de la lame de scie, au niveau de cette lame (3). Selon l'invention, les réducteurs de frottement sont des surfaces de patin fixes (5), et notamment des rails-glissières ou des corps de patin disposés en série sur le chemin de va-et-vient des plateaux-navettes.
