Abstract

La lame (8) de cette scie, mobile autour de son axe longitudinal, peut être orientée durant la coupe par la poignée (22) ou par une molette (37). Si la conduite se fait par molette (37), la poignée conduit alors le cadre. Si la poignée (22) conduit la lame, le cadre est li­ bre de son orientation.
Afin d'éviter une torsion de la lame (8), les tenons (6, 28) de celle-ci doivent être synchronisés par un organe qui longe le cadre et qui consiste soit en un dispositif à courroie, soit à tiges et engrenages, soit encore à câbles teleflex (36).
Pour rendre le jeu des organes inopérants vis-à-vis de la tor­ sion, les mouvements de l'organe de commande sont transmis tout d'abord au centre du dispositif de synchronisation des tenons qui les retransmet symétriquement à ceux-ci. The blade (8) of this saw, movable around its longitudinal axis, can be oriented during cutting by the handle (22) or by a wheel (37). If the drive is done by thumb wheel (37), the handle then drives the frame. If the handle (22) guides the blade, the frame is free from its orientation.
In order to avoid twisting of the blade (8), the pins (6, 28) of the latter must be synchronized by a member which runs along the frame and which consists either of a belt device, or of rods and gears, or again with teleflex cables (36).
To make the play of the members inoperative vis-à-vis the torsion, the movements of the control member are first transmitted to the center of the stud synchronization device which retransmits them symmetrically to them.
