Automatic feed assembly for circular saws - has fixed and movable saw blades controlled by feelers
Реферат: Timber may be trimmed into planks, using two circular saws, one fixed, one movable. Correct width is adjusted before a plank advances under the blades. The gauge has a pair of fixed feeler heads aligned on one saw blade and a pair of movable feeler heads controlling the position of the other saw. The plank travels sideways, touching the fixed heads, and the movable heads are brought in to touch the opposite sides. A signal is generated and the movable heads retract until one loses contact. A second signal is given and the plank moves under the correctly positioned saw.
