PURPOSE:To aim at transforming the angle of a square lumber and the like with close tolerances so as to make it shiftable to another course of work, by securing the lumber received in the work receiving mouth of an arm being supported swingably, while setting this fixation free upon gyration of the arm. CONSTITUTION:A square lumber (a) fed from an inclined feeding passage is taken in a receiving mouth 6 of an arm plate 1, which swings aroung a shaft 8, and locked by pressing force of a buffer plate 14 via an adjustable buffer plate 17 operated by a second cylinder 15. A bed frame 21 is provided with a cylinder 12 swingable a around a shaft 12 while the nose of its piston rod 13 is pivotedly attached to the backside of the arm plate 1 of an arm 7. When the first cylinder 12 is operated, a butt plate 11 secured to the arm plate 1 continues to swing till it hits a buffer pin 30, altering the attitude of the square lumber (a) whereby the square lumber (a) is delivered in the longitudinal direction upon release of the fixation by the adjustable buffer plate 17. |
