    • Elongated compound plates are severed at desired intervals in a bandsawing machine wherein the frame for a travelling saw band is movable in and counter to the direction of movement of the plates as well as in and counter to a second direction at right angles to the first direction. The frame further supports a tool which is located behind the band, as considered in the second direction, and is provided with two deburring surfaces serving to penetrate into the kerf which is formed while the frame moves simultaneously in the first and second directions. The freshly severed portions of plates are accelerated in the first direction to increase the width of kerfs so that the band can be readily retracted counter to the second direction prior to returning to a starting position by moving with the frame counter to the first direction. The widening of the kerf can be effected by the tool or by a conveyor which receives successively separated portions of moving plates and accelerates them in the first direction. The plates are free to catch up with and to push the freshly separated portions in the first direction as soon as the band is retracted counter to the second direction.
    • 在带锯机中以期望的间隔切割细长的复合板,其中用于行进的锯条的框架可在板的运动方向上移动并相对于板的运动方向移动,并且与第一方向成直角的第二方向 。 框架还支撑位于带后面的工具,如在第二方向上所考虑的那样,并且设置有两个去毛刺表面,用于穿过当框架沿第一和第二方向同时移动时形成的切口。 板的新鲜切割部分沿第一方向被加速以增加切口的宽度,使得带可以在通过与第一方向相反的框架移动而返回到起始位置之前容易地相对于第二方向缩回。 切口的加宽可以通过工具或输送机来实现,该输送机接收连续分离的移动板的部分并且在第一方向上加速它们。 一旦带子退回到第二方向,板就可以自由地赶上并按第一方向推动新鲜分离的部分。
