  • Publication number: 20140331619
    Abstract: A packaging machine includes a shaping device including a conveyor drive mechanism and a bottom tapping mechanism and shaping a packaging bag filled with article so that the bag has a predetermined thickness. The conveyor drive mechanism includes a pair of side conveyors movable forward and backward. The conveyors are capable of pressing the bag filled with the article when moved forward. The conveyors are configured to be run in parallel to the moving direction of the bag substantially in synchronization with movement of the bag. The tapping mechanism includes a receiving plate disposed over the filling step and one or more steps following the filling step. The receiving plate is moved up and down so that the bag bottom is tapped, when the bag filled with the article is stopped between the filling step and one or more steps following the filling step.

  • Publication number: 20130259694
    Abstract: In manufacturing a multi-finger pinned root pin-coupling a turbine blade made of a high-strength material and a rotor disc, a reamer used to ream a pin insertion hole formed through a turbine blade attachment base is removed from the pin insertion hole while being rotated so as to cause a scratch formed by a chip on the inner surface of the pin insertion hole to be inclined with respect to the axial direction of the pin insertion hole. This brings the direction of the scratch on the inner surface of the pin insertion hole and the direction of tensile stress generated on the inner surface of the pin insertion hole adequately close to be parallel to each other. As a result, the fatigue strength reduction caused by the scratch can be inhibited.
