  • Publication number: 20210291254
    Abstract: A processing device processes a frame-shaped workpiece which extends in a prescribed extension direction, and includes, integrally, a plate-shaped web surface portion, a plate-shaped first flange portion that bends and extends from one end of the web surface portion, and a plate-shaped second flange portion which bends from the other end of the web surface portion and extends in the opposite direction to the first flange portion. The processing device includes a shaping device which conveys the workpiece in the extension direction, and an exit side pinch roll device provided further downstream, in the workpiece conveying flow direction, than the shaping device. The exit side pinch roll device includes a first roll which presses a central region of an upper surface side of the web surface portion, and a second roll which presses a central region of a lower surface side of the web surface portion.

  • Publication number: 20160258649
    Abstract: An indoor unit includes at least one air outlet including an inner air-passage wall and an outer air-passage wall located outwardly of the inner air-passage wall, and at least one outlet vane disposed in the air outlet. The outlet vane is rotated about a rotation axis and deflects air blown from the air outlet at an angle of rotation. While the indoor unit is in an operating state, the outer air-passage wall and the outlet vane define therebetween an outer air passage through which the blown air passes, and the inner air-passage wall and the outlet vane define therebetween an inner air passage through which the blown air passes. The outlet vane is rotatable to an upward position at which the outer air passage between the outer air-passage wall and the outlet vane is narrowed to have a higher air flow resistance than the inner air passage.
