    • A labeling apparatus 20 is for applying labels 29 to articles F advanced along an article conveyor 21. The labeling apparatus may include a frame 22 to be positioned adjacent the article conveyor, and a labeler 23a, 23b carried by the frame. The labeler may include a housing 31, a rotary bellows wheel 24 carried by the housing, and bellows 26a-26h carried by the rotary bellows wheel. The rotary bellows wheel and adjacent portions of the housing may define a porting arrangement 42a-42h, 43a-43h, 44, 45, 55a-55h with axially adjacent fixed and moving parts for selectively connecting the rotary bellows wheel to a fluid flow to selectively control internal fluid pressure for the bellows so that each bellows is movable between a retracted label pick-up position and an extended label-applying position and so that a peak negative internal fluid pressure is applied at the label pick-up position and a peak positive internal fluid pressure is applied at the label-applying position.
    • 标签装置20用于将标签29施加到沿着物品传送器21前进的物品F.标签装置可以包括邻近物品输送机定位的框架22​​和由框架承载的标签器23a,23b。 标签机可以包括壳体31,由壳体承载的旋转波纹轮24和由旋转波纹轮承载的波纹管26a-26h。 旋转波纹轮和壳体的相邻部分可以限定具有轴向相邻的固定和移动部件的移位装置42a-42h,43a-43h,44,45,55a-55h,用于选择性地将旋转波纹管轮连接到选择性地流体流 控制波纹管的内部流体压力,使得每个波纹管可在缩回的标签拾取位置和延伸的标签施加位置之间移动,并且在标签拾取位置处施加峰值负的内部流体压力,并且峰值正 在标签施加位置施加内部流体压力。
