Abstract (en)

[origin: KR20190120721A] A rotary dobby (1) comprises: a frame (3); lubrication systems (110, 112, 114, 147); a common shaft (12); output levers (14) mounted around the common shaft (12); a drive shaft of the output levers; mechanical driving devices (19) mounted around the drive shaft, wherein each driving device includes mechanical driving devices (19) swinging between coupled and uncoupled configurations to secure or release the output levers, a reading system (30) for selectively switching the driving devices (19) between the coupled and uncoupled configurations, and the drive shaft, the common shaft (12), the driving devices (19) and the reading system (30) are offset in the height direction (Z) with respect to the bottom (5) of the frame. To improve lubrication, the lubrication system includes a lubricant dispenser (120), which includes a plurality of lubricant-emitting outlets that are offset in the height direction (Z) with respect to the reading system (30). The dispenser (120) includes tubular segments (141, 142) fluidly connected via partial obstruction units (148, 150) of a passage section.
