摘要： An improved dobby uses linkages for controlling the oscillations of the fixed and mobile knives about their axes which comprise first levers fixed to the knives, second levers fixed to control shafts, and connecting rods which link said first and second levers together to form an articulated parallelogram.
In this dobby, the hook operating rods are controlled by the same shafts which control the knife oscillations, by means of an articulated joint.

摘要： A dobby (10) including a vertical lever (18) connected with a heald frame (12) and having hook levers (28a, 28b) respectively and pivotally secured to both ends thereof, knife hooks (32a, 32b) respectively and pivotally attached to both ends of a swing lever (34a, 34b), which is swung in such a way that both ends thereof move alternately toward and away from the vertical lever (18), and engageable with their corresponding hook levers (28a, 28b), and a command device adapted to control the engagement between the hook levers (28a, 28b) and their corresponding knife hooks (32a, 32b) so as to move the heald frame (12) up and down for production of fabric of a desired pattern. The knife hooks (32a, 32b) are eccentrically and pivotally secured on their corresponding end portions of the swing lever (34a, 34b) in order to ensure smooth engagements between the hook levers (28a, 28b) and their corresponding knife hooks (32a, 32b) without developing any excessive swinging of the swing lever (34a, 34b). Each of the knife hooks (32a, 32b) is actuated in such a manner that, when its corresponding end portion of the swing lever (34a, 34b) assumes its most-advanced position relative to the vertical lever (18), the knife hook (32a, 32b) provided at its corresponding end portion of the swing lever (34a, 34b) assumes an eccentric position biased toward its corresponding hook lever (28a, 28b).
