<p>A positive dobby machine which has return knives (16a), (16b) formed so as to move in parallel and vertical pressure bearing planar surfaces (18a), (18b) in their direction of movement. First pressure bearing planar surfaces (7a), (7b) formed so as to be able to come into planar contact with the surfaces (18a), (18b) of the knives (16a), (16b), respectively, are formed on hooks (6a), (6b) pivotably secured to the upper and lower ends of a vertical lever (5). The vertical lever (5) is driven by urging the surfaces (7a), (7b) of the hooks (6a), (6b) in a planar contacting state with the pressure bearing surfaces (18a), (18b) of the return knives (16a), (16b), respectively.</p> |
