  • Spacer design for dobby rocker members
    Patent number: 5209268
    Abstract: In a weaving mechanism which includes rocking members for controlling the movement of heddle frames for forming the shed in weaving machines, the rocking members are separated from one another on a common support shaft by spacers interposed therebetween which spacer members are provided with projecting bosses which come into contact with bosses of adjacent spacer members. A rod cooperates with an arm of the spacers to insure the spacers are non-pivotably retained while the rocking members are moveable between the bosses extending therefrom.

  • Synchronized rotating dobby for weaving looms
    Patent number: 4544000
    Abstract: For the purpose of producing a synchronized rotating dobby capable of operating equally well in both directions of rotation, a plate fixed to a heddle-frame displacing eccentric is provided with a second notch diametrically opposite the immobilizing first notch in which engages the nose element of a pivoting lever actuated by the reading device. This second notch cooperates with the oppositely located lever to ensure maintenance of the correct positioning of the plate.
