Abstract

Improvements in dobby machines, which improvements comprise a heald actioning device consisting of two horizontal shafts across the width of the dobby machine and carrying individual sets of eccentrics, each of which is connected to the lifter-motion drive. A horizontal tie-rod has one end thereof connected to the lifter-motion drive substantially at the center of gyration thereof and is subjected to a reciprocating displacement due to the eccentric rotation. The opposite end of the tie-rod is articularly connected to the central part of a vertical lever, the one end of which is pivotally connected to a shaft, the other end of the lever driving the corresponding heald formation.
