Abstract
A mechanism for controlling the reciprocating movement of knives associated with rocking hooks connected to the heddle frames of a weaving machine which mechanism includes a pair of rotatable drums oriented parallel to the path of movement of the knives. Each drum includes two profiled grooves in the surface thereof in which tracking members associated with the knives are cooperatively guided.
Claims8
In a knife control mechanism for a heavy closed-shed dobby for a weaving machine which includes two actuation knives which are movable in opposite reciprocating motions along a path in order to selectively engage a rocking double hook carried by pivoting levers coupled to a heddle frame, the improvement comprising, each of said knives having opposite ends, tracking means extending from each of said opposite ends, a pair of drums spaced adjacent said opposite ends of said knives and having central axes generally parallel to the path of motion of said knives, means for rotating said drums in synchronism with one another, each of said drums including a peripheral portion having two spaced profiled grooves therein, and said tracking means being guidingly received within said grooves whereby, when said drums are rotated, said knives will be reciprocately driven along the path of motion.
