摘要:
A device for coupling heddle frames to rod or cable transmission elements of a mechanism for forming the shed in a weaving loom wherein a female mortise member includes a slot having a pair of opposing arms on either side thereof which shot is traversed by the transmission elements which transmission elements pass through a male tenon member which is adjustably fixed thereto with the aid of a locking mechanism and which male tenon member interengages the female mortise member.
摘要:
A rotating dobby for weaving looms wherein the oscillating rods which are connected to the heddles are positively and instantaneously retained in a fixed position upon the disengagement of the coupling hooks by way of which the rods are normally engaged with a rotating drive disk.

The present invention relates to electromagnetic devices for controlling dobbies and other weaving systems, wherein the control unit which contains the electro-magnets is borne by an oscillating frame on which is mounted an equal number of selectors associated with a spring which tends to move them away from the associated poles of magnetic attraction. Each selector acts selectively on the actuating hooks of the dobby, and a fixed stop ensuring its return into applied position against the magnet upon return into a non-actuating position. The device is applicable to the control of a dobby with double swinging levers or to the control of a rotating dobby.
摘要:
A frame for supporting the return levers connected to the heddle frames of a weaving system of a loom wherein the frame is in the form of an upwardly open U-shaped beam connected to a box element mounted to a support structure of the loom.
摘要:
In a jacquard system of a weaving machine in which hooks are actuated by harness cords controlled by knives carried by belts supported on drums drivingly connected to drum disc shafts, independent motors having output shafts are provided for driving the drum disc shafts. The motors are controlled to reciprocate the movement of the belts by first sensors monitoring the rotational movement of the motor output shafts and second sensors monitoring the rotational movement of a primary drive shaft of the weaving machine.
摘要:
A double lift dobby for controlling the movement of the heddle frames of a weaving machine which includes coupling members pivotally connected at each end of double swinging levers which coupling elements are selectively engaged to oscillating plates by reading and transmission elements controlled by extendable members of an actuating mechanism.
摘要:
The hooks associated with the swinging levers in a negative dobby of a weaving machine include a notch and opposing bearing face along their inner edges for positively retaining the hub and one arm of a bolt which is selectively actuated to engage each hook.

The present invention relates to improvements in rotating dobbies. The control of the coupling pawl for connection to the driving shaft is effected by one of two right-angled pivoting levers actuated in the same zone by push elements of the reading device of the dobby. When a lever engages in a notch in a plate fixed to the eccentric, the nose of the engaged one of the pivoting levers pushes a catch on the pawl which pivots the pawl causing the withdrawal of its finger to release connection with drive from the shaft.

A weaving system is provided as a tightly closed beam or casing for containing an oil bath and lubricating system for the moveable parts of the weaving system. The beam includes upstanding lateral cheeks which may support a drive shaft and pivot pins on which oscillating members are moveably pivoted by a drawing system to the heddle frames of the weaving machine.
摘要:
In negative dobbies of the type incorporating swinging lever assemblies to which lever elements are connected and which lever elements support two articulated hooks, retaining members are provided in the form of pivotable locks placed between the bearing face of each hook and the pivot pins by way of which the hooks are mounted to the lever elements.
