摘要:
In a reading device for dobby or other weaving mechanism with double swinging levers and retaining hooks, of the type in which said hooks are actuated by a disc with radial lugs or the equivalent, at least one input gear connected for rotation with the shaft of the mechanism and meshing with an intermediate gear carried by a mobile member which can be displaced concentrically with respect to the axis of said input gear, and which intermediate gear meshes with an output gear in turn with the lug disc coupled for rotation and carried by a supporting lever associated with yieldable means operative to maintain said output gear in mesh with the intermediate gear, so that by selectively angularly displacing the mobile member about the input shaft, it is possible either to achieve a simple angular shift of the lug disc to allow for unweaving during reverse motion, or alternatively to achieve the retraction of said lug disc away from the heels of the hooks in order to level all of the heddle frames.

A quick connect coupling for removably connecting two pipes which comprises a male element adapted to fit into a female element along a principal axis of the coupling. The Female element includes at least one ramp for receiving a radial projection of the male element to lock these elements together. The ramp is formed in a ring freely rotatably mounted in the female element, and fixed in translation along the principal axis, while the projection is fixed with respect to the male element. The ramp forms a seat for locking the radial projection. Locking is obtained by essentially axial movements of the male and female elements with respect to one another.

A locking mechanism for a rotary electric actuator for the formation of a shed on a loom wherein the actuator includes a driving rotor for rotating a device for winding and unwinding a harness thread and wherein the actuator includes a locking plate driven by the rotor which interacts with a locking member such that, when a stop of the locking member engages the locking plate, rotation of the rotor is stopped. A control mechanism is provided to selectively maneuver the locking member relative to the locking plate.

In a dobby drawing device in a weaving loom, the vertical displacement of a heddle frame is obtained with the aid of a single cable which is guided over first and second actuating levers to a set of springs. Two support shafts selectively support the actuating levers so the device may have a lifting or descending action.

In a spring system for dobbies and other weaving mechanisms of the negative type which includes hooking elements, each of the hooking elements includes, parallel to its edges which face the springs, a row of omega-sectioned openings which receive, by a lateral displacement along the axis of the opening, an endpiece of a shape to be seated within the openings.

The invention concerns a frame comprising two posts (4, 4′) and two cross-members (6, 6′), a catching member (8, 8′) adapted to receive one corresponding end of at least one heald (10), and damping means (12, 12′) against which at least one end of the heald is urged to be pressed. At least when the frame is stationary, the heald being substantially rectilinear, when one first end of the or each heald (10) is pressed, either on a first catching member (8) at the traction zone (S1) thereof, or on a first damping means (12) at the compression zone (C1) thereof, the other end of the or each heald (10) is pressed, either on other damping means (12′) at the compression zone (C′1) thereof, or on another catching member (8′) at the traction zone (S′1) thereof.

This member for guiding the harness cords of a Jacquard loom harness is substantially planar and provided with holes for passage of the cords. At least one of these holes extends in a direction which is oblique with respect to the principal plane of this member. This arrangement makes it possible to limit the efforts of friction undergone by the harness cords, particularly at the level of the edges of the holes.
摘要:
The frame, which is obtained by assembling two struts (21) with two cross-bars (22) each of which is provided with a heald-carrier rod (29), comprises at least one hoop (40) surrounding a tubular extremity (28) of said cross-bar (22) in an area in which it is joined to the adjacent strut (21) and an area in which at least one locking member (25, 26) of part (21a) of said strut is received. The area of junction is created in part (35) of the extremity (28) provided with an external transverse profile which is essentially convex. The hoop is provided in order to resist a locking effort (F3, F′3) exerted by the locking member (23, 24).

Housings to enclose winding actuators for the vertical control of harness threads of a weaving mechanism are arranged in rows and/or columns to form at least one panel positioned in the upper portion of a weaving loom.
摘要:
A collar for selectively connecting and disconnecting twines and harness cords in a jacquard harness mechansim for a weaving loom. The collar includes a socket element having at least one elastically deformable chuck with jaws for engaging a prong of a male element inserted within the socket element. The male element includes a shuttle which is moveable along a rod which extends from the prong to an intermediate portion of the male element which aligns the male element with the socket element. The shuttle separates the jaws of the at least one elastically deformable chuck during relative axial movement of the male element with respect to the socket element to permit the prong of the male element to be inserted into or withdrawn from engagement with the socket element.
