Abstract: A textile machine (4) for a weaving loom having an input shaft which is coupled to a weaving loom. The drive mechanism is driven by the input shaft to move frames or collars of the weaving loom through a sequence of predefined positions. The electronic control device is programmed to monitor the change in position of each frame or collar during each step of the predefined sequence of positions and to count the number of times each frame or collar reproduces a particular configuration.

Abstract: A pulling mechanism for controlling the heald frames of a loom equipped with a shedding machine includes a set of connecting rods and oscillating levers (72) coupled to the set of connecting rods, for each heald frame, for returning a movement of the shedding machine to the heald frame. The pulling mechanism includes at least one measuring portion (72C), equipped with a target (100) configured to interact with a sensor (110). For easier mounting and dismounting of the targets on the measuring portions, each measuring portion is provided on a peripheral wall of one of the oscillating levers (72), or a stabilizer of the pulling mechanism, the target being reversibly mounted on the measuring portion (72C).

Abstract: Output lever (11) with cam follower rollers, where the lever has two follower rollers (24A, 24B) connected to a body (110). The body defines a median plane (P11) which has a central portion (116), with two opposing surfaces (117A, 117B), and two attachment portions (122A, 122B), each connected, by means of a respective attachment device (28), to a respective follower roller. Each attachment device has an inner fastener (28A) and an outer fastener (28B), each of which has one or more flanges (30, 32, 34; 30, 32, 34, 70). The flanges are each formed in a plate and bear bears in parallel planes against each other. Each follower roller is clevis-mounted between the inner and outer fastener so that contact surfaces (S242) of the two follower rollers are located on either side of the median plane.

Abstract: Bearing for a shed-forming machine or a system for transmitting movement to the frames of a loom, which has an inner ring, an outer ring and rolling elements. The inner ring is centered on a major axis, has two lateral surfaces normal to the major axis, and defines a circular peripheral path centered on the major axis. The outer ring defines an inner path, which is circular and centered on the main axis. The rolling elements are interposed, radially with respect to the main axis, between the peripheral ring and the inner ring, to guide the outer ring in rotation relative to the inner ring around the main axis. The inner ring has at least one slot, opening onto the two lateral surfaces, extending opposite a portion of the peripheral path, and forms a bridge of material between the slot and the peripheral path.

Abstract: Bearing (25) for a shed-forming machine or a system for transmitting movement to the frames of a loom, which comprises an inner ring (72), an outer ring (74) and rolling elements (76). The inner ring is centered on a major axis (A72), has two lateral surfaces normal to the major axis, and defines a circular peripheral ring (80) centered on the major axis. The outer ring (74) defines an inner ring (82), which is circular and centered on the main axis. The rolling elements (76) are interposed, radially with respect to the main axis, between the peripheral ring and the inner ring, so as to guide the outer ring in rotation relative to the inner ring around the main axis. The inner ring (72) comprises at least one slot (90), opening onto the two lateral surfaces, extending opposite a portion of the peripheral ring (80), and forms a bridge of material (94) between the slot and the peripheral ring.

Abstract: A machine for forming the shed of a weaving loom, of the dobby or cam machine type utilizes output levers performing, during the weaving, an alternating oscillation movement around another common shaft, a casing (12) with an output aperture crossed by the levers, as well as a frame (6) which delimits, with the casing (12), an inner volume (V) of the machine, including an area for receiving torque transmission members between a driving shaft and a shaft for actuating the output levers as well as an area for receiving the output levers, this receiving area being adjacent to the area for receiving the torque transmission members, while the frame (6) supports the actuation shaft. The casing (12) and the frame (6) are in sealed contact, via at least one seal gasket (16, 18), at both external (16) and internal (18) seal barriers (B1, B2) respectively distant from each other, both seal barriers each extending over the whole periphery of the casing (12) except at the output aperture.
