Abstract: A shed forming device for a weaving machine includes at least one rotary electric actuator for winding, around a pulley, a funicular element controlling at least one heddle and wherein an output shaft of the actuator rotates around a first axis and wherein the output shaft is provided with a pinion meshing with a toothed crown secured to the pulley and rotatable therewith around a second axis perpendicular to the first axis.

Abstract: This shed forming device for a weaving machine comprises at least one rotary electric actuator (112) provided for winding, around a pulley (126), of a funicular element controlling at least one heddle. An output shaft (114) of the actuator (112) rotates around a first axis (X114). The shaft (114) is provided with a pinion (116) meshing with a toothed crown (124) secured to the pulley (126) and rotatable therewith around a second axis (Y126) perpendicular to the first axis (X114).

Abstract: A loom having a subassembly including heddles, a beater, and a device for inserting weft into a shed formed by warp yarns and also including a shed-forming device and a lubrication system for lubricating certain components of the subassembly including a first circuit for circulating a first lubricant and a second circuit for circulating a second lubricant for lubricating the shed forming device. The loom includes a heat exchanger system for exchanging heat between the first lubricant and the second lubricant without fluid communication between the lubricants.

Abstract: The loom (1) comprises a subassembly (2) including heddles (212), a beater (23), and means (25, 26) for inserting weft into the shed formed by warp yarns. It also includes a shed-forming device (4), means for lubricating certain components (22, 24, 25, 26, 28, 29) of the subassembly, said means including a first circuit (C1) for circulating a first lubricant, and means for lubricating the shed-forming device (4), these means including a second circuit (C2) for circulating a second lubricant. The loom (1) includes a heat exchanger system (6) for exchanging heat between the first lubricant and the second lubricant without fluid communication between the lubricants. The heat exchanger system (6) has means (631, 632, 641, 642, 651, 652) for circulating one of the two lubricants or a coolant fluid to a zone (62) of thermal contact with the other lubricant.

Abstract: A weaving loom having self-contained assemblies that operate pulling systems for controlling heddle frames wherein each assembly includes at least one electric motor housed in a casing and at least one motor control unit having an electrical circuit for controlling electric power to the electric motor and wherein the self-contained assembly also includes a support on which the motor control unit is mounted and the support having at least one cooling duct extending there through. The self-contained assembly having damping elements providing a damping effect between the support and the electric motor.

Abstract: The invention relates to a shed-forming device for a weaving loom equipped with several heald shafts or heddle frames and comprising a pulling system connected, for each heddle frame, to a self-contained assembly intended to operate the pulling system and comprising at least one electric motor unit housed in a casing (42) and at least one electrical circuit (54A, 55) intended to transmit in particular the electric power to the electric motor unit, characterized in that the self-contained assembly (E) also includes a support (51) placed close to the electric motor, the electrical circuit (54A, 55) being mounted on the support (51), while the support (51) has at least one cooling duct (51D, 51E) for the flow of a heat-transfer fluid. The self-contained assembly (E) includes damping elements (66B, 80A) placed so as to provide a flexible link between the support (51) and the electric motor unit (40A).
