A pulley (1) for installation in a pulley mechanism of a Jacquard machine, comprising a shaft (3); a housing (4), comprising two flank bodies (5), which are provided to fasten the shaft (3), so that this shaft (3) extends substantially between the flank bodies (5); and a pulley wheel (6), which is provided to be arranged between the two flank bodies (5) so as to be directly rotatable around the shaft (3);
wherein the shaft (3), prior to assembly of the pulley (1), is provided with cavities (7, 10, 11) and/or projecting portions for the post-assembly axial securement of the flank bodies (5) in both axial directions.

A shed forming device for a weaving machine comprising motion systems consisting of hooks that are moveable up and down, transmission elements to transmit the hook motion to a carrier for warp threads, a first force element to exert a downward-directed force on the carrier, and an energy buffer and a second force element to exert a force on an element of the motion system that results in an upward-directed force on the carrier so that the element is so deformed or displaced that the elements of the motion system are kept under tension.

This control system (100) for at least one Jacquard mechanism (4) for forming shed comprises electromechanical selection devices (20) including magnets, a primary controller (70) intended to communicate with a weaving machine (2) and including at least one memory (76) to store weave pattern data and at least one computer (74). This system also comprises at least two secondary controllers (40A, 40B), each electrically connected to the primary controller (70) and each able to control a group of electromechanical selection devices (20), each secondary controller comprising at least one memory (46A, 46B) for storing weave pattern data and at least one computer (44A, 44B), as well as control units (30) for the electromagnets belonging to the electromechanical selection devices (20). This system further comprises at least one intermediate controller (50) in direct electrical connection, on the one hand, with one of the secondary controllers (40A, 40B) and, on the other hand, with at least two electromagnet control units (30).
