It also relates to a loom equipped with such a mechanism. [Prior Art] In the field of passive multi-arms, such as EP-A-0 0 2 7 0 9 5, it is known to produce a stretching mechanism for controlling a heald frame of a loom, wherein a flexible element, such as a rope One end is connected to a pull-back spring or a temporary storage machine, and the other end is connected to one of the components controlled by the multi-arm. The flexible element is continuously supported on the two return levers, and the two return levers are each coupled to a comprehensive frame. The number of flexible elements and their associated sets of rods is as much as the number of heald frames to be driven. Such a known mechanism is relatively complicated because a device for adjusting the shed must be placed in the joint region between the flexible member and the member driven by the multi-arm. Thus, the elements driven by the plurality of arms must be mechanically coupled to a rocker arm in an adjustable manner, and the rocker arm itself is also driven by the multiple arms. This creates a complex and relatively heavy structure that is subject to intense acceleration when the multi-arm is operating. In this type of device, the shed adjustment element is disposed inside the multi-arm. Therefore it is difficult to access. SUMMARY OF THE INVENTION One particular object of the present invention is to provide a new type of stretching mechanism to overcome such shortcomings, which is relatively simple compared to the prior art and allows for simple adjustment of the shed. In accordance with this spirit, the present invention relates to a stretching mechanism for controlling a heald frame equipped with a passive multi-arm loom. For each heald frame, the mechanism 6 312 / invention specification (supplement) / 93- 01 / 9213 0198 1299067 comprises a flexible element extending between a component of the multi-arm actuation and a pull-back spring assembly or temporary storage machine, which is attached to the component, to the component, and to Individually coupled to the return rod of the heald frame. The mechanism is characterized in that the flexible component is directly coupled to one of the arms of the rocker arm, the rod has a fixed oscillation amplitude, and the system is provided with a two-way swinging rod, and the two-way swinging rod is provided with a hooking member, which is suitable for The multi-arm reading device is selectively coupled to achieve the purpose of temporarily fixing the rocker arm, and the flexible member is also coupled to one of the return levers in an adjustable manner such that the flexible member and the aforementioned return force The distance between the pivots of the rods can vary. Because of the invention, the shed adjusting device can be arranged on the multi-arm rod, so it can be greatly simplified. Since the device is offset from the height of one of the return levers, the structure is relatively simple, and the components of the more arms are easier. Close. According to an advantageous but not essential aspect of the invention, the mechanism comprises one or more of the following features: - The rod with a fixed amplitude of oscillation is provided with a shoe for supporting and guiding the flexible element. The flexible element is adjustably coupled to the return rod, the return rod being provided with a stirrupe element movable relative to the rod and secured to the flexible element. Thus, the extension may advantageously extend substantially in a direction perpendicular to the direction of the flexible member between the rocker arm and the return lever - the flexible member is formed by a plurality of portions that extend respectively Between the rocker arm and the first return lever, between the two return levers, and between the second return lever and the pullback spring assembly. 312/Invention Manual (Supplement)/93-01/92130198 7 1299067 - The middle of the multi-arm is provided with a plurality of rocker arms hinged to a common shaft, and the connecting area of the flexible element on the rod and the shaft The distance between them and the same for all of these rocker arms. The rocker arm can be divided into at least two groups. In the group, the distance between the fastening region of the flexible element and the common axis is equal, and the aforementioned distance between one group and another group may be different. In particular, the distance value can be increased from the front side to the back side of the shed. The mechanism is supported by an upper structure comprising a beam having a substantially U-shaped cross section that is substantially upwardly open and disposed substantially above the heald frame in a substantially horizontal direction. The invention also relates to a loom incorporating the aforementioned stretching mechanism. This machine is more reliable and less expensive than conventional techniques. Other advantages of the invention will be apparent from the description of the two embodiments of the present invention and the accompanying drawings. [Embodiment] The loom shown in Figs. 1 to 3 includes a passive multi-arm 10 provided with a rocker arm 11 pivoted to a common shaft 12. In Fig. 1, only one rod 1 can be seen in its entirety. The cover 1 3 of the multi-arm 10 has been partially removed, and a second rod 1 1 ' can be seen separately. The rod 1 1 is provided with a two-way oscillating rod 14 having a hook member 15 for cooperating with a positioning hook member 21 controlled by a control unit 22. The element 2 1 and the reading device 20 belonging to the multi-arm 1 are. The other rods 11' and their equivalent members are similarly provided with a two-way swing lever, and a hook member is provided for engaging the reading device 20. As indicated by the double-headed arrow F!, the rod 1 1 and its equivalent members are pivotally connected to the 312/invention specification (supplement)/93-01/92130198, respectively, and the corresponding finished portion is 22-axis 1229967 12, and has a fixed amplitude of oscillation. By the cooperation of the hook members 15 and 21, they are selectively held near the dead centre of their stroke. The flexible cord 30 is coupled to each of the rods 1 1 and their equivalent members, such as the rod 1 如图 shown in FIG. The cord extends from each rocker arm 1 1 or 1 1 ' toward the first return lever 40 and is then extended from there to a second return lever 50 and is similarly coupled to the second return lever 5 0. The rope 30 extends from the rod 50 to a component or temporary register 60 which includes a spring 6-1 for resiliently returning the rods 1 1 , 40 and 50 to a predetermined position towards one of the elements. The path of the rope 30 is a straight line between the rods 1 1 and 40, between the rods 40 and 50, and between the rod 50 and the assembly 60. In this way, it is not necessary to provide a return pulley on the path of the rope 30 except for the rods 40 and 50. Each of the rods 40 and 50 is connected to the frame 70 by two connecting rods 41 and 4 2, 51 and 5 2, respectively, and the frame 70 is provided with a heald 71, only a part of which is shown in the drawing. 7 1. In practice, the rope 30 is formed by a plurality of portions, that is, a first portion 31 extending between the rods 1 1 and 40 and a second portion extending between the rods 40 and 50. And a third portion 33 extending between the rod 50 and the spring assembly 60. The portions 3 1 to 3 3 together form a flexible member, i.e., the member 30 extending between the rod 1 1 and the assembly 60, continuously supported on the rods 40 and 50. The first end 311 of the portion 31 is provided with a loop 312 at a height suitable for fitting one of the hooks 1 1 2 provided on each of the rods 1 1 and their equivalent members. Each of the rods 1 1 and their equivalent members are also provided with a shoe 1 1 1 which is made of 9 312 / invention specification (supplement) / 93-01/92130198 1299067 elastomer or other material. In order to support and guide the rope 30. Each sheath Π 1 is substantially in the form of a segment centered on the axis 12. In a variant, the sheath 1 1 1 may also be centered on the intermediate axis between each sheath 1 1 1 and the shaft 1 2 . At its opposite end 3 1 3, the portion 3 1 is attached to a second sheet 3 1 4 which is hinged to a cookware element 315 which is slidable over a handle 43 and the handle 4 3 Extending from the main portion 4 4 of the rod 40 toward the direction A - A ', the direction A-A' is substantially perpendicular to the axis of rotation 45 of the rod 40 and perpendicular to the direction B of the rope 30 between the rods 11 and 40 - B'. 43a and 43b represent the opposite edges of the shank 43, which are parallel to each other and parallel to the direction A - A '. The double-headed arrow F2 represents the possible sliding direction of the cookware element 315 on the shank 43. The cookware element 3 1 5 is equipped with a screw 3 1 6 for applying a fixing force F 3 of the cookware element 3 1 5 along the shank 43 . The distance d between the portion 3 1 of the element 30 and the shaft 45 can be changed by sliding the cookware element 3 1 5 along the shank 43. In this way, the force application point of the traction force F 4 exerted by the portion 31 of the rope 30 on the rod 40 can be shifted more or less with respect to the shaft 45, which makes it possible to adjust the rod 40 with The stroke of the frame 70 controlled by 50 is adjusted to adjust the shed obtained by the loom. The portion 3 2 is coupled to the rods 40 and 50 by their two ends 3 2 1 and 3 2 2, respectively. As for the portion 3 3 , the two ends 3 3 1 and 3 3 2 are respectively coupled to the rod 50 and the assembly 60, and the assembly 60 is disposed between the rods 40 and 50. 10 312/Inventive Manual (Repair)/93-01/92130198 1299067 The main part 4 4 of the rod 40 is made of steel. It is formed in a body shape with the handle 43. The portion 4 4 is provided with a section 46 for supporting the vicinity of one end 3 2 1 of the portion 3 2 of the rope 30. This section can be made of a synthetic material. A hook member 4 7 is also provided on the portion 44 for coupling the portion 32. Section 4 6 defines a region Ζ 4 of the rod 40, and a portion 3 2 of the element 30 extends from the region Ζ 4 to the region Ζ 5 of the rod 50, and one end 3 2 2 of this portion is adjacent to the region Ζ 5 . The region Ζ 4 is located between the axis 45 and the frame 70, that is, below the axis, and the region Ζ 5 is disposed above the shaft 45, that is, opposite to the frame 7 with respect to the axis 5 5 position. Rod 50 also defines a second region Ζ '5 between axis 5 5 and frame 70, and portion 3 3 extends from region Ζ '5 in a direction that is substantially perpendicular to the direction of vibration of frame 70. -Ζ'. Due to the distribution of the regions Ζ4, Ζ5 and Ζ'5, the portions 32 and 33 constituting the rope 30 do not cross the connecting rods 41 and 51, so that a width having good mechanical properties can be produced. In practice, the rod 50 is formed with two sections 5 6 and 5 6 ', which are made of a composite material, defining regions Ζ5 and Ζ'5, and after arranging one between the two sections 56 and 56' Metal insert. Considering its geometry, rods 40 and 50 can be considered "pulley-lever". As described above, the adjustment of the shed formed by each frame 70 is achieved by moving the cookware element 3 15 at the extension portion 4 3 , and the cookware and the extension portion are easily located above the heald frame. Close to. After the desired adjustment is achieved, that is, after the distance d between the rope 30 and the shaft 4 5 is defined, the cookware element 3 1 5 is fixed by the screw 3 1 6 11 312 / invention specification (supplement ) /93 -01/92130198 1299067 on the handle 4 3 . In order to facilitate this adjustment, the handle 43 can be provided with a scale (not shown). The shed adjustment of one frame and the other frame may be different. In order to avoid that the shank 43 provided on each rod 40 is too long, the rod 11 and its equivalent members may be arranged in two sizes, that is, the geometry thereof is between the two groups of rods. The pivot radius R of the sleeve 1 1 1 with respect to the shaft 1 2 is not the same. In the embodiment of the drawings, the rods are divided into two groups, that is, the sheath 1 1 in the form of the rod 1 1 has a relatively small pivot radius R, and the corresponding radius R' of the rod 1 1 ' is relatively large. . In practice, a rod having a larger radius R ′ is attached to the rear side of the shed, that is, on the beam side of the loom. The aforementioned elements are supported by a beam 80 having a major axis X - X ' horizontally disposed above the frame 70 of the loom and provided with an opening 8 4 for the connecting rods 41 and 51 to pass through. More clearly, Figure 2 shows that the beam has a substantially open U-shaped cross section, and the pivot 45 of the return lever 40 is supported by the two side nets 8 1 and 8 2 of the beam. Similarly, the pivot 5 5 of the rod 50 is supported by the side net of the beam 80. A rod 6 2 extends between one end 8 3 of the beam 80 and the assembly 60, and is provided with a system 63 for adjusting the tension of the spring 61 to adjust the assembly 60 in each flexible rope The elastic force generated on 30. In the second embodiment of the present invention shown in Fig. 4, elements similar to those of the first embodiment are denoted by the same reference numerals. The substantial difference between this specific example and the previous specific example is that the second portion 3 2 of the flexible cord 30 extends from one of the back levers 40 of the 12th 312/invention specification (supplement)/93-01 /92130198 1299067 The zone Z4 is formed between the second zone Z5 formed by the second return lever 50 - the section 56, wherein the zone Z4 is similar to the first specific example, and the zone Z 5 is located at the pivot 5 5 of the lever 50 and the frame Between 7 0. In this way, the portion 3 2 is substantially perpendicular to the oscillation direction Z - Z ' of the frame 70. Furthermore, the spring assembly 60 disposed between the rods 40 and 50 is connected to the rod 50 by a portion 3 3 extending between a region Z'5, the region Z'5 being relative to the shaft 5 5 is located opposite the frame 70 and is formed by the second section 56' of the rod 50. Portion 33 is substantially perpendicular to direction Z' between elements 50 and 60. As described above, a cookware member 31 5 is fastened to one end 3 1 3 of the portion 31 of the member 30, and the cookware member 3 15 can be slid along a handle 4 3 formed by the rod 40 such that the rod The distance d between the pivot 4 5 and the rope 30 can vary.
