  • Each respectively upper and lower 6 '6' is equipped, in known manner, a corresponding fastening member or bar 8, 8 '.
  • These bars 8 and 8 ' which will be described in more detail in the following, allow the attachment of the upper and lower ends respectively of different smooth 10 belonging to the frame 2 of the loom M.
  • FIG. 2 illustrates the attachment of the upper end of a rail 10 to the upper cross member 6, by means of the bar 8. It should be noted that the fixing of the lower end of this rail 10 on the rail 6 ' is performed in a similar manner, by means of the bar 8 '.
  • the structure of the upper cross member 6, which is conventional, will not be described in more detail in the following.

  • This smooth 10 comprises, in a conventional manner, a filamentary element 10 1 , provided with an eyelet 10 2 , visible in Figure 1, for the passage of a not shown warp.
  • the filiform element 10 1 extends into two main branches 3 , defining a housing 4 to receive the bar 8.
  • the outlet of this housing is bordered by two teeth 5 of the rail, extending towards each other, so as to form a neck 10 6 of restricted transverse dimension.
  • attachment region 8 4 has a roughly rectangular cross section, whose dimensions are significantly greater than those of the intermediate region 8 3 .
  • This attachment region 8 4 forms, in its lower part opposite the crosspiece 6, a U-shaped fold 8 5 , whose core 8 51 is turned towards the cross member 6.
  • This fold ensures the retention of a damping element 12, of known type, which is a flexible element made for example of a polymer material, an elastomeric material, or the like.

In this case, when the single damping means 12 or 12 ', integral with the bar 8 or 8' are in contact with the compression surfaces of the end facing the bar, the other end thereof is advantageously in contact, by its traction surfaces S ' 1 or S 1 , with the other facing bar 8' or 8.
  • FIG. 3 illustrates a first variant embodiment of the invention.
  • the mechanical elements similar to those of Figure 2 are assigned the same reference numbers, increased by 100.
  • the crosspiece 106 is hollowed out with a recess 106 1 having, in cross-section, a diamond shape.
  • This recess which is open towards the not shown smooth, opens outward via a neck of reduced transverse dimension.
  • the bar 108 is provided with a fixing region 108 1 , which comprises two L-shaped legs 108 21 and 108 22 , forming the free ends of the folded sheet constituting the bar 108.
  • the attachment region 108 1 can be introduced into the recess 106 1 , by pinching the two branches 108 21 and 108 22 , so that it penetrates through the aforementioned neck. Then, these two branches are pressed against the walls 106 2 of the recess 106 1 , by elasticity and / or prestressing of the constituent plate of the bar.
  • the two branches 108 21 , 108 22 come together in an intermediate region 108 3 , of reduced section, which extends into a region fastening 108 4 .
  • the latter has a generally similar profile to that of region 8 4 of Figure 2, except the fold 108 5 which has a U-shaped section with wings oppositely inclined from one another.

  • the damping element 212 has lateral dimensions greater than those of the hooking region 208 4 .
  • this damping element is provided with two lateral projections 212 1 , delimiting two functional sets denoted J. In service, these projections therefore extend in the vicinity of the branches 210 3 of the rail 210, so as to avoid any contact between these branches and the attachment region 208 4 of the bar 208.
  • the attachment region 208 4 extends, opposite the damping element 212, by an intermediate region 208 3 , similar to those 8 3 and 108 3 described above. Unlike the previous examples, the region 208 1 for attachment to the cross member 206 is formed by a simple extension of the intermediate region 208 3 , without changing the transverse dimensions with respect to the latter.

  • the attachment region 308 4 therefore differs from those of the previous examples in that it is open opposite the cross member 306. More specifically, this attachment region 308 4 has a generally U-shape, whose wings 308 41 and 308 '41 are terminated by recessed flanges 308 5 and 308' 5 , each of which belongs to a corresponding folded sheet 309 or 309 '. These re-entrant edges thus forming folds of the constituent plates of the bar 308, while the damping element 312, which is generally massive, is hollowed out with two notches 312 1 and 312 ' 1 , intended to receive these flanges 308 5 and 308 ' 5 .
  • the hooking region 308 4 extends into an intermediate region 308 3 , which is itself terminated by a region 308 1 , ensuring the attachment of the bar 308 to the cross member 6.

In service, this projection 512 1 therefore bears against the branch 510 3 of the rail 510, so as to avoid any contact between this branch of the rail and the arm 508 4 opposite the bar 508.
  • each of the bars 408 or 508 of FIGS. 6 and 7 is equally suitable for use with healds of different shapes, especially in C or J. Thus, it is only necessary to change the damping element 412 or 512, depending on the use considered.
