Definitions

  • the present invention relates to dobbies and other weaving mechanics of the negative type for the formation of the crowd on weaving machines, and it relates more particularly to the registers of springs which, in this kind of mechanics, ensure the recall of the frames of smooth operated with the latter.
  • each register is thus stretched during the positive control of the frame by the dobby or other mechanism (control which is most often performed by lowering), and, by elastic traction on the corresponding cable, bring back said frame in the initial position (high position in the case considered).
  • search Report cites, in addition to the above-mentioned document, document EP-A-0 071 764 (GEBRUDER SCHMEING).
  • the invention essentially consists in having at the ends of the movable clip linked to the operating cable two lateral pads which are oriented parallel to the springs and whose thickness is slightly greater than the diameter of the latter so that the pads of the staples of two adjacent registers can rub against each other avoiding any contact between the springs attached to said staples .
  • the register shown in 1 in fig. 1 comprises a series or ply of springs 2 hung vertically between two staples 3 and 4.
  • the lower staple 3 of each register is fixed to a rack 5 secured to the vertical structure 6 of the weaving machine, while the upper staple 4, provided movable, is attached to a cable 7.
  • the latter is linked at 8 a to a return lever 8 mounted to oscillate on an axis 9 carried by the structure 6, and it is laterally made integral with a heald frame 10 before hanging onto the corresponding movable member of a dobby or other mechanical of the negative type.
  • the upper clip 4 comprises at each of its ends, beyond the series of openings 4 is intended for the attachment of the folded end 2a of springs 2, a vertical back 4b pierced two superimposed holes 4 c .
  • Each return 4b is adapted to be engaged vertically in the upper forked end 11a of a skate 11, the fixing in place of the latter being effected with the aid of two rivets 12 inserted into the holes 4c aforementioned and in corresponding holes 11 b formed in the forked end 11a of the pad 11 considered.
  • the pads 11 are made of a synthetic material promoting sliding and they are made at a thickness slightly greater than the diameter of the springs 2, so that as shown in FIG. 3, their lateral faces come into contact with the lateral faces of the pads of the contiguous registers 1.
  • the pads 11 of all of the registers 1 guide the movable staples 4 during the alternating vertical movements of the frames 10 of the loom, thereby opposing the effects of cable twisting and by in any event prohibiting any untimely friction of the springs 2 of two adjacent registers.
  • each shoe 11 can vary to a large extent, depending in particular on the amplitude of the stroke of the spring registers. It also goes without saying that any other method of fixing the pads 11 on the ends of the movable staples can be imagined, in particular that illustrated in FIG. 4 where it is assumed that the back 4 'b of the clip 4' was considered profiled so as to clip elastically inside a conjugate opening 11 'is provided in the upper end of each 11 'skate.
