Definitions

  • the present invention relates to rotary dobbies for controlling heald frames mounted on weaving looms.
  • This shaft is driven by an intermittent rotation movement and at each stop, that is to say every half-turn of the aforementioned tree, the reading device must, at the level of each of the dobby blades (that is to say the actuation unit associated with each heald frame) and depending on the pattern or weave to be obtained on the fabric being woven, secure the actuating element either with said shaft to control the oscillating part, either with a fixed point in order to operate the angular immobilization of the latter.
  • This selective joining is generally obtained using a mobile coupling mechanism in the form of a key or pawl, subjected to the action of two pivoting levers arranged on either side of the shaft in order to actuate said movable mechanism at the two stop positions thereof, each pair of pivoting levers being placed under the dependence of the reading device of the dobby.
  • the present invention intends to remedy, in order to allow the production of a rotary dobby of the "synchronized" type, capable of operating in forward and reverse directions.
  • the shaft 1 crenellated, carries a drive disc 7 which is integral with it and the periphery of which is cut out by two radial notches 7a, diametrically opposite one another.
  • These notches 7a are intended to selectively receive the terminal finger 8a of a pawl 8 articulated on an axis 9 carried by the lateral plate 3 of the corresponding eccentric 2; a spring 10 tends to permanently recall the finger 8a of the pawl 8 in the direction of the shaft 1.
  • each pawl 8 The control of each pawl 8 is ensured by means of two pivoting levers 11 carried at articulation by fixed axes 12 oriented parallel to the shaft 1.
  • Each lever 11 has a square profile and is biased by a spring 13 in order to come to bear against a corresponding fixed stop 14.
  • These two stops 14 thus define on each lever 11 an actuating tail 11 a, capable of being controlled by pushers (arrows 15) of the reading device of the dobby.
  • each lever 11 has a spout 11 b, diametrically opposite the similar spout 11 b of the other lever relative to the shaft 1; each spout 11b is intended to engage in a notch 3a made radially in a protruding ramp or ear 3b of the plate 3.
  • the rocking pawl 8 carried by the envisaged plate has a heel terminal 8b intended for actuating said pawl by the spout 11b engaged in said notch 3a.
  • the present invention consists in making each of the plates 3 of the dobby have a projecting ramp or ear 3c provided opposite the aforementioned ramp or ear 3b , and to cut in this second ear 3c a notch 3d diametrically opposite to the notch 3a.
  • Figs. 5 and 6 clearly show the profile of the two notches 3a and 3d of the same plate 3 and it will be observed that while the side walls of the notch 3a, relatively deep, are oriented parallel to the oblique sides of the beak 11 b to give a perfectly precise angular position to the plate 3 and then ensure effective retention as long as the contact is maintained, the notch 3d is however established at a reduced depth and has very flared side walls, oriented parallel to the chamfers d end of the sides of the beak 11 b.
  • the invention is capable of being applied to the dobbies in which the actuating elements are no longer constituted by eccentrics associated with connecting rods, but by profiled cams for the control of roller levers coupled to the frames. healds 6.
  • the tilting pawls seem to be the most advantageous embodiment for the mobile coupling mechanism, one can however have recourse to keys with radial displacement.
