Definitions

  • This invention relates to a frame-driving unit for weaving looms, especially for looms equipped with a programming unit such as a dobby or the like.
  • the frames are controlled positively from the afore-mentioned programming unit from their lower position to their higher position, wherein they can further be brought back in the low position by means of springs provided therefor.
  • a characteristic known kinematic chain consists e.g. at least of a rocking arm subject to the above-mentioned programming unit; a flexible joint between this arm or lever and a second arm or lever which is supported to a fixed part of the loom; a tie rod between this second lever and a frame; and a spring means that makes contact with the afore-mentioned second lever.
  • the present invention relates to a driving mechanism of the type as described above and in the preamble of the main claim.
  • a programming unit 3 e.g. a dobby, is mounted on girder 1 .
  • a kinematic chain is provided mainly consisting of :
  • Each push rod 10 is hinged in 12 on the corresponding lever 6.
  • the point of contact of spring means 11 on it is indicated by 13.
  • Every lever 6 shows a circular leg 14 to which an extremity of the corresponding flexible connection 8 is fixed, viz. in an outward direction with respect to the centre of girder 1 and the point of rotation 7.
