Definitions

  • the present invention relates to a computer-controlled modular electromagnetic device for driving warp yarns for making figured fabrics.
  • the required deflection of the lifters, in order to form the shed is made through a complex cooperating needle system, including a plurality of driving and pushing needle members.
  • This needle driving device is rather complex construction-wise, usually requires frequent maintenance operations as well as calibration operations.
  • the aim of the present invention is to overcome the above mentioned drawbacks, by providing a device for selecting and raising warp yarns, on weaving apparatus or machines, which is very simple construction-wise as well as very reliable in operation.
  • a main object of the present invention is to provide a device for selecting and raising warp yarns in weaving machines, which can be operated under the control of a programmed computer or processor means.
  • Yet another object of the present invention is to provide such a device for selecting and raising warp yarns which has a very reduced size.
  • a computer controlled modular electromagnetic device for selecting and raising warp yarns for making figured fabrics, characterized in that said device comprises a pair of rods which can slide along parallel vertical guides, formed on an elongated parallelepipedal body, under the control of conventional driving blade members which are driven with opposite reciprocating movements, said rods jointly restraining, through a flexible coupling member, a first sheave, coupled to a second sheave, said second sheave being coplanar with said first sheave, and operating on a central link element of a heddle link, an electromagnet being moreover provided arranged between said two rods, said electromagnet being power supplied under the control of programmed processor means so as to restrain, through lever arm members, one of said rods.
  • the computer controlled electromagnetic device for selecting and raising warp yarns for making figured fabrics comprises a pair of rods 2 and 2′ which can slide along parallel vertical guides 3, formed on a body 4 having a substantially alongated parallelepipedal shape.
  • said rods are provided, at corresponding opositions, with a respective window 5 and a bottom ridge 6 which can be engaged by driving blade members 7, which are vertically reciprocated.
  • a bottom plate 8 provided, at the top thereof, with a pair of resilient foil members 9 which upward extend.
  • foil members engage with a respective end portion of corresponding lever arms 10, pivoted at 11, which are made of a ferromagnetic material and have a specifically designed perimetrical contour, and being moreover provided with a beak top outer projection 12.
  • the electromagnet is power supplied through a suitable printed board 16 adapted to connect the electromagnet to a driving circuit therefor.
  • the rods support, through a flexible member 17, a first sheave 18 which bears a second sheave 19 engaging the shed forming cord 20.
  • one of the rods 2 or 2′ will engage, during an upward stroke, its corresponding lever arm, through its top beak member 12, so as to cause said lever arm to approach the pole of the electromagnet 13.
  • the resilient foil element 9 will automatically displace the lever arm from the electromagnet (see Figure 3) so as to bring said lever arm to engage in the window 5 of the rod, for preventing the latter from being lowered.
  • a resilient projection 21 can be moreover provided, which will be formed at a set level, said resilient projection or ridge having an inward turned convex configuration.
  • This projection will aid the rods or movable armatures 2 and 2′ to properly abut on the electromagnet poles so as to reduce to a minimum value the energizing current necessary for restraining said armatures.
