  • Patent number: 4537228
    Abstract: In a weft presenting device for weaving looms with continuous weft feed, the levers controlling the presenting needles are subjected, on one side, to the constant action of return springs towards the inoperative position of said needles and, on the other side, to the cyclic action of cam-controlled control rods towards the operative position of said needles, the levers being kept in this position by electromagnets energized by the selection devices forming the pattern of the fabric being woven, up to operating said needles.

  • Patent number: 4298034
    Abstract: A device for presenting the weft in weaving looms comprising a plurality of oscillating presenting rods having their free end in the form of an eyelet for the weft thread, a corresponding plurality of control levers for the rods, magnet means for causing the oscillation of the control levers under the control of a weft selection device, and a transversal bar for operating the levers being adapted to engage an appropriate seat of those of the levers having been selected by the selection device through the magnet means - the transversal operating bar has a flattened section with mixed-line contour, adapted to freely insert itself into the seat of the control levers of the device, the seat having a corresponding mixed-line contour section, and to respectively cooperate with the seat (like a pin in a hole), depending on the reciprocal position between the transversal bar and the seats of the levers; and the bar is fixed to an end of at least one guide lever which controls the position thereof during its movements
