Definitions

  • the present invention relates to a stringer frame for an equipped weaving machine of a smooth damper device, this frame comprising an upper profile provided with an upper smooth door rod, a lower profile with a door rod lower rails, two lateral uprights assembled to said sections to form said frame and weaving rails mounted on said smooth door rods by their ends in the form of a loop, the damping device being mounted on least one of the profiles of the frame and positioned in a gap between said profile and the door rod smooth in such a way as to damp the head of the loops of smooth.
  • the invention also relates to a smooth damper device for equip a smooth frame.
  • the ends of the weaving rails have a loop shape and are mounted on the smooth door rods with an imposed operating clearance of about 3 mm.
  • This gambling is necessary for several reasons.
  • the introduction of the warp threads in the eyelet of the weaving smooth is usually performed automatically by a Adequate tucking machine, this game allows the rails to line up automatically. Once threaded, the weaving rails must be able to slide freely along the smooth door rods to allow the weaver to intervene in the chain son ply, for example to repair a wire after breaking.
  • This game is also necessary to avoid any risk of blockage of the rails compared to smooth door rods taking into account manufacturing tolerances and the effects of expansion.
  • the very strong excitement of vibratory frames requires the presence of this operating set without which the ends of the rails of weaving would break very quickly.
  • the hoop frames evolve as a mass structure variable with the effect of chain tension and the effect of inertia, sometimes the smooth is in support on the upper rod, sometimes it is supported on the lower rod, sometimes it is free between the two support positions.
  • the frame cycles complete back and forth, there are shocks and rebounds at the loops of smooth. With the speeds reached today, these very strong shocks cause a premature wear of smooth door rods and inadvertent breakage of smooth.
  • the solution proposed in the publication JP-A-10 001844 provides a mounted device between one of the profiles of the stringer frame and the stringer heads in the form of a brush. This device makes it possible to limit the lateral displacement of the rails, but no case of damping the movement in vertical translation of the rails.
  • Publication WO-A-01/48284 also proposes a solution relating directly a damping element on the profiles of the stringer frame, these sections being commonly made of spun or extruded aluminum alloy.

  • this solution is not at all suitable for smooth frame profiles. made of composite materials (carbon fiber or other) whose straightness is much less good.
  • the operating clearance between the smoothing heads and the damping element can not be constant over the entire length of the frame, the arrow of a section made of composite materials that can reach, for example, 4 mm 3 m in length.
  • this solution does not allow to make a game adjustment between the damping element and the smoothing heads, in particular to lock the rails in normal operation of the loom.
  • the object of the present invention is to overcome these drawbacks by proposing a shock absorber device simple, easy and quick to set up, respecting the game of weaving machines, in no way affecting their freedom to movement on the smooth door rods, which can be mounted as a kit on frames of smooth already existing and particularly suitable for smooth frames made of materials composites.

It is important to remember that the function essential sections 2, 4 of a smooth frame 1 is to bring the mechanical strength to the bending of the smooth door rod 3, 3 ', 5 while lightening the mass of the frame and increasing its resistance to mechanical fatigue. That's why Smooth frames made of composite materials make it possible to fulfill this function in a very efficient and optimal way.
