Definitions

  • the present invention relates to a heald frame for a weaving machine equipped a heald damping device, this frame comprising an upper profile provided an upper smooth rod, a lower profile provided with a rod bottom rails, two lateral uprights assembled to said profiles to form said frame and weaving healds mounted on said heald rods by their loop-shaped ends, the heald damper being mounted on the at least one of the profiles of the heald frame and positioned in an existing gap between said profile and the rod carry smooth so as to cushion the head of the loops smooth.
  • the invention also relates to a heald damping device intended for equip a heald frame.
  • the ends of the weaving healds have a loop shape and are mounted on the smooth rods with an imposed operating clearance of approximately 3 mm. This play is necessary for several reasons.
  • the introduction of warp threads in the eyelet of the weaving heddles is generally carried out automatically by a adequate retracting machine, this game allowing the healds to line up automatically.
  • the weaving heddles must be able to slide freely along the smooth rods to allow the weaver to intervene in the chain son ply, for example to repair a wire after breakage.
  • This game is also necessary to avoid any risk of blockage of the beams in relation to smooth rods taking into account manufacturing tolerances and the effects of expansion.
  • the very strong excitement of the frames in vibration mode requires the presence of this operating clearance without which the ends of the beams of weaving would break very quickly.
  • the heald frames evolve like a mass structure variable with the effect of chain tension and the effect of inertia, sometimes the beam 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 full back and forth, there is shock and rebound at the loops smooth. With the speeds reached today, these very strong shocks cause a premature wear of the smooth door rods and untimely breaking of the buckles smooth.
  • the solution proposed in publication JP-A-10 001844 provides for a device mounted between one of the profiles of the heald frame and the heald heads in the form a brush. This device makes it possible to limit the lateral displacement of the beams but in no case of damping the movement in vertical translation of the beams.
  • Publication WO-A-01/48284 also proposes a solution by reporting a damping element directly on the profiles of the heald frame, these profiles being commonly made of extruded or extruded aluminum alloy.
  • This solution does can be envisaged only with profiles made of a metallic material which have a controllable and acceptable straightness in order to guarantee a play of operation between the boom heads and the constant damping element over the entire frame length.
  • this solution is not at all suitable for profiles heald frame made of composite materials (carbon fibers or others) including the straightness is much less good.
  • the operating clearance between the heald heads and the damping element cannot be constant over the entire frame length, the boom of a composite material profile reaching for example 4 mm by 3 m in length.
  • this solution does not allow adjust the clearance between the damping element and the heald heads, in particular to lock the heddles in normal operation of the loom.
  • the purpose of the present invention is to overcome these drawbacks by proposing a simple shock absorber device, easy and quick to install, respecting the play of operation of the weaving heddles, in no way affecting their freedom of movement on the smooth rods, which can be mounted as a kit on frames heald already existing and particularly suitable for heald frames made in composite materials.
  • a heald frame as defined in the preamble and characterized in that that the damping device comprises a support profile extending over the entire length of said heald frame profile and comprising at least one flexible element extending over the entire length of the support profile and forming a stopper arranged in look of said head of heald curls.
  • This damping device is particularly designed to provide a clearance J 'between said damping device and the head of the heald loops lower than the clearance operation J between the healds and the heald rods.
  • the damping device may include means for adjusting said clearance J ′, these adjustment means possibly comprising at least one profile intermediate mounted in said support profile, an adjusting member being arranged between them and movable between at least one position called “with play” and a position called “Without play”.
  • the support profile or the intermediate profile preferably has a groove longitudinal arranged to receive by interlocking said flexible element, which can be interchangeable.
  • This flexible element may have an inverted T section, the leg of the T being arranged to be housed in said longitudinal groove by socket and the branch T having a profile opposite said head of the heald loops in hollow, in relief or plan.
  • the flexible element may also have a circular section arranged to be housed in said longitudinal groove by interlocking.
  • the support profile is fixed integrally to said profile by bonding.
  • the positioning template can include a positioning template arranged to precisely position said support profile on said profile before bonding while respecting the clearance J ′.
  • the positioning template has positioning clips, each provided of two notches corresponding respectively to said support profile and to said smooth rod.
  • the support profile and the smooth support rod can be formed in one piece.
  • the clearance J ' is determined by said support profile.
  • the heald frame may include two shock absorbers provided respectively on the upper profile and on the profile lower of said heald frame.
  • a heald damping device characterized in that that it comprises a support profile provided with a longitudinal groove arranged to receiving by interlocking a projecting flexible element forming a stop for the head heald curls.
  • it may include a positioning template arranged to precisely mount said support profile on the heald frame in respecting the clearance J ', this template consisting of positioning clips, each being provided with two notches arranged to receive the profile respectively support and the smooth rod.
  • the support profile may include a side wall from which a smooth rod protrudes, the clearance J 'being determined by said support profile.

  • This heald frame 1 is preferably made of composite materials, for example based on carbon fibers, glass or other fibers. Composite materials have the advantage of giving the heald frame 1 a excellent mechanical resistance to fatigue while considerably reducing its weight. Of course, the heald frame 1 can be made of any other suitable material. The method of assembling said heald frame 1 is not detailed since it is not the subject of the present invention.

  • This rod carries smooth 3 receives the loop upper 9 of the stringer 8, which has a C shape and is commonly called "tex boom loop". Between the upper edge of the heald rod 3 and the edge lower section 12 of profile 2 there is a gap 14 sufficient to accommodate it said damping device 20. It is therefore positioned above the head of the loop of the heald 9 and is designed to absorb the shocks of the weave heald 8.

  • the damping device 20 introduces a clearance J 'of approximately 0.5 to 1 mm visible between the damping device 20 and the head of the heald loop 9. Thanks to this configuration, the damping device 20 does not hinder not the freedom of the weaving smooth 8 in static mode, which remains mobile along the rods 3 and 5. It is only in dynamic mode that the damping device 20 is used and fully fulfills its role by limiting the operating clearance J of the boom 8 at clearance J 'and by damping the head of the heald loop 9 if the heald travel is greater than 1mm.
  • the damping device 20 comprises a profile support 21 of small section and extending over the entire length of the upper profile 2 heald frame 1. It is, for example, made of extruded aluminum or in any other equivalent material. It has an approximately square section and dimensions such as to be housed in the interval 14. It has in its lower edge a longitudinal groove 22 for receiving a flexible element 23 forming a stopper, made for example in a polymer, an elastomer, a composite material or any other equivalent material, chosen to resist vibration frequencies and to the efforts to bear.
  • This stopper 23 may have an inverted T section, the leg of the T being housed in the longitudinal groove 22 by fitting and the bar of the T being curved for example to approximate the roundness of the top of the heald loop 9.
  • the contact surfaces between the stopper 23 and the support profile 21 are perpendicular to the orientation of the heddle 8 and therefore to the orientation of the shocks for avoid any risk of accidental release of the stopper 23 from the groove longitudinal 22.
  • the support profile 21 is an integral part of the profile superior 2 and remains permanently.
  • the stopper 23 can easily be put in and out of the groove 22 when it must be changed, without any difficulty.

  • This stopper 24 has a circular section but can also have a conforming section to the buffers 23, 25 or 26 described with reference to Figures 2, 4 and 5.
  • This intermediate section 220 has a rib 221 in the shape of an inverted L, this rib being housed in an inverted G-shaped rail 211 formed in the profile support 210.
  • a flexible cord 222 for example made of elastomer, is inserted between the bottom of rail 211 and rib 221 and an adjusting member 223 is positioned between the the branches of L and G respectively of the rib 221 and of the rail 211.
  • This member adjuster 223 has an elliptical shape and is coupled to a control member (not shown) which allows it to be moved between two stable positions: a position called "with play” and a position called "without play".
  • the control unit can be manual and operated by the weaver or automatic and linked to the operating mode of the loom.
  • the largest diameter of the adjusting member 223 is oriented vertically, which goes up the intermediate profile 220 inside the support profile 210 and provides a clearance J ' between the stopper 24 and the heads of the heald loops 9 '.
  • This position is particularly suitable for easily and quickly retracting smooth 8 as well as the retraction of the chain son by a retraction machine automatic.
  • the largest diameter of the adjusting member 223 is oriented horizontally, which descends the intermediate profile 220 outside the support profile 210 and eliminates the play J ' between the stopper 24 and the heads of the heald loops 9 '.
  • This position is particularly suitable during normal operation of the loom.
  • the heads of the upper heald loops 9 ′ are thus blocked in vertical translation this which makes it possible to reduce even more effectively the breakage of the heald loops and the noise pollution due to vibrations.
  • clearance J is kept between the heald loops 9, 9 'and the bottom heald rod 5, which allows the weaver to intervene between the beams if necessary, the beams being able to pivot around their upper fixed point.

  • the heald frames remain fully compatible with automatic wire take-in machines chain and with the requirements of the weavers concerning the mobility of the heddles.
  • Another advantage lies in the very design of the damping device 20, 20 ', 200 by a support profile 21, 21 ', 210 attached to the profile (s) 2, 4 of the frame smooth 1 and not directly integrated into these profiles.
  • This original construction allows to make the damping device 20, 20 ', 200 fully compatible with heald frames made of composite materials, for example based on carbon, glass fiber or other fibers.
  • the support profile 21, 21 'being made of a spun or extruded metallic material has a straightness perfectly controlled which compensates for the lack of straightness of the profiles 2, 4 of the heald frame 1 encountered with technical materials.
  • Figures 11 and 12 schematically represent a profile 2, 4 of heald frame 1 made respectively of metallic materials and composite materials.
  • the extruded or extruded profile 2, 4 for example in an aluminum alloy has perfect linearity to within a few tenths.
  • the interval 14 existing between the section 12 of the section 2, 4 and the rod smooth door 3, 3 ', 5 is constant over the entire length of the profile 2, 4 ranging from 1m to 4m.
  • the profile 2, 4 extruded or spun in composite materials has a linearity defect intentionally exaggerated.
  • the interval 14 is variable over the entire length of the profile 2, 4 and the rod smooth 3, 3 ', 5 produced by rolling a metallic material ensures this linearity essential for beams 8.
  • heald frame 1 It is important to remember that the function essential of the profiles 2, 4 of a heald frame 1 is to provide the mechanical strength to bending of the smooth door rod 3, 3 ', 5 while reducing the weight of the frame and increasing its capacity for resistance to mechanical fatigue. This is why heald frames made of composite materials allow this function to be fulfilled in a completely efficient and optimal way.
  • This new damping device 20, 20 ', 200 avoids this inconvenience thanks to the principle of the adjustable play on the upper rod and in particular in its “play-free” position for the device 200.
  • This damping device 20, 20 ′, 200 can of course be offered for sale or directly integrated into new heald frames, either as a kit to equip already existing heald frames.
