Definitions

  • the invention relates to a device for fastening a Webblattes on a loading beam of a weaving machine, the Reed an upper profile, a lower one, on the shop beam Profile to be attached and slats arranged in between having.
  • Reinforcing bars made of solid steel provide the appropriate the slats of the reed and parallel to these slats arranged between the upper and lower profile become.
  • Such a reinforcing bar can be straight or have one or more bends. If such Reinforcement bar on the weft insertion side of the reed is provided, the arrangement of the main blowing nozzles and a cutting device for the weft threads difficult, which are arranged directly on the fabric edge or the reed should be.
  • Such a reinforcing rod is on attached to the opposite side of the reed, so this complicates the arrangement of a shotguard or one Stretching device for weft threads, which are also directly on the Side edge of the fabric or on the reed should. In many cases, this leads to a tissue with relative wide waste edges. In addition, streaks can appear in the area of the fabric edges that result in the area a reinforcing bar made of solid steel. At high Web speeds can also be one of such Insufficiently prevent reinforcing rod from the slats of the reed on the lower profile of the Break the reed.
  • the invention has for its object a device of the type mentioned at the outset, with which the danger significantly reduced by breaks in the lamella of the reed can be.
  • the invention ensures that the reed, i.e. in front especially the upper profile and the slats, not in the longitudinal direction swing the reed. This eliminates the risk of Breakage of the slats in the area of the lower profile is already significant reduced.
  • the connecting element is flexible across the reed.
  • the connecting element therefore limits the deformability of the Slats transverse to the longitudinal direction of the reed when struck not on the edge of the goods, so that the slats of the Can deform the reed evenly when struck. This largely prevents streaks in the fabric. As well there is a risk of breakage of the slats in the area of the lower Profiles due to the stress caused by striking significantly reduced.
  • the connecting element is a strip made of metal, which on the upper profile of the reed and at a distance from the end of the Webblattes is attached to the shop bar.
  • the bar made of steel is produced and a thickness across the reed Of the order of 2 mm, parallel to the reed a height in the order of 15 mm and a length of about 100 mm up to about 200 mm.
  • Such a bar ensures that the bar does not bend under the loads that occur can, so that movements of the reed in the longitudinal direction largely prevented. However, movements across this are possible so that the risk of streaking is reduced in the tissue.
  • a bracket on the loading beam in extension of the reed attached to which the connecting element is attached is. This makes the connecting element easier Connected to the shop bar at a distance from the reed become.
  • an air jet weaving machine is expedient provided that at least one on the bracket Main blowing nozzle is attached. If the fastener is opposite the entry page is arranged, it is expedient provided that a shotguard on the bracket and / or a stretching device for weft threads attached are. This ensures that the bracket in addition to Attachment of functionally necessary parts can be exploited can, so that the total number of additional parts is very low is.
  • the reed 1 shown in FIGS. 1 and 2 has one A large number of slats arranged in a row next to each other 2.
  • the slats 2 have a U-shaped shape approximately in their center Recess that together a guide channel 3 for to form a weft.
  • the slats 2 are in an upper one Profile 4 and fixed in a lower profile 5.
  • the slats 2 are both in the upper profile 4 and in the lower profile 5 by means of so-called connecting spirals 7, 8 in one predetermined distance from each other.
  • the slats 2 are together with a connecting spiral 7 and 8 and holding rods 9 and 10 in the upper profile 4 and in the lower profile 5 glued.
  • the lower profile 5 is by means of a feather key 11 and screws 13 attached to a shop bar 12.
  • the shop bar 12 is in a known manner by means of stilts a shop shaft running parallel to the shop bar 12 attached.
  • an elongated connecting bar is on the reed 1 14 attached, which is substantially in the longitudinal direction A of the reed 1 extends and the one movement of the reed 1 in this longitudinal direction A prevented.
  • the Connection bar 14 is in the embodiment on the Weft insertion side of the reed 1 attached.
  • the connection bar 14, which consists for example of steel in the transverse direction B a thickness of the order of 2 mm on. The height is of the order of 15 mm.
  • the connecting strip also has a length of the order of magnitude from about 100 mm to about 200 mm.
  • the end 15 of the connecting bar 14 is at a distance from that Reed 1 connected to the loading bar 12.
  • a fastening part 17 is attached, which by means of a Screw connection 16 is attached to a holder 18, which is attached to the loading beam 12.
  • the attachment takes place according to the fastening of the lower profile 5, namely with the help of a parallel key 19 and screws 20th
  • the bracket 18 is in the form of a bent sheet metal plate, which is still used in an air jet loom like this 1 and 3, one or more main blow nozzles 21, 22 hold.
  • a holder 23 of the two Main blowing nozzles 21, 22 by means of screws 24 on the holder 18 attached.
  • the ends of the nozzle pipes 25, 26 of the main blowing nozzles 21, 22 are by means of a further holder 27 and one Screw 28 also attached to the bracket 18.
  • the end 29 of the connecting bar belonging to the reed 1 14 is attached to the upper profile 4 of the reed 1.
  • a bar 30 in the U-shaped recess of the Profile 4 used which extends from the slats 2 away.
  • This bar 30 is approximately as wide as the upper areas the slats 2 of the reed 1, which in the recess of the upper profile 4 are glued.
  • the bar 30 can therefore corresponding to the slats 2 in the recess of the upper profile 4 can be arranged.
  • the strip 30 closes the first Blade 2A of the reed 1 and at the end of the connecting spiral 7 on.
  • the holding rods 9 run over a certain one Length over the first lamella 2A and the connecting spiral 7 out.
  • the strip 30 is together with the holding rods 9 the upper profile 4 glued.
  • the support rods 9 are welded to the strip 30.
  • a strong one Connection between the bar 30 and the upper profile 4 is required because this connection absorbs relatively high forces got to.
  • the connecting bar 14 is between the bar 30 and the holding bar 32 arranged and by means of a screw 31 held.
  • the bar is preferably 30 made of steel as this is for attaching the connecting bar 14 by means of a screw 31 is advantageous.
  • the connecting bar 14 has a thickness, which is essentially the thickness of the rear leg 33 (Fig. 2) corresponds to the upper profile 4. After tightening the screw 31 then remain the bar 30 and the holding bar 32 in aligned essentially parallel to each other.
  • This construction is particularly suitable for reeds where the upper profile 4 made of aluminum or another relative lightweight metal, which itself has a relatively low strength having.
  • the connecting bar 14 directly by means of a screw on the upper one Profile 4 of the reed 1 attached.
  • This solution is for example then advantageous if the upper profile 4 of the Reed 1 made of steel or another material with relative high strength.
  • FIG. 5 an embodiment is shown, which also offers the advantages already described, but with the one Connection bar 34 on the opposite side of the Reed 1 is arranged, i.e. on the weft entry side opposite side.
  • the connecting bar 34 is corresponding to the embodiment of FIG. 1 with one end 39 with the upper profile 4 of the reed 1 and with his End 40 connected to a bracket 35.
  • bracket 35 which is also a folded sheet metal plate, are a Weft monitor 36 and / or a stretching device 37 for weft threads attached, which is immediately next to the reed 1 are arranged.
  • the shot guard 36 and the stretching device 37 are each by means of a screw 41 and 42 on the Bracket 35 attached.
  • a connecting bar 34 are arranged.
  • the attachment of one or both elongated connecting strips 14, 34 prevents the reed 1 and in particular the upper profile 4 and the slats 2 when weaving in the longitudinal direction A swing.
  • the connecting strips 14 and / or 34 absorb tensile and compressive forces that cause movement of the upper profile 4 to the weft insertion side and in the opposite Prevent direction.
  • the connecting strips 14 and 34 are dimensioned so that they are strong enough to Do not buckle pressure forces. It has been calculated that a connecting bar 14 or 34 with a thickness of about 2 mm and a height of about 15 mm sufficient resistance against buckling when forces act that at a weaving speed of 1,200 shots per minute and occur accordingly many attacks.
  • the elongated connecting strips 14 and / or 34 impair at most to a small extent that the end area 6 of the reed 1 in the area of the main blowing nozzles 21, 22 and / or the end region 38 of the reed 1 in the region of the Shot guard 36 or the stretching device 37 in the transverse direction B move.
  • the mobility of the reed 1 in these Areas 6 and 38 are opposite the middle areas not limited. This is achieved in that the connecting strips 14 and / or 34 are relatively long so that they bending in the transverse direction B is not too great a resistance oppose. This ensures that not due to different mobility of the reed 1 in Transverse direction B stripes or other irregularities in the Area of the fabric edges.
  • the elongated connecting elements 14 or 34 must not necessarily have a strip shape. she can, for example, round or square rods with any Cross-section, but should be designed so that they have a movement of the reed 1 in the longitudinal direction A largely prevent, but the movement of the reed 1 allow in the transverse direction B. It may also be possible as connecting elements ropes, especially steel ropes or plastic ropes.
