Definitions

  • the invention relates to a rapier weaving machine with guide means according to the preamble of the claim.
  • Guide means are known from EP-A 0 576 854, each a first guide element, the bottom of a Gripper belt and / or a guide part of a gripper assigned and each have a second guide element, that with the top of the gripper belt and / or the Guiding part of the gripper works together.
  • the invention has for its object a rapier weaving machine according to the preamble of the claim improve.
  • the first and second guide elements of the guide means are spaced apart in the longitudinal direction of the shed, so that the guide elements for machining are easily accessible. In the installed condition of the guide means however, there are first guide elements and second guide elements on top of each other so that they have the gripper belt and / or lead the guide part of the gripper between them.
  • the rapier weaving machine shown in FIGS. 1 and 2 has two gripper belts 1, each with a gripper 2 or a slave gripper 3 has been attached. That with drive means 4 driven gripper belt 1 moves the encoder gripper 2 with the weft thread to be inserted in the longitudinal direction A to the middle of the rapier weaving machine, where the slave rapier 3, which is also driven by a drive means 4 Gripper belt 1 is moved, the weft takes over and on the opposite side of the rapier weaving machine transported.
  • the drive means 4, which are in the range of Side frames 5 are arranged, for example Drive elements driven gears 6, which with the Work the gripper belts 1 together.
  • the permanent contact of the Gripper belts 1 with the gears 6 is by guide wedges 7 causes.
  • the rapier weaving machine also has a comb drawer 8 on which a reed 9 is provided, and which in the Side frames 5 supports and with drive means 10 is driven.
  • the drive means 10 and the drive means 4 can be driven synchronously.
  • the gripper belts 1 In the field of Side frames 5, the gripper belts 1 by fixed arranged guides 11 out.
  • the rapier weaving machine also shows schematically Shed formation means 12, that of shed drive means, not shown, which are synchronous with the comb drawer drive means can be driven, ordered. Further two warp thread surfaces 13 and 14 are shown between which a shed 15 is formed to allow one Enter weft thread. These warp thread surfaces 13 and 14 are formed with the help of subject education means 12.
  • the comb drawer 8 has a drawer axis 16 on which a Shop profile 17 has been fastened with screws. On the shop profile 17 the reed 9 with fastening means 18 attached. There is also an intermediate profile 21 on the shop profile 17 attached with screws to which the invention Guide means 23 have been attached. This attachment takes place with the help of screws 22, which are in the intermediate profile 21 slots provided and the one with cooperate with the guide means 23 provided thread.
  • the guide means 23 serve to guide the gripper belt 1 and / or a guide part 24 for the gripper.
  • the Guide part 24 forms a widening of the gripper belt 1 and is in the area of both the gripper 2 and the Slave gripper 3 provided. These guide means 23 can with the help of the movement of the comb drawer 8 in and out of the Move shed 15.
  • the guide means 23 are located as has been shown with a dashed line in Fig. 2 is in a position where a registered weft is struck on the stop line 19 of the fabric 20. When the guide means 23 through the warp thread surface 14 have been entered into the shed 15 form they are in the longitudinal direction A of the shed 15 extending guide for the gripper belt 1 and / or Guide part 24.
  • first guide element 25 on the gripper belt and / or the guide part 24 supports and a second guide element 26 that with the top of the gripper belt 1 and / or cooperates with the guide part 24 for the gripper 2.
  • the upper part 27 of the first guide element 25 supports the guide part 24. This upper part 27 points a rounded or conical shape.
  • In the area of Upper part 27 is also provided with a guide part 28, which is parallel to the gripper belt 1 and allows the gripper belt 1 between this guide member 28 and the Guide surface 29 of the second guide element 26 to guide.
  • the guide part 28 can - as shown - be flat or have a rounded or a cylindrical shape.
  • the guide surface 33 of the guide part 24 forms with the Gripper belt 1 an angle D and is guided by and supported over part of the length of the aforementioned top 27 of the first guide element 25.
  • the guide member 24 is not on the front End 34 of the upper part 27 of the first guide part 25 guided.
  • the second guide element 26 has an upper part 30 on that, like the top 27, a rounded or has a conical shape.
  • the guide member 24 is also laterally between one Guide surface 31 of the guide element 26 and a guide surface 32 of the guide element 25 out. Furthermore, the first guide element 25 has a surface 36 which is in the Area of the guide member 24 at a certain distance from the Lower surface 37 of the guide part 24 is located and as an emergency guide surface can act.
  • the upper part 30 is arranged in such a way that this upper part 30 almost parallel over a certain length to the warp thread surface 14 when the upper part 30 of the second guide element 26, the warp thread surface 14 straight touched and pass through the warp thread surface 14 to enter the shed 15.
  • the upper part 27 is arranged in such a way that this upper part 27 almost parallel over a certain length to the warp thread surface 14 when the upper part 27 of the first guide element 25, the warp thread surface 14 straight touched and pass through the warp thread surface 14 to enter the shed 15.
  • the arrangement of the upper parts 27 and 30 can Guide elements 25 and 26 favorably through the warp thread surface 14 pass through. For warp threads where different thin threads have been formed into a thicker thread are also avoided that the guide elements 25 and 26th can get caught between the individual threads that the Warp threads on one side of the guide elements 25 and 26 land or occasionally stay on it.
  • the length over which the upper part 27 is almost parallel to the warp thread surface 14 runs is preferably relatively large and greater than the length over which the upper part 30 runs parallel, because of the risk of breakage and / or damage of warp threads created by the upper part 27 is larger than that caused by the upper part 30.
  • This danger is greater because, on the one hand, the top part 27 is closer to the reed 9 than the upper part 30 and in so this top 27 less easily between the Warp thread surface 14 can penetrate, and on the other hand, because that Upper part 27 with the gripper belt 1 and / or with the guide part 24 works together and wear in such a way subject to.
  • rapier weaving machines it is known to have a rapier belt 1 an almost rectangular cross-section so central and / or to run as horizontally as possible through the shed 15.
  • the gripper belt 1 and the upper part 27, as mentioned above, at a certain angle D to arrange each other.
  • Guide part 24 has a projection under the gripper belt 1, which is provided with a guide surface 33, the one Forms an angle to the gripper belt 1 and with the upper part 27 of the Guide element 25 runs parallel.
  • the angle D is included so that the distance between the gripper belt 1 and the upper part 27 of the first guide element 25 in the direction of the front end 34 of the guide element 25 increases.
  • the upper part 30 of the guide element 26 an angle E with the gripper belt 1, which is a few degrees larger than the angle D that the Forms upper part 27 with the gripper belt. It is obvious that these angles D and E from the mutual position of the Shed 15, comb comb 8 and guide means 23 depend.
  • the individual guide means 23 in such a way can be arranged to each other that the first guide element 25 of first guide means 23 just under one second guide element 26 following guide means 23 arranged is.
  • the guide means 23, for example, has a shape as shown in FIGS. 3 and 4 with the guide elements 25 and 26 are spatially separated from each other. This allows with a single set of guide means 23, the first and second guide element 25 and 26 in the longitudinal direction A in one some distance from each other, as well first and second guide elements 25 and 26 in the longitudinal direction A to be provided at the same distance.
