Definitions

  • the invention relates to a sley for a weaving machine, in particular a pneumatic weaving machine, with a pivot shaft which is rotatably mounted in the machine frame and a reed beam which can be fastened thereon and is designed as a hollow beam and which contains a web part having a box-shaped cross-section and a head part provided with a longitudinal groove, which means is provided for attaching a reed insertable into the longitudinal groove.
  • the reed beam consisting of an extruded hollow profile is pivotally mounted in the machine frame with two shaft journals attached to its ends (CH-PS 630 671).
  • This design requires the reed beam to be rigid over the working width of the weaving machine, which at the same time contains compressed air supply channels for blowing nozzles distributed over its length and which therefore has a relatively complicated cross section.
  • the invention has for its object to provide, in a further development of the known design, a sley in a simplified design, which in particular the Formation of the reed beam carrying the reed and possibly other devices involved in fabric formation in a lightweight construction that is independent of the working width of the weaving machine.
  • the swivel shaft has a hollow shaft part which is designed to be substantially rigid over the working width of the weaving machine, and in that the hollow beam-like reed beam is designed as a non-self-supporting component over its length and two of the box-shaped cross-sectional part of the web part Contains on both sides protruding flange parts that can be placed on and connected to the hollow shaft part and extend essentially over the length of the web part.
  • the inventive design of the sley allows the use of thin-walled designs both of the load-bearing hollow shaft part and of the reed beam placed thereon and stressed over its overall length essentially without bending. Given the installation height of the axis of the swivel shaft, a correspondingly low overall height of the reed beam results due to the relatively large diameter of the rigid shaft part. Due to the relatively wide support of the reed beam, which can optionally be made flexible in terms of its overall length, on the rigid hollow shaft part, an operationally reliable connection of these dynamically highly stressed components and overall a high torsional rigidity of the structural unit thus formed is ensured.
  • a sley with a holding device for the reed attached to a hollow shaft is in itself out the CH-PS 572 117 known.
  • this known holding device does not contain a head part arranged on a web part at a distance from the hollow shaft.
  • the longitudinal groove receiving the reed is rather formed on a solid, and thus correspondingly relatively heavy, rail-like holding part which is fastened directly to the hollow shaft via lateral flanges.
  • This known arrangement would lead to a relatively heavy construction of the sley, particularly in the case of looms with a reed located at a greater distance from the hollow shaft.
  • the embodiment according to claim 2 enables an extremely thin-walled and light construction of the reed beam, which, due to the bending-free stress over the overall length, can essentially only be designed for a sufficient torsional rigidity of the beam profile under the operational stresses which occur in particular when the blade is stopped.
  • the embodiment according to claim 4 enables a substantially free arrangement of the facilities required for the storage and / or the drive of the sley over the entire working width of the weaving machine.
  • the head part of the reed beam can be designed according to claim 5 with an overall length that is independent of the length dimension of the web part, for example, or according to claim 6 with an overall length that is independent of the working width of the weaving machine.
  • the contact surfaces between the web part and the hollow shaft part can be kept small, on the one hand the processing effort for adapting the surfaces that can be placed on the hollow shaft part can be kept small and on the other hand the risk of fretting corrosion on the interacting surfaces can be counteracted.
  • the forces from the fastening of the reed beam over four staggered, essentially linear contact points in the circumferential direction of the hollow shaft part can be applied in a particularly gentle manner by the strip-like attachment parts of the flange parts which can be snugly placed on the lateral surface of the hollow shaft part be introduced into the hollow shaft part, so that deformation of the same can be avoided even with a thin-walled design of the hollow shaft part.

  • the shaft journal 10a is coupled via a coupling 19 to a shaft 9 mounted in the side part 3 of a drive device 4, not shown, which is known per se, for pivoting the sley 1.
  • the reed beam 6 has a head part 11 and a web part 12, which is provided with flange parts 13 which project laterally in the circumferential direction of the hollow shaft part 8 and can be placed thereon.
  • the flange portions 13 are fastened to the hollow shaft part 8 by screws 14.
  • the web part 12 is designed in the manner of a hollow profile beam with a box-shaped cross section, which is formed by two side walls 15 adjoining the head part 11 and two transverse walls 16 and 17 connecting them, and by a diagonal stiffening wall 18, which two Cavities 20 and 21 extending over the length of the web part 12 separate from one another.
  • the lower transverse wall 17, which connects the flange parts 13 to one another, is concave and runs at a distance A along the lateral surface of the hollow shaft part 8.
  • the surfaces of the flange parts 13 facing the hollow shaft part 8 are each provided with a groove-like recess 22, which lies between two the lateral surface of the hollow shaft part 8 can be put on, and the strip-like attachment parts 23 and 24 extending over its longitudinal extent are formed.
  • the Depth of the depressions 22 correspond to the distance A.
  • the upper transverse wall 16 separates a cavity 25 which extends through the head part 12 over its length from the cavity 20 of the web part 12.
  • the head part 12 is provided with a longitudinal groove 26 which extends over its length and is designed to receive a foot part 27 of the reed 7 and a clamping piece 28 which can be placed on the foot part 27 or a plurality of corresponding clamping pieces 28 which are arranged distributed over the length of the longitudinal groove.
