Definitions

  • the invention relates to an uncontrolled tensioning unit of a weaving machine for a weaving chain consisting of tear-sensitive warp threads.
  • a weaving machine with a smooth-running tensioning device for the warp is known from EP application 0 396 501.
  • the task of the tensioning device here is to create a smoothly driven tensioning system for a warp that is also suitable for heavy fabrics and is sensitive to tension fluctuations in the warp or changes in position in the drive of the system.
  • the object is achieved in that an adjusting mechanism, consisting of a length-adjustable push rod, which is connected to a drive derived from the main drive of the loom and the adjusting mechanism acts on a spring connected to a drive shaft, which is designed as a torsion bar.
  • the drive shaft which is operatively connected to the torsion bar, carries a rotationally symmetrical coating or tensioning roller in bearing points distributed over the weaving width.
  • a device for tensioning the warp which also consists of a torsion spring rod connected to a drive, which is arranged in a hollow shaft designed as a hollow shaft and supporting the coating roller or tension roller.
  • the object of the invention is to provide an uncontrolled tensioning unit for tear-sensitive warp threads of a warp, with which the warp can be tensioned in a simple manner, in which the coating and deflecting roller is designed with low mass, on a conventional support beam on which the coating roller supports, dispenses, in which the coating and the deflection roller is loosely carried, which can be positioned in terms of weaving conditions in the vertical and horizontal plane and which enables a torque compensation in the tensioning unit with possibly different loading of the coating roller.
  • the clamping unit 1 consists, among other things, of a cross member 2 which is firmly connected to a first left and a first right component 3.
  • the components 3 are slidably carried in a further left and a further right component 4.
  • the component 4 is pivotally connected to the respective side wall 5 and can be locked on the side wall 5 by connecting elements (not shown) via the elongated holes 5a and, for example, threaded holes not visible here.
  • Each component 4 forms a longitudinal groove 4a and elongated holes 4b for connection to the respective component 3, by means of which and by means of connecting elements, not shown, the component 3 on the component 4 at a desired distance can be positioned to the technical and tissue imaging organs, not shown.
  • the individual end shields 6 receive at their free end a lever 8 arranged pivotably about an axis of rotation 7 and parallel to it a lever 9 arranged in a rotationally fixed manner. Both levers form a roller bearing 8a, 9a.
  • the roller roller 10 is loosely carried in the roller bearing 8a of the pivotably arranged lever 8 and the deflection roller 11 is loosely carried in the roller bearing 9a of the non-rotatable lever 9.
  • All bearing plates 6 are penetrated transversely in the area of their connection to the cross member 2 by a shaft 12 adjustable about their longitudinal axis 12a or the shaft 12 is received in corresponding bearings and e.g. connectable with at least one of the end shields 6 in a locking manner.
  • the tensioning unit 1 also has a torque compensation in order to rule out any asymmetrical loading on the warp 15.
  • a roller bearing carrying a roll neck 10a is inserted into the two free ends of the coating roller 10.
  • a roller bearing 17 is also integrated, which rotatably receives a so-called stabilizer shaft 18, which passes through the deflection roller without contact, on its shaft journal 18a.
  • a tab 19 establishes an operative connection between the rotatably mounted stabilizer shaft 18 and the respective roll neck 10a.
  • connection between the roll neck 10a and the tab 19 is carried out in such a way that the tab 19 has a longitudinal guide 19a into which the roll neck 10a, which has corresponding guide surfaces 10b, engages.
  • a positive connection for example a screw connection 20, between the respective shaft journal 18a and the tab 19.
