  • the mounting bar is arranged above the fabric area.
  • the fabric area is defined as an area of a woven fabric and of warp threads neighboring a beat-up line, wherein a section of the fabric, which section extends between the warp threads and a fabric take-up system, and a section of the warp threads, which section extends from the beat-up line, are arranged in the fabric area.
  • the mounting bar is arranged above the fabric area and in a height direction higher than the fabric take-up system.
  • Known mounting bars have a rectangular cross-section.
  • the weaving machine devices are attached to the mounting bar using rectangular sleeves that are fitted onto the mounting bar and secured to the mounting bar at a desired width position of the frame.
  • a frame for a weaving machine comprising a mounting bar arranged above a fabric area, wherein the mounting bar is configured so that weaving machine devices can be fixed thereto, and wherein the mounting bar is a longitudinal profile having a longitudinal groove at its periphery.
  • the indefinite article “a” or “an” means “one or more”.
  • the longitudinal profile in embodiments is provided with more than one longitudinal groove.
  • the expressions “first” and “second” are only used to distinguish one element from another element and not to indicate any order of the elements.
  • the mounting bar forms part of the frame for the weaving machine.
  • the frame in embodiments further comprises two side parts and a cross beam connecting the two side parts to each other.
  • the mounting bar in the form of a longitudinal profile having a longitudinal groove allows a fixation element to engage the longitudinal profile for fixing a weaving machine device to the longitudinal profile without the necessity that the fixation element surrounds the mounting bar.
  • the longitudinal profile is provided on at least two sides with a longitudinal groove.
  • the two longitudinal grooves allow that a fixation element for attaching the longitudinal profile to a side part of the frame and/or for fixing a weaving machine device to the longitudinal profile can clamp the longitudinal profile with a form fit.
  • a need for an additional machining of the longitudinal profile for providing through holes or similar elements in order to attach the longitudinal profile to the side part and/or in order to fix a weaving machine device to the longitudinal profile can be dispensed with.
  • the fixation element in an embodiment is an arc-shaped or U-shaped bracket having inwardly pointed tips engaging the longitudinal grooves.

  • the frame comprises a first side part and a second side part, wherein the longitudinal profile is attached to the first side part via a first support and/or attached to the second side part via a second support.
  • the frame comprises a first side part and a second side part and comprises two longitudinal profiles, wherein a first longitudinal profile is attached to the first side part via a first support and a second longitudinal profile is attached to the second side part via a second support.
  • a frame is in particular suitable for use with a jacquard weaving machine, wherein the two shorter longitudinal profiles do not block or at least essentially do no block a visibility of harness wires of the jacquard weaving machine.
  • Such a frame is also suitable for use with a weaving machine, wherein another device is arranged above the fabric area between the first side part and the second side part, for example a jacquarette.
