Definitions

  • the invention relates to a needle ribbon loom with a shaft device forming a shed according to the preamble of claim 1.
  • Needle ribbon looms of the type mentioned at the outset with a shaft device forming a shed are known several times.
  • the shaft device has shaft frames.
  • the problem with the latter is that they are no longer sufficiently stable at larger dimensions and / or at higher speeds of the needle ribbon weaving machine.
  • the shaft rails tend to bend and sufficient force transmission between the shaft rails is no longer guaranteed. This can lead to the destruction of the socket frame.
  • the object of the invention is to improve a needle ribbon loom of the type mentioned.
  • the shaft frame has at least one shaft support, which has a hollow rod with an upper lateral entry opening for an upper shaft rail and a lower lateral entry opening for a lower shaft rail, such a shaft support can be retrofitted at any point on the shaft frame for reinforcement.
  • the upright shaft rails are connected via a pressure rod arranged in the hollow rod and are braced against one another by means of a tension screw arranged on one end part of the hollow rod and coaxial to the pressure rod. This results in a substantial stiffening of a
  • Shaft frame so that it is suitable for larger dimensions on the one hand and / or higher speed on the other hand.
  • stock supports can also be used for the basic structure of the stock frame, the This means that shaft supports can also be used on the sides to connect the upper and lower shaft rails.
  • the hold of the shaft rails can be improved if, according to claim 2, at least one entry opening has a lateral support flange pointing in the direction of the hollow rod.
  • the hollow rod can be made of solid material.
  • the embodiment according to claim 3 is more advantageous, according to which the hollow rod has recesses distributed over its length on opposite sides and offset with respect to one another, which results in a substantial reduction in the moving mass.
