  • Patent number: 4153226
    Abstract: A supporting mechanism particularly adapted for supporting weaving machines on a base by means of which the machine frame of the weaving machine is suspended by cables which are adjustably secured on four support levers. Four support brackets are disposed at the four corners of the machine frame and rest on the ground or a base. Each bracket is provided with a bearing and each lever is provided with a fulcrum. Two torque rods are provided, one on each side of the machine frame. Each torque rod is rigidly secured to one lever and to an oppositely disposed bracket. By virtue of the coaction of the suspension support of the machine frame by four cables, the pivot support supplied by coacting bearings and fulcrums and the action of the torque rods the weaving machine is cushioningly supported by the support mechanism.

  • Patent number: 4085777
    Abstract: A novel construction of a control plate inserted within and corresponding to a system of plates of a picking comb of a fluid-jet loom is described. The exit opening of the control plate has a detecting section including a light source and a photocell disposed in aligned spaced relation on opposite sides of the exit slot. The width of the exit slot is narrowed, at the location of the source and photocell, to a dimension substantially equal to the diameter of the weft thread exiting from the picking space of the control plate. At least one of the light source and photocell projects into the narrow exit slot to assure an enhanced wiping action of the weft thread on the detecting elements as the weft thread moves through the exit slot.
