Definitions

  • the invention relates to a weaving machine comprising a mechanism for the reverse run of a reed composed of a multimember mechanism with a lowered reduced moment of inertia and coupled with a drive consisting of a motor coupled with a control device, wherein the reed is positioned on a stringer of a batten wherein the stringer of the batten is an inner member of the multimember mechanism and a crank and walls of the batten represent outer members of the multimember mechanism.
  • a weaving machine whose principle is in that said motor is a motor with controllably variable spin velocity within each revolution.
  • the invention is schematically shown on the picture describing side cut of weaving machine arrangement for a leno fabric weaving machine.
  • a driving device imparts a reverse movement to the stringer and consequently to the reed by the action of external deflection force.
  • the reverse movement of the stringer and all parts fixed on it, in particular the reed is realized between their beat up and shed positions.
  • Due to deformation of the leaf springs the stringer with the reed displays curvilinear translation motion. Nevertheless the leaf springs can be found in an upright balanced position or in a deflected position or a position deflected towards the other side.
  • the leaf springs from each of deflected positions tend to return to their balanced position, where they are upright. That means that the entire batten tends to return to its balanced position and doing so it subsequently tends to hold it.
  • In the batten deflected position is an energy accumulated in the leaf springs, which generates restoring force acting while their reverse movement back to the balanced position.
  • the batten is composed of a body formed of deformable walls connected by a connecting wall, representing the stringer of the batten, into an open rectangular section.
  • a connecting wall representing the stringer of the batten
  • Deformable walls of the batten are composed of the leaf springs, whose ends are firmly fixed on the beam, which is settled on the frame of the weaving machine.
  • the batten composed of one piece of a shaped composite material, which is made of a fibrous reinforcing material in a polymer matrix.
  • the fibrous reinforcing material can advantageously be made of a system of carbon fibers or directed layers of separate carbon fibers.
  • the polymer matrix is advantageously composed of an epoxy resin.
  • the leaf springs due to their pivoted fixing in hinges of the machine frame bend only into one arch. They are however able to take a deflected and the balanced position, while they can be deflected into any side of the batten. In the batten deflected position is an energy accumulated in the leaf springs, which generates restoring force acting while their reverse movement back to the balanced position.
