Definitions

  • the present invention concerns an improved automatic needle loom of the kind where the warp thread shed formation is controlled by a Jacquard system.
  • the present invention is directed to a needle loom for the manufacture of narrow fabrics wherein the operating synchronism between weaving loom and jacquard system is accomplished by means of separate motors.
  • Weaving looms are known in which the shed formation is controlled by a jacquard system.
  • the movement is driven by the weaving loom main shaft that, through appropriated gear connections transmits the movement to Jacquard system allowing shed formation with a required synchronism.
  • US - A - 5,613,526 discloses a system consisting of a series of independent motors controlling shaft movement. Said motors may be of the kind of brushless motors.
  • It is an object of the present invention a device for textile product manufacture comprising a jacquard system for warp thread shed formation in which jacquard operation is driven by a motor independent on the motor which drives the weaving loom movement.
  • the apparatus which comprises a jacquard system for warp thread shed formation wherein the synchronism between jacquard and weaving loom is assured by two separate motors, the motor controlling jacquard movement being a direct current supplied synchronous motor, e.g. a brushless motor.
  • the synchronism between the jacquard and weaving loom is assured by two synchronous motors loom supplied by direct current of the kind of brushless motors or equivalent which allows, in a easy way, the weaving loom shaft movement programming as well as a very precisely definition of the rotation speed ratio of the driving shafts.
  • the latter embodiment assures a good operation without any overheating, even in the low running phase (about 60 rpm) of the weaving driving motor, therefore eliminates the necessity of an auxiliary geared motor and reduces the overall cost and size of the apparatus.
  • the use of direct current supplied synchronous motor as the brushless motor or an equivalent one enables, contrary to three-phase motors to prefix the operating speed with a very high precision.
  • the ratio of revolution number of the weaving loom shaft and the revolution number of jacquard is generally two: i.e. for each revolution of jacquard shaft, the weaving loom shaft makes two revolutions.
  • such a ratio is obtained by mechanical connection by using gear wheels connected by means of belts or chains or it has been suggested to use two different conventional motors (asynchronous, three-phase motors) driven on electrical axis and controlled by appropriate inverters.
  • Such embodiment has the inconvenient of a reduced efficiency at low running and an imperfect synchronism.
  • the device according to this invention is advantageously applicable to needle weaving looms for the manufacture of narrow ribbons, preferably the needle weaving looms for the label production.
  • 7 is the jacquard system supporting plate as well as its brushless motor. Plated 7 can be lowered down as it is illustrated in fig. 3 showing the jacquard-waving loom complex in a ready for shipping phase. The lowered jacquard-waving loom complex can be shipped using standard size containers.
  • Fig. 2 is a diagram reporting on the axis of abscissa the angles relevant to the rotation of the jacquard and weaving loom driving motor shafts. As ordinates the shafts rotation speed in revolutions per minute is reported.
  • the jacquard driving motor shaft rotates at an average speed that is one half of the speed of the weaving loom driving motor shaft.
  • the rotation speed of the weaving loom driving motor shaft is always constant, the rotation speed of the jacquard driving motor shaft change within each single revolution angle.
  • the rotation speed of the weaving loom driving motor shaft is shown as a straight line parallel to axis of abscissae (A)
  • the speed of jacquard driving motor shaft is shown as a sinusoidal line (C) since said speed is higher in the ranges 0° to 90° and 180° to 270°, but is lower in the in the ranges 90° to 180° and 270 to 360°.
