Definitions

  • the invention relates to a weft feeder nozzle for weaving machines, in particular rapier projectile weaving machines, in weft change operation, with a housing and a number of nozzle inserts arranged therein, each carrying a weft thread.
  • a known device of this type (US Pat. No. 3,750,716, FIG. 12) has the disadvantage that the nozzle inserts are arranged parallel to the direction of insertion, which necessitates an adjustment of the position between the entry element and the nozzle insert which guides the weft thread to be inserted.
  • the invention is based on the object of creating a weft dispenser nozzle of the type defined in the introduction, the exit surface of which for the weft threads is small and is aligned with the center of the gripper projectile.
  • This object is achieved according to the invention by the features specified in the characterizing part of claim 1.
  • the subclaims relate to advantageous developments.
  • the weft dispenser nozzle 1 consists of a housing 2 with three nozzle inserts 3, 4 and 5 arranged therein, each of which carries a weft thread 6, 7 and 8 in a bore 9, 10 and 11.
  • the housing 2 and the nozzle inserts 3, 4 and 5 converge in the entry direction, ie in the direction of a gripper projectile, of which only the thread clip 12 is drawn.
  • the housing 2 is provided with a guide sleeve 13 for the weft threads, which tapers in the entry direction, such that the donor nozzle 1 as a whole is aligned with the center of the thread clamp 12.
  • the end 13 'of the guide sleeve is cylindrical, so that the weft thread to be transferred enters the thread clamp 12 in the axial direction.
  • the guide sleeve 13 is made of a transparent material, which facilitates the adjustment of the weft ends.
  • the guide sleeve 13 is detachable, for example by means of a screw connection 14, attached to the housing so that it can be replaced. This makes it easier to adapt the position of the sensor nozzle to the different machine types and sizes and also to clean the housing of flight and dust.
  • the screw connection 14 can also be used to make small corrections at a distance from the mouth 15 of the transmitter nozzle to the gripper projectile.
  • Compressed air is supplied through a feed line 16, which cavity 17 flows between the nozzle inserts 3, 4 and 5 and the housing 2 and exits through the guide sleeve 13.
  • a feed line 16 which cavity 17 flows between the nozzle inserts 3, 4 and 5 and the housing 2 and exits through the guide sleeve 13.
  • a partition between two nozzle inserts In the mouth area of the nozzle inserts 3, 4 and 5 there is a partition between two nozzle inserts.
  • the air flowing through the housing 2 causes a negative pressure in the mouth region of the nozzle inserts 3, 4 and 5, which creates a suction effect in the bores 9, 10 and 11 and flows outside air through the bores.
  • the tensile force of the incoming outside air keeps the weft threads taut in the holes.
  • Each weft thread is held taut by a thread tensioner (not shown).
  • a thread brake (also not shown) is provided for each weft thread.
  • a second weft thread is released in the manner described by the associated thread tensioner and transferred from the nozzle to the projectile at the same time, so that both weft threads are inserted by the projectile.
