  • This concept is essentially based on a fixed blowing pressure, namely 2.5 bar or 5 bar, which can still be varied in the control system. It has been found, however, that pressure regulation according to this concept is on the one hand very complex and on the other hand - at least with an acceptable outlay - only low pressure control bandwidth can be achieved.
  • the object of the invention is to provide an improved jet loom, which overcomes the disadvantages of the prior art described above.
  • sub-switching elements are particularly advantageous for a small number of sub-switching elements - as defined in claim 4 - when the sub-switching elements each provide a different Blasmassenstrom available.
  • the sub-switching elements advantageously have a valve, preferably a 2-2 valve.

  • either different valves or differently set valves can be used.
  • an additional throttle means is arranged.
  • the determination of the control of the sub-switching elements is then advantageously carried out according to claim 7 by a control or regulating device with a switching logic table means and / or a calculation means for automatic control. If a control is provided, it is advantageous if means for comparing the firing time and / or the angle of arrival are used, wherein the control or regulating device is arranged so that the firing time control can be performed by an optional switching on or off of sub-switching elements.

Abstract

Afin de pouvoir commander rapidement et simplement, dans un métier à tisser à tuyères, la quantité d'air sortant au niveau des tuyères principales (12, 13, 14, 20), dans lesquelles les fils de trame sont acheminés et accélérés au moyen d'un milieu de soufflage, mais toutefois aussi au niveau de tuyères auxiliaires et de tuyères d'étirage (21, 22, 23, 30; 31, 32), l'élément de commutation principal (H<SUB>1</SUB>-H<SUB>n</SUB>) présente selon l'invention une pluralité d'éléments de commutation partiels commutables de manière sélective (T<SUB>1</SUB> à T<SUB>9</SUB>), qui disposent chacun de leur propre flux massique de soufflage. Le flux massique de soufflage peut être ajusté de manière échelonnée par addition réglable des éléments de commutation partiels (T<SUB>1</SUB> ... T<SUB>9</SUB>).
