Definitions

  • the invention relates to a reed for a weaving machine with a plurality of profiled slats arranged next to one another, which form a guide channel for a transport medium and weft threads, and a weaving machine with such a reed.
  • Air jet looms typically use a reed made of U-shaped lamellas, which together form a guide channel in which a weft thread is transported by means of a compressed air stream.
  • the reed is attached to a shop beam.
  • a plurality of auxiliary nozzles or relay nozzles, which blow an air stream into the guide channel by means of at least one outlet opening, are arranged on the loading beam next to the guide channel over the length of the reed. This air flow transports a weft thread introduced into the guide channel by means of a main nozzle further in the longitudinal direction of the guide channel.
  • Provisions can further be made in accordance with this document to support the escape of compressed air between the lamellae predominantly on the upper side of the U-shaped guide channel, in particular in the uppermost section of the base area and at the rearmost section of the upper side of the guide channel. With such a reed, it is possible to influence the transport air flow in the guide channel and to make the reed sufficiently rigid so that the risk of warp strips being formed is relatively low.
  • the reed Because of the chamfer, less transport air flows between the lamellae to the rear of the reed, ie the reed has a lower permeability for the transport medium to the back of the reed, compared to a reed made of lamellae with straight, not chamfered boundary edges. Such a reed is called a reed with a strong air flow. If, however, an excessive air flow occurs in the guide channel with such a reed, it can be determined that weft threads leave the guide channel on the open front side, which in most cases causes a weaving error.
  • the invention has for its object to design a reed of the type mentioned in such a way that the air flow can be positively influenced, but the risk is low that a weft thread leaves the guide channel on the open front.
  • the guide channel has successively sections with greater and lesser permeability for transport medium flowing out of the guide channel between the lamellae at least over part of its length by means of the design and / or arrangement of the lamellae.
  • the distance between the auxiliary nozzles or groups of auxiliary nozzles that cooperate with the reed can be selected such that the distance between the auxiliary nozzles or groups of auxiliary nozzles is essentially equal to the length of a section with less permeability and a section with larger ones Is permeability.
  • the one emerging from the auxiliary nozzles Air flow can be guided differently by means of the sections of different permeability, so that a strong air flow is obtained in the guide channel without the risk that a weft thread leaves the guide channel on its open front side.
  • the fins in the section to which the air flow is directed have a different permeability than the fins to which no air flow exiting from the auxiliary nozzles is directed and which essentially serve to direct the air flow in the guide duct further to the following fins to which an air flow is directed from the next auxiliary nozzle.
  • the amount of air that escapes between the lamellae of the reed fluctuates relatively little in the longitudinal direction of the reed, which leads to a largely uniform air flow in the guide channel.
  • a weft thread is transported through the guide channel under improved conditions.
  • the auxiliary nozzles only introduce an air stream into the guide channel at some points and although the lamellae of the reed have essentially the same profile and form a guide channel with an essentially constant flow cross section, the transport of the weft threads can be improved.
  • the Air flow in the guide channel of the reed according to the invention can be selected to be relatively strong in order to transport a weft thread.
  • the reed has essentially only lamellae in one section which cause a relatively high permeability with regard to the escape of compressed air to the rear of the reed, and in another section essentially only lamellae which have a relatively low permeability with respect to the Cause compressed air to escape to the rear of the reed.
  • the length of two successive sections with different permeability is, for example, between 20 and 120 mm.
  • the length of the sections is preferably substantially the same as one another.
  • different types of lamellae are arranged next to one another in periodically repeating sections after a certain distance from one side of the reed up to a certain distance from the opposite side of the reed.
  • the slats, which are arranged on one side of the reed, do not have to be different from one another and arranged according to a pattern.
  • the length of each section is the same. This can be achieved by arranging the auxiliary nozzles or groups of auxiliary nozzles at the same distance from one another as is the case with most air jet weaving machines. In other embodiments, the length of the sections is different, which is provided in particular when the distances between the auxiliary nozzles or groups of auxiliary nozzles are not the same.
  • the transition between the sections is different in terms of permeability the abrupt escape of transport medium between the slats.
  • each section contains only lamellae which cause a relatively high permeability or only lamellae which cause a relatively low permeability.
  • the transition between the areas of different permeability is designed to be fluid.
  • each section essentially contains only lamellae which cause high permeability or only lamellae which cause low permeability, while in the region of the transition between the two sections according to a predeterminable pattern both lamellae which cause high permeability also slats are arranged which cause low permeability.
  • the different slats with a U-shaped profile form a guide channel, the geometric shape of the slats being essentially the same with respect to the U-shaped profile.
  • the reed contains at least two different types of slats, with at least the boundary edges of the slats, which form the base of the U-shaped guide channel, being at different angles to the longitudinal direction of the guide channel.
  • Such a reed with lamellae in which the base surface - or also the stop surface - of the guide channel of differently inclined directional boundary edges of the recesses of the slats is formed, has no significant influence on the impact effect when a weft thread is struck.

  • the reed 2 is positioned in relation to the auxiliary nozzles 10 as a function of the areas 17 of the reed 2.
  • This displacement P is caused by the fact that it is not the position of the auxiliary nozzles 10 themselves that is important for the selected permeability of the reed 2, but rather the point where the air flow reaches the reed, which is blown out of the auxiliary nozzles 10.
  • the displacement P is chosen, for example, so that the reed 2 has a lower permeability at the points where the air flow reaches the base of the guide channel 13 of the reed 2 and a higher permeability at the other points. In this way, a weft thread 14 can be held in the guide channel 13 by the air streams of the auxiliary nozzles 10 directed towards the reed 2.
  • the weft thread is held in the guide channel 13 in that the compressed air escapes between the lamellae of the reed to the rear of the reed 2.

This is useful since the oblique boundary edges of the profiling of the slats 3 and 4 are difficult to see with the naked eye. Of course, it is also sufficient if only one of the types of slats is marked, i.e. the slats 3 or the slats 4.
  • the arrangement of the different lamellae 3 and 4 has been carried out differently from the embodiment according to FIG. 4.
  • This arrangement ensures that the transition between the sections 19 and 20 of different permeability with regard to the escape of compressed air between the lamellae 3, 4 of the reed 2 is not sudden, but more gentle.
  • lamellae 3 of one type and lamellae 4 of the other type are alternately arranged in the area of the transition in sections 19 and / or 20.

  • the reed has 2 lamellae 24 and 25.
  • the flow resistance between the fins 25 is thus lower in this area, so that there is a greater permeability between the fins 25 than between the fins 24.

  • not only the rear boundary edge 18 but also the boundary edges of the upper projection 16 and the lower projection 16A are inclined.
  • the bevels of the fins 3 are opposite to the bevels of the fins 4. Since the air flow of the auxiliary nozzles 10 is directed obliquely upwards, only a little compressed air will escape in the area of the underside of the guide channel 13 between the fins.
