Definitions

  • the invention relates to a device for the guidance of leno threads for a leno weaving machine, with a multiplicity of guide eyes which each receive a leno thread and which are arranged next to one another in at least one row running in the direction of the weaving width.
  • Devices of the type mentioned in the introduction cooperate with needles which receive warp threads in guide eyes.
  • the device having the guide eyes for the leno threads is moved such that the leno threads are brought alternately onto one side or the other of the warp needles, in each case a shed being formed into which a weft thread is inserted.
  • the warp needles are designed, in the type of construction according to EP 1 277 862 A1 , as lamellae which are provided with guide eyes at their ends. Guide lamellae are arranged between the lamellae.
  • the device for guiding the leno threads is conventionally a perforated strip which is arranged in a profile rail.
  • the object of the invention is to provide a device of the type mentioned above, which allows to arrange the guide eyes closely next to one another, so that a dense leno fabric can be produced.
  • the guide eyes are formed by means of lamellae and two rods and are delimited in the direction of the weaving width by means of the lamellae and transversely thereto by means of the two rods.
  • the device being formed according to the invention from lamellae and rods, it is possible to provide guide eyes which lie very closely next to one another and are separated from one another only by the thickness of the lamellae.
  • the lamellae together with the rods and two lamella-like side parts form a frame. In this case, it is expedient if the ends of the preferably cylindrical rods are fixed in the side parts.
  • the device can be produced in a similar way to that known for reeds or the like.
  • the spacing of the lamellae with respect to one another is fixed by means of a coiled spring or a binding wire.
  • the coiled spring or the binding wire, after assembly, may remain in the device or else be removed from it.
  • the lamellae there is provision for the lamellae to be fixed at a predetermined spacing with respect to one another by means of at least one strip extending in the direction of the weaving width.
  • a connection between the strips and lamellae to take place by means of an elastic and/or plastic deformation of, in particular, the strips, so that the article formed in this way can immediately be handled and transported.
  • the lamellae in a further embodiment of the invention, there is provision for the lamellae to be bordered in the region of one end by a fastening profile. This likewise corresponds to the production of a reed or the like, in which the lamellae used for the reed are likewise held by means of a fastening profile.
  • the lamellae in a further embodiment, there is provision for the lamellae to be bordered at both ends by profiles.
  • the device can thus be formed into a frame which surrounds the lamellae.
  • Fig. 1 shows a perspective part view of a device according to the invention
  • Fig. 2 shows the part view of the device according to Fig. 1 in a kind of exploded illustration
  • FIG. 3 shows the front view of the device according to Fig. 1 .
  • FIG. 4 shows the end view of a modified embodiment
  • Fig. 5 shows a further device for holding the lamellae
  • Fig. 6 shows a perforated. strip for leno warp threads of a weaving machine
  • Fig. 7 shows a variant of an arrangement for holding the lamellae.
  • the device according to Fig. 1 to 3 comprises a multiplicity of lamellae 10 which are arranged in a row one behind the other in such a way that their flat sides face one another.
  • the lamellae 10, which are arranged at a close spacing with respect to one another, are provided with perforations, through which two round rods 11 and 12 are inserted.
  • the rods 11 and 12 are, for example, of cylindrical design.
  • the lamellae 10 and the rods 11 , 12 form guide eyes 21 for leno threads. These guide eyes 21 are in each case delimited in the direction of the weaving width by two lamellae 10 and transversely thereto by the two rods 11 , 12.
  • the lamellae 10, in the region facing away from the rods 11 , 12, are provided in their narrow sides or side edges with recesses, into which are pressed strips 14, 15 which connect the lamellae 10 to one another.
  • the strips 14, 15 are preferably attached on both narrow sides of the lamellae 10 and are pressed under elastic and/or plastic deformation into the recesses 13 of the Ia- mellae 10 in such a way that they are deformed elastically and/or plastically and at the same time form an at least positive connection with the lamellae 10.
  • the lamellae 10 are arranged in the desired spacing in a device, so that the recesses 13 are in alignment with one another.
  • lamella-like side parts 16 are provided, which correspond in shape to the lamellae 10 and which are provided with means 17 for fixing the rods 11 , 12. These may, for example, be sockets into which the rods 11 , 12 are fitted.
  • the strips 14, 15 also extend as far as the side parts 16, so that these likewise form with the lamellae 10 and the rods 11, 12 a structural unit which as such can be transported and handled.
  • the structural unit comprising the lamellae 10, the round rods 11 , 12, the strips 14, 15 and the side parts 16 is inserted into a fastening profile 18.
  • the fastening profile 18 is preferably an extruded profile.
  • the structural unit is inserted, with the region in which the strips 14, 15 are located, into a groove-shaped recess of the profile 18. They are fixed in this re- cess in a known way by means of a curing plastic material.
  • the lamellae and the rods may also be connected to one another in any way, in particular according to methods which are employed for the production of reeds.
  • helically coiled springs or windable binding wires may be used in order, during the production of the device, to define exactly the spacing of the lamellae 10 with respect to one another.
  • the lamellae 10 are provided, outside the region between the perforations, with profilings which define the mutual spacing of the lamellae, so that, during the production of the device, these lamellae 10 can be plugged onto the rods 11 , 12 and lined up with one another.
  • the device illustrated in Fig. 4 which comprises lamellae 10' and rods 11', 12', is produced by a modified production method.
  • the mutual spacing of the lamellae is defined by means of a helically coiled spring 19.
  • the regions, facing away from the rods 11', 12', of the lamellae 10' which may be connected to one another by means of strips correspondingly to the exemplary embodiment according to Fig. 1 and 2, are inserted into a fastening profile and held together with the latter by means of a curable plastic.
  • the mutually opposite ends of the lamellae 10' are likewise connected to one another by means of a supporting profile 20.
  • the two profiles 18, 20 are connected to one another by means of side parts in a way not illustrated in any more detail, so that a rigid frame is formed.
  • Guides 27' for holding the narrow sides of lamellae 10 are illustrated by way of example in Fig. 5.
  • the lamellae 10 are provided on their mutually opposite narrow sides with recesses 13 into which strips 14, 15 are pressed.
  • the relatively short lamellae 10 run out slightly obliquely in the region facing away from the recesses 13, so that the said lamellae taper.
  • the guide elements 27' hold the lamellae 10 in this re- gion.
  • the lamellae 10 are provided in each case with two holes 31 , 32. Round rods or round tubes are inserted into these holes 31 , 32 of the lamellae 10. The leno threads are then guided between the rods and adjacent lamellae 10, when this device is used as a replacement for a perforated strip, as will be explained later with reference to Fig. 6.
  • the lamellae of the embodiment according to Fig. 6 differ from the lamellae of the embodiment according to Fig. 5 in that they do not have a coni- cal configuration in the region of the rods. However, they are connected to one another in the same way by means of strips 14, 15 pressed into recesses 13.
  • the device formed from a multiplicity of lamellae 10 and the rods 11 , 12 is inserted into a profile 18 and is held in the latter by means of a curing plastic. This profile 18 is attached to an associated component of a leno weaving ma- chine.
  • Fig. 7 shows an arrangement for holding lamellae 10 which is similar to Fig. 5.
  • holes 31 , 32 for inserting round rods or round tubes, not illustrated, and recesses 13 for strips 14, 15 are arranged on opposite sides of a guide element 27'.
  • the lamellae 10 taper in the direction of the recesses 13, so that the side edges have a slightly oblique design at least in one region.
  • the guide elements 27' hold the lamellae 10 in this region.
