Definitions

  • the invention relates to a rapier weaving machine with guide means which are attached to a sley and can be inserted through a warp thread sheet into a shed for forming a guide for a rapier in the direction of the shed.
  • guide means are provided which can cooperate with one or with both side surfaces and / or with the upper side of the rapier belt.
  • guide means are provided which can work together with the underside, with one or both side surfaces and / or with the top side of the rapier belt. Examples in this regard are described in US 3299911 and in EP-A 406926.
  • These guide means is chosen so that on the one hand they ensure good guidance for the looper belt, but on the other hand give no cause for damage and / or breakage of the threads. Special forms of guide means are therefore required when weaving fabrics with specific weaves.
  • a suitable shape of the guide means can be selected for each type of fabric to be woven.
  • the shape of the guide means can also be selected as a function of the point at which the gripper belt is to be guided in the shed.
  • the invention has for its object to simplify a change in the guide for the gripper belt.
  • the guide means are each equipped with at least two differently designed guide elements, and in that the individual guide elements can optionally be used to form a guide by changing the attachment position of the guide means on the sley.
  • the invention offers the advantage that individual guide elements can be selected in a simple manner from the existing guide elements, wherein different guides for the gripper belt can be created by optionally attaching the guide means to the sley, which guides are adapted to the type of fabric to be produced.
  • Fig. 1 the sley (1) of a weaving machine is shown, which for example consists of a driven weaving axis (2), attached saddle legs (3) and an attached, corresponding to the width of the weaving machine (4) with a reed (5 ) and tensioning devices (6) for the reed (5) (or reed). Furthermore, a gripper belt (7) with a gripper (8) mounted thereon, the warp threads (9) and the fabric (10) are shown schematically.
  • the weaving machine has a guide (11) for the rapier belt (7), which is formed from guide means (18, 18 '), which have guide elements (12, 13, 14, 15) and on the sley profile (4) the sley are attached.
  • a second profile (16) which corresponds to the width of the weaving machine, is fastened to the weaving profile (4) at a desired height, for example with screws (17).
  • the guide means (18, 18 ') and the guide elements (12, 13 and 14, 15) are made in one piece and are each attached to the sley (1) in such a way that one of the guide elements (12 or 13 and 14 or 15 ) cooperates with the gripper belt (7).
  • the guide means (18, 18 ') are fastened to the second profile (16) with screw means (19).
  • screw means (19) there is a bore in the guide means (18), which contains the guide elements (12 and 13), a bore or a slot in the second profile (16) into which the screw means (19) can be inserted, and in the guide means (18) , which contains the guide elements (14 and 15), a thread is provided which cooperates with the screw means (19) in order to thread the guide means (18) with the guide elements (12 and 13) and the guide means (18 ') with the guide elements (14 and 15) to be attached to the profile (16).
  • the screw means (19) are arranged in such a way that they are easily accessible for loosening or tightening, without the need to remove the reed (5) and / or the profile (16).
  • the screw heads are arranged on the side facing away from the reed (5).
  • Lugs (20) are provided on the guide means (18, 18 '), which engage in a recess (21) in the second profile (16) running transversely to the weaving machine in order to enable their precise positioning.
  • the guide means (18, 18 ') are attached to the sley in such a way that either one of the guide elements (12 or 13 and 14 or 15) cooperates with the rapier belt (7). In the position shown in FIGS. 1 and 2, the guide elements (12 and 14) work together with the gripper belt (7), while the guide elements (13 and 15) are not used.
  • the screw means (19) do not have to be completely loosened, but can only be loosened in such a way that the lugs (20) of the guide means (18, 18 ') in question permit such a rotation.
  • the screw means (19) can then be tightened again. This makes it possible to move the desired guide element (12 or 13) and / or (14 or 15) relatively quickly into a position in which it can work with the gripper belt (7).
  • FIG. 8 A further embodiment is shown in FIG. 8, wherein a plurality of guide elements (27, 28, 29, 30) are provided, which are made in one piece and are attached to the sley (1) as only one guide means (18).
  • the two guide elements (27 and 28) of the only one guide means (18) work together with the gripper belt (7). If the guide means (18) is rotated through an angle of 180 ° (FIG. 9), the guide elements (29 and 30) are brought into such a position that they work together with the gripper belt (7) and thereby the gripper belt (7) Border on the side and guide on the top and bottom.
  • the guide means (18), which contains the guide elements (27 to 30) and the lugs (20), is attached directly to the sley profile (4), the screw means (19) being easily accessible here, too, because the heads are arranged on the side facing away from the reed.
  • FIG. 10 shows an embodiment with guide means (18, 18 ') arranged on both sides of the gripper belt (7), as in the embodiments according to FIGS. 1 to 7, wherein a guide means (18) with guide elements (31 and 32) and a Guide means (18 ') with guide elements (33 and 34) are provided.
  • the guide elements (31 and 33) are designed in such a way that the looper belt (7) can be guided on the lower warp threads (9).
  • an elastic covering (35) is provided on the profile (16).
  • FIG. 11 the embodiment according to FIG.
  • a further embodiment is shown, wherein a plurality of guide elements (36, 37, 38, 39) are provided on a guide means (18 '), two guide elements (36, 37 and 38, 39) each in the running direction of the Gripper belt (7) are successively arranged at a distance.
  • the guide means (18 ') can be fastened to the profile (16) with two screw means (19). In this case, the lugs (20) for positioning the guide means (18) are no longer required.
  • a known guide means is attached to the profile (16) with only one guide element (40) on the opposite side of the gripper belt (7).
  • FIG. 14 shows a varied embodiment of the embodiment shown in FIG. 2.
  • the guide elements (12 and 14) of the guide means (18 '), which work together with the gripper belt (7), are located transversely to the running direction of the gripper belt - offset levels.
  • the guide elements (13 and 15) are also in offset planes.
  • the guide means (18, 18 ') with the guide elements (12, 13 and 14, 15 and 22 to 25 and 27 to 30 and 31, 32 and 33, 34 and 36 to 39) each have at least two guide elements , and that optionally at least one guide element can cooperate with the gripper belt (7), while at least one other guide element does not cooperate with the gripper belt (7).
  • the guide means (18, 18 ') with the guide elements can work together with the gripper belt (7).
  • the guide means (18) has three guide elements, which are arranged in a star shape at an angle of 120 °, wherein one of these guide elements can cooperate with the gripper belt (7).
  • the device according to the invention for guiding a grip belt is of course not limited to the embodiments described as an example and shown in the figures and can be implemented in various other shapes and dimensions within the scope of the invention.
