Definitions

  • the invention relates to a device for fastening an auxiliary member, adjustable in the weft direction, to the reed of a defenseless weaving machine.
  • Protective weaving loom means in particular a weaving machine of the type in which a conveyor tunnel for measured weft pieces is formed on the reed, with a blowing nozzle for inserting the weft pieces at one end of the weaving shed and as an auxiliary organ near the other end of the shed a device working with an air stream for collecting and stretching the inserted weft pieces or a device for perceiving the inserted weft threads or a combination of such devices is provided, which device has a collecting channel connected to the effective part of the conveying channel. and is fastened adjustable in the weft direction against the stop side of the reed.
  • Such a weaving machine is used in cases in which cloths of different widths are to be weavable on the machine. This means that the reed on the side facing away from the weft conveyor protrudes over a variable length outside the edge of the cloth and that only the part of the conveyor tunnel lying within the cloth width is used effectively.
  • the device for extension and / or perception is now attached to the protruding reed part.
  • Examples of known weaving machines of this type are, for example, those according to the American patents 3,880,198 and 3,901,286.
  • the sliding attachment to the reed takes place by means of a fastening clamp, which in one case on the reed beam and in the other case on the attacks the top of the reed.
  • the invention aims at an improved attachment of the auxiliary member to the reed, which in particular better that in the reed stop movements occurring mass forces is adjusted.
  • the auxiliary member has at least one flange, which passes to the back side of the R iets extends between two adjacent reed lamellae, whereby the protruding on the rear side of the reed flange having an opening for insertion of a bolt element of the toggle type.
  • the stretching device can be firmly and easily tightened to the stop side of the protruding reed part, while the position of the auxiliary member can be adjusted in relatively small steps, which correspond to the thickness of a reed slat.
  • the locking element is formed by a bolt, of which a central part engaging with the projecting flange part lies a little eccentrically with respect to the two end parts of the bolt.
  • removable and fixable support blocks flattened at least on one side, are provided on the bolt ends.
  • This design has the advantage that when the stretching device is tightened (by rotating the bolt) to the stop side, the bolt ends acting as toggle cams do not (directly) come into contact with the reed (according to an unfavorable line contact), but above that with their flat side to the rear of the reed and thus little stress on the separate reed slats.
  • the air jet responsible for the stretching of the weft thread pieces entered in the shed is preferably directed in a manner as described in the American patent specification 4,096,889.
  • air flow and "air jet”
  • air jet another suitable flowing fluid could be used for transporting and stretching the weft thread pieces which were successively entered in the shed .
  • air is therefore to be understood broadly.
  • Fig. 1 the reed is denoted by 1, which can be moved in the direction of arrow I about an axis of rotation not shown in the drawing to and fro between the retracted position shown in the drawing and the stop position.
  • the actual reed is formed in a known manner from a row of reed slats 2 arranged side by side in the width direction of the machine, which are enclosed at the bottom in the reed beam 3 and inserted into a reed rail 4 at the top.
  • a measured weft thread piece is entered by means of a blowing nozzle 10 arranged on one side of the shed
  • the weft thread piece inserted by the air-fed blowing nozzle 10 actually takes place through the tunnel 11, which is delimited by all the recesses in the reed lamellae 2, which recesses are open in the direction of the stop line 9.
  • the promotion of the weft by the shed or through the reed tunnel 11 is supported, in particular with larger weaving widths, for example by means of intermediate blowing nozzles which are carried by the reed.
  • These auxiliary blowing nozzles are not shown in the drawing.
  • the stretching device 12 is mounted on the end part of the reed which faces away from the blowing nozzle 10 and which projects outside the edge of the cloth.
  • This stretching device consists of a shaped piece, the side of which faces the reed is shaped in accordance with the profile of the reed lamellae (see in particular FIG. 2).
  • the shaped piece of the stretching device has a rib 13 which fits tightly in the part of the reed tunnel 11 lying outside the shed.
  • a collecting channel 14 (see FIG. 2) is excluded, which connects to the "effective" part of the reed tunnel 11 lying within the width of the woven cloth.
  • the passage of the collecting channel 14 gradually decreases in the firing direction from the entrance opening 15 (see FIG. 2), the cross section of which is almost the same size as that of the conveying tunnel 11.
  • the exit opening of the collecting channel, designated 16 in FIG. 1 has a passage which is only a fraction of the Riettunnel cross-section.
  • the flange 17 protrudes a certain distance from the rear of the reed.
  • this projecting part there is an opening 18 in which a locking bolt 19 can be received, the diameter of which corresponds to that of the opening 18.
  • the locking bolt 19 has a central part 19a with a somewhat smaller diameter, which is eccentric with respect to the two end parts 19b. So that the shaped piece arranged in the desired position on the stop side of the protruding reed part can now be fixed, after inserting the locking bolt 19, the support blocks designated 20, flattened on one side, are each arranged on a bolt end 19b, in such a way that the blocks with theirs flattened side to be placed on the back of the reed. Thereafter, the bolt 19, while the middle part thereof is in the opening 18 of the flange 17, is rotated in such a way that the bolt ends 19 act as toggle cams within the support blocks 20 and place these support blocks firmly against the rear of the reed.
  • the stretching device can also be released in a simple manner by means of a rotary movement in the opposite direction and the removal of the support blocks, as well as the removal of the locking bolt.
  • a flange part 21 which also fits between two adjacent reed slats and contributes to a good fixation of the stretching device 12.
  • the stretching device 12 receives its stretching effect from an air jet, which is directed transversely in the vicinity of the outlet opening 15, namely approximately perpendicularly through the collecting channel.
  • a feed channel 22 is provided in the fitting, which can be connected to a compressed air source at 23 and opens in the vicinity of the outlet opening in the lower wall of the collecting channel 14, just opposite the collecting opening of a further mixing tube 24, which the head of the inserted weft piece under the influence of the air jet records.
  • This stretching principle corresponds in principle to that of the stretching device according to the American patent specification 4,096,889.
  • a shot detection device is attached to the part of the reed protruding outside the cloth edge, for example in a location which lies between the cloth edge and the stretching device.
  • the fastening method shown in FIG. 3 differs from that according to FIGS. 1 and 2 in that there are two fastening flanges 17 ', each of which extends between two adjacent reed fins.
  • These fastening flanges (only one of which is visible in the cross-sectional drawing according to FIG. 3) are connected to the front (8ntschsseite) of the reed 1 by means of an upper and a lower connecting web part 25. 26 connected.
  • the distance between the flanges is chosen so that an upper and a lower block 27 or between them.
  • each block 27 resp. 28 there is a room 29 for receiving a transmitter. a receiver of the shot detection device.
  • the part 27a of the upper block 27, which lies between the lower edge of the web 25 and the upper edge of the tunnel 11, viewed in the direction perpendicular to the plane of the drawing, is narrowed in such a way that it fits between the tongues of two adjacent reed slats projecting forward.
  • the same applies to the part 28a of the lower block 28 which lies between the upper edge of the web 26 and the lower edge of the tunnel 11.
  • the locking bolt 19 'and the parts 20' acting as toggle cams form one piece and the opening 18 'is designed as a slot which is open at one end and in such a way that the locking bolt 18' is from the Bottom can be inserted from.
  • One end of a flexible element 30 is attached to the parts 20 'lying eccentrically opposite the locking bolt 18', the other end of which is connected via a spring 31 to an element 32 which hooks over the upper reed rail 4. Under the influence of the spring 31, the flexible element 30 tries to unwind from the eccentric parts 20 ', as a result of which a counterclockwise moment is exerted on these parts, which, as viewed in FIG. 3, moves the flanges 17' to the right and thereby attracting blocks 27 and 28 to the front of the reed.
