Embodiment Construction

[0019] 1 to 4 show schematic diagrams of the weft insertion region of a weaving machine, wherein only the parts that are relevant to the invention are shown. All remaining features of the loom are prior art.

[0020] Figures 1 and 3 show the weaving area of ​​a loom in which the warp thread 2 is moved towards an open shed 6 by means of a shed forming device (Fachbildevorrichtung) 4 such as a Jacquard device, in which it passes through a weft insertion device 8 Insert weft yarn 10. By means of the reed 12 the weft thread stops on a stop edge 14 so that a cloth 16 is formed.

[0021] The weft insertion device 8 is constructed pneumatically and has a nozzle block 20, which in this example has eight blowing nozzles 22, which are arranged in pairs in the transverse direction Q according to FIG. 4, wherein according to figure 2 , four pairs of such nozzles are stacked in the height direction H. The mouth block 22 is arranged swingably in the lateral direction Q on a vertical axis...

Abstract

The weaving machine comprises a pneumatic weft insertion. It is fitted with a weaving reed (12), wherein a guiding device (42) is associated with a guiding channel (40) for a weft thread (10).The guiding channel (10) comprising the weaving reed (12) can be pivoted between an insertion position and a stop position for the weft thread (10). Also, a fixed weft thread insertion device (8), which comprises at least two blast nozzles (22), is associated with the guiding channel (40) in the insertion position. A fixed blade (46) is used to cut the inserted weft thread (10). The blast nozzles (22) are pivotably mounted in the transversal direction (Q) counter to the blade (46) in order to improve the weaving machine and are connected by means of a motor drive device (28) in order to displace the blast nozzles (22) counter to the blade (46).

Description

technical field [0001] The invention relates to a weaving machine with pneumatic weft insertion according to the general concept of claim 1 . Background technique [0002] A loom of the above-mentioned type with pneumatic weft insertion is known, for example, from WO 97 / 13901. The weaving machine has a reed associated with a guide device with a guide channel for the weft thread. The guide channel and the reed can be pivoted for the weft thread between an introduction position and a rest position. In addition, the guide channel in the insertion position is associated with a stationary weft insertion device with a blowing nozzle, that is, the blowing nozzle is arranged independently of the reed and therefore does not influence the movement of the reed on the one hand, but also itself on the other hand. Unaffected by reed movement. Scissors are used to cut the incoming weft yarn. The blowing nozzles are arranged pivotably in the height direction and are driven by a jacquard...
