Embodiment Construction

[0064] figure 1 A schematic side view of a possible embodiment of the weaving machine 1 is shown. A plurality of warp threads 80 extending side by side are provided, for example, by a warp beam 2 (alternatively by a creel) and are conveyed along the warp direction KR (see arrow) via the back rest 3 and after passing the warp monitor 4 to the shedding device 5, which opens The means are preferably formed by threads 6 known to be oscillating and movable against each other in order to open or close the weaving shed 9 . The opening means 5 are according to a preferred embodiment of the jacquard type.

[0065] The weft thread feeder 7 (shown only schematically) has a weft thread feeder 8 , which is designed in the present case as a thread gripper, and which conveys the weft thread through an open weaving shed 9 . Furthermore, the loom 1 has a weaving board 10 , by means of which the incoming weft threads can be brought into contact with so-called connection points 11 of the alrea...

Abstract

The invention relates to various designs of a loom, which designs can be combined with one another, said loom comprising at least one guiding device having at least one guiding unit (32, 34) for the contacting guidance of a woven fabric (82) in the region of the reed beat-up plane (14). According to one embodiment, a control unit (15) is provided, which is designed to control at least one drive (38, 39) for the at least one guiding unit (32, 34). For the actuation, the control unit (15) processes information related to the woven-fabric structure in the region of the reed beat-up plane (14) and / or information regarding the position of the warp threads (80a, 80b) in the open shed. The invention further relates to methods for guiding a woven fabric in the region of the reed beat-up plane (14).

Description

technical field [0001] The invention relates to a weaving machine according to the preambles of the independent claims. The invention likewise relates to a corresponding method. Background technique [0002] Such looms, for example in the form of jig looms and air looms, have been known for a long time. What is common to them is that a plurality of warp threads running side by side in the production direction are raised or lowered by means of a shedding device in order to form an open shed through which (at least) one weft thread is fed. Subsequently, the shed is closed again, and the weft thread rests on the connection point through the weaving plate, so that the shed is opened again. The fabric is continuously drawn out by means of a pulling device and is wound, for example, onto a cloth roll, or the fabric is removed in the horizontal position of the weaving machine. [0003] A disadvantage of the known weaving machines is that a reliable weaving cannot always be ensur...
