1. A weaving machine, comprising:
a shed forming device that opens and closes a loom shed formed by a plurality of warp threads of a fabric being woven by the weaving machine;
a weft insertion device that inserts weft threads through the open loom shed;
a weaving reed that beats up the weft threads at a beat up plane against an edge of the woven fabric;
a drawing off device that draws off the woven fabric;
a guide device comprising at least one guide unit that extends at least partially over a width of the woven fabric, the guide unit driven by a drive and comprising a guide section that is positionable in a direction of thickness of the woven fabric to contact and guide the woven fabric in an area of the beat up plane, the guide unit being one or both of an upper guide unit that contacts a top surface of the woven fabric or a lower guide unit that contacts a bottom surface of the woven fabric; and
a control unit in communication with the drive, the control unit configured to control movement of the guide unit in alternate directions along the direction of thickness of the woven fabric as the fabric is being woven in synch with continuous alternating vertical movement of a weaving location along an edge of the fabric where the warp threads are woven into the fabric such that the weft insertion device is positioned in the open loom shed prior to weft insertion so as to be guided through the open loom shed in a collision free manner relative to the warp threads, wherein the control unit controls the movement of the guide unit in the alternate directions based on information related to one or both of a structure of the woven fabric in the area of the beat up plane or a position of the warp threads in the open loom shed.
