Title: Apparatus and method for the preparation of a leno thread for a weaving machine

Abstract: The apparatus (1) for the preparation of at least two leno warp threads (6a, 7a) for a weaving machine (13; 17) comprises a first holder apparatus (7b) for the reception of a first leno thread bobbin (7) as well as a second holder apparatus (6b) for the reception of a second leno thread bobbin (6) as well as a rotatably journalled thread guide apparatus (3) which supplies the leno warp threads (6a, 7a) to a weaving machine (13; 17) which is placed after it in the direction of thread travel (F), with the first holder apparatus (7b) being arranged first in the direction of thread travel (F), being followed by the second holder apparatus (6b), and being then followed by the thread guide apparatus (3), and with a thread guide element (2m) for the guiding of the first leno warp thread (7a), which is to be drawn off from the first warp thread bobbin (7), being arranged substantially in the direction of thread travel (F) and extending adjacent to the second holder apparatus (6b), with the thread guide element (2m) having an entry opening (2z) for the first leno warp thread (7a) which is arranged ahead of the second holder apparatus (6b) in the direction of thread travel (F), and with the thread guide element (2m) being designed to extend in such a manner and is rotatable through 360.degree. and drivably journalled about an axis of rotation which extends substantially in the direction of thread travel (F) in such a manner that the second warp thread bobbin (6), which is arrangeable on the second holder apparatus (6b), can be circled by the thread guide element (2m) in order to twist the first leno warp thread (6a), which emerges from the thread guide element (2m), together with the second leno warp thread (7a), which extends between the second warp thread bobbin (6) and the thread guide apparatus (3).
