Abstract:
A blower nozzle provided for the weft thread insertion is associated with the monolithic shed holder element for the weaving rotor of a series shed weaving machine. The shed holder element is manufactured from a piece of metal. The blower nozzle is integrated into the shed holder element and comprises at least one bore placed in the shed holder element.
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° 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).
Abstract:
In a multi-phase weaving machine, an apparatus (16) for monitoring warp yarn movement (3a, 3b) in particular leno warp yarns. The drawing-off movement or the drawing-off speed of the warp yarns (3a, 3b) can be detected by an electronic sensor (6a, 6b; 6c) so that it can in particular be determined whether the drawing-off movement or the drawing-off speed has a very low or relatively large value. If the value is very low, in particular when the warp yarn is standing still while the weaving process is running, it can be concluded that the warp yarn has broken. If the value of the drawing-off speed lies above a preset threshold value it can be concluded that the warp yarn is being driven in an undesired manner so that an error signal (13) is produced in order to interrupt the weaving process.
