Apparatus for making available a leno thread for a weaving machine

Apparatus in accordance with any one of the preceding claims, characterized in that the thread guiding element (8) is designed to be substantially U-shaped and has two limbs (8a, 8b);

• and in that the one limb (8a) extends inside the shaft (4) in the direction of the axis of rotation (A).

Apparatus in accordance with any one of the preceding claims, characterized in that the holder apparatus (6) comprises a circular base plate (6a) which is arranged perpendicularly to the axis of rotation (A);

• and in that a circular guide element (10) is arranged coaxially to the axis of rotation (A) with a spacing in the direction of extent of the axis of rotation (A) with respect to the base plate (6a).

Apparatus in accordance with any one of the preceding claims, characterized in that one eye (13) for guiding the leno warp threads (2a, 3a) is arranged in the region of the axis of rotation (A) with such a spacing with respect to the holder apparatus (6) that the eye (13) projects in the direction of extent of the axis of rotation (A) beyond the leno thread bobbins (2, 3) to be accommodated.

Apparatus in accordance with any one of the preceding claims, characterized in that the shaft (4) is rotatably journalled in a securable bearing (11).

Apparatus in accordance with any one of the preceding claims, characterized in that the holder apparatus (6) comprises a thread guidance means (9a) which is arranged relative to the positioning of an inserted leno thread bobbin (2, 3) in such a manner that the leno thread (2a, 3a) can be drawn off from the leno thread bobbin (2, 3) substantially perpendicularly to the longitudinal extent of the latter.

Apparatus in accordance with any one of the preceding claims, characterized in that the holder apparatus (6) comprises a sensor (14a, 14b, 14c, 14d) which permits a breakage of a leno thread (2a, 3a) to be detected.

Apparatus in accordance with any one of the preceding claims, characterized in that the holder apparatus (6) comprises a thread guidance means (9a) for guiding the leno thread (2a, 3a) which is drawn off from the leno thread bobbin (2, 3);

• and in that a braking means (9c) which acts on the leno thread bobbin (2, 3) is connected to the thread guidance means (9a) in order to cause a braking torque on the leno thread bobbin (2, 3) which is dependent on the position of the thread guidance means (9a).

Apparatus in accordance with any one of the preceding claims, characterized in that a thread twisting element (15) which can be driven so as to rotate synchronously to the thread guiding element (8) is arranged after the thread guiding element (8) in the draw-off direction of the leno warp threads (2a, 3a).

Weaving machine comprising an apparatus in accordance with any one of the preceding claims.
