A shed forming device for a weaving machine, comprising a working space (3) in which shed forming systems having selection means for the positioning of warp threads are provided, and ventilation means (7) to create an air flow (A) in this working space (3), wherein the ventilation means (7) interact with regulating means (8, 9, 10) for automatically regulating the air flow rate as a function of at least one of the following measured parameters: the flow rate and the velocity of the air flow (A) and the air pressure in the working space (3). As a result, the air flow rate can be rapidly adapted to changing conditions and can always be appropriate for efficient cooling and for creation of an overpressure.

The disclosure concerns a shed-forming device including a jacquard device in which the heddles, are connected to a pull-back element, for exerting a downward force on the heddle, wherein for each heddle, a yarn tensioning element is provided to change the yarn tension in at least one associated warp thread, and where a control or steering unit is provided for steering or controlling the yarn tension in at least one associated warp thread, separately for each heddle, in order to bring the total downward force on the heddle to a specific value or vary this according to a specific profile.

A clamping apparatus provides a releasable connection of a harness cord to a lifting heddle of a leno weave apparatus, wherein the releasable connection is configured as a clamping connection. The clamping apparatus has a clamping wedge and a wedge receiver device arranged at the end of the lifting heddle. The wedge receiver device displaceably receives the clamping wedge in the longitudinal direction of the lifting heddle. The harness cord is clampingly grippable between the wedge receiver device and the clamping wedge structure is provided for fixing the clamping wedge in the clamping receiver device.

Jacquard loom for producing a woven preform from several warp yarns and several weft yarns, the loom including a device for taking up the preform when it is being produced, in order to move it along an axis (X) as it is being formed, which axis is substantially parallel to a production direction for the preform, characterised in that the loom also includes a control for rotating the preform, substantially about the axis.
