Patent ID: 7753084

Claim:
Clamping arrangement including two clamping devices on an air-jet weaving machine, which comprises respectively for each clamping device at least one main blow nozzle with a mixing tube for the insertion of a weft thread into a loom shed by a transport fluid ejected from the main blow nozzle, and an actuator arranged outside of the mixing tube, and a movable clamping element, which, through activating of the actuator, is selectively brought into a clamping position in which the weft thread is tightly clamped on a path location of the main blow nozzle and the mixing tube or into a release position in which the weft thread is not clamped, and is held in the respective position, characterized in that the clamping arrangement further comprises at least one holding magnet ( 11 ), and each respective said clamping element ( 7 ) is at least area-wise embodied ferromagnetically, and is arranged so that a clamping force of the respective clamping element ( 7 ) in the clamping position thereof is magnetically strengthened by an influence of the holding magnet, characterized in that the two clamping devices ( 5 ) with the two mixing tubes ( 2 ) lying directly next to one another are combined together to form thereof a module unit ( 18 ), whereby the two mixing tubes ( 2 ) lie in one plane in a mirror-symmetrical arrangement with the actuators ( 6 ) facing outwardly, and characterized said holding magnet is a common holding magnet ( 11 ) that is allocated to the two mixing tubes ( 2 ) of the module unit ( 18 ).
