摘要:
A device for inserting of weft threads in an air jet weaving machine comprising at least one set of main nozzles (13, 14) which are mounted in series, to which each time a regulating valve (21, 22) is assigned, is provided with a control and regulating unit (17) which defines the settings of the regulating valves (21, 22) of a set of main nozzles (13, 14) with respect to one another, in order to form an overall value for the intensity of the impulse transmission of the set of main nozzles.
摘要:
A device for supplying weft threads in airjet weaving machines includes at least one nozzle connected to a compressed air source, a buffer tank, a cutoff valve placed in a funnel between the compressed air source and the nozzle, and a controlled throttling device. The throttling device is mounted downstream from the buffer tank and in the immediate surroundings of the cutoff valve, and includes the funnel, a rotary throttling element, and a motor for rotating the throttling element. The funnel is divided into an inlet funnel and an outlet funnel connected to the inlet funnel. The rotary throttling element fits within the inlet funnel and rotates to selectively block an entry to the outlet funnel according to the degree of rotation of the throttling device.
摘要:
A device for inserting of weft threads in an air jet weaving machine comprising at least one set of main nozzles (13, 14) which are mounted in series, and to which individual regulating valves (21, 22) are assigned, is provided with a control and regulating unit (17) which defines the individual settings of the regulating valves (21, 22) with respect to one another, in order to form an overall value for the intensity of the impulse transmission of the set of main nozzles with each regulating valve contributing a proportion of the overall impulse intensity.
摘要:
Apparatus for supplying compressed air to a main blowing nozzle of an airjet loom for filling insertions includes an integrated air feed unit including an intake directly connected to the compressed air supply, an outlet connected to the main blowing nozzle and air flow control valves including valve drivers. Main and bypass ducts provide communication between the intake and the outlet with the airflow control valves controlling the supply of air to the outlet of the air feed unit. The air flow control valves include a check valve arranged to control in an on/off manner the supply of compressed air from the main duct to the outlet; a first adjustable throttling valve arranged to control the pressure of compressed air supplied to the outlet during filling insertions when the check valve is open and a second adjustable throttling valve arranged to control the pressure of compressed air supplied to the outlet between filling insertions when the check valve is closed. A pressure control monitor may be connected to the air feed unit for supplying pressure signals to the loom control system. Individual main nozzles may be provided with respective individual integrated air feed units.

摘要:
A device for stretching an inserted filling (14), in particular for use in an airjet loom, includes a channel (5) adjoining a filling insertion conduit (4) of a reed (3), a blow nozzle directed at a branch channel intersecting the channel (5) in substantially perpendicular manner discharging into the channel (5), and at least one deflection location for the filling (14). The deflection location consists of a wear-resistant element (7, 10, 11) that extends substantially transversely to the direction of insertion (A) of the filling.
摘要:
A device for stretching a weft thread in weaving machines includes a stretching nozzle mounted on the sley of the weaving machine and a blower device for removing weft threads from the stretching nozzle. The blower device is mounted on the sley near the stretching nozzle.
摘要:
A device for the insertion of weft thread into a shed of air insertion looms primarily consists of the combination of a main nozzle, and of at least one auxiliary nozzle fixedly mounted before the main nozzle, the latter having an adjustable flow-through aperture for regulating the jet insertion medium. Associated with each auxiliary nozzle, a control means is utilized for the adjustment of the flow-through aperture. Various embodiments of aperture control are described.
