摘要:
In an air jet weaving machine having: a picking nozzle (61, 62) outside the shed (15); and a weft yarn deflector (7, 90, 23) disposed between such nozzle and the shed (15) and operative to keep the weft yarn (5) away from the shed in response to a machine stop signal caused by a disturbance, a conveying line (22) for the deflected weft yarn (5) is received in the sley (10). The conveying line (22) is closed at its entry end by an end member (24) into which a funnel (23) of the weft yarn deflector leads. A receiver (30) having a suction or intake duct (32) is disposed at the exit end of the conveying line, the duct entry aperture being so dimensioned that the exit aperture of the conveying line (22) leads freely into the extraction or exhaust duct (32) in all positions of the sley (10).
摘要:
Clutch mechanism, particularly for looms. The mechanism has a housing, in which a pair of opposed electromagnets are stationarily mounted, between which there is arranged a friction disc mounted axially displaceably on a driven shaft. A rotor, fixedly connected to a control shaft disposed coaxially of the driven shaft, is disposed between one electromagnet and the friction disc for selective driving engagement therewith.

The present invention relates to improvements in shed locating devices associated with dobbies and other weaving systems. A device is provided to enable the dobby shaft to remain coupled to the loom shaft whilst being connected to an auxiliary motor and gear reducer for providing low-speed drive of the loom and the dobby for use when working on the weaving system. The same motor and gear reducer are also used during shed locating operations. The mechanisms for shifting between the normal operation of the loom and dobby, the shed locating operation, and the low speed drive of the loom and dobby are electrically controlled.
摘要:
Apparatus for detecting whether one thread selected from a number of threads is in motion, while no other thread is in motion, or whether a set of threads selected from a number of sets, each having two or more threads, is in motion, while no other set is in motion. The apparatus includes a signal generator associated with each thread for generating an electric signal in response to the movement of the associated thread. The signal generators are coupled sequentially to signal indication apparatus. If the prescribed thread movement is detected, the signal generating apparatus inhibits generation of an alarm indication. If the prescribed thread movement is not detected, the signal generating apparatus activates a trigger device to initiate an alarm.
