Definitions
- the invention relates to a method for removing a weft incorrectly inserted by a hydraulic pick into the shed of a weaving machine, in which a control system for detecting the incorrectly inserted weft performs the stopping of the machine, removes the incorrectly inserted weft and restarts the machine into production mode, whereby during the same revolution of the machine when the weft was improperly inserted (picked), the signal to stop the machine is generated by the control system of the machine, by which means interruption of the defectively inserted weft at the entrance of the shed is prevented.
- the operation of the machine is reversed to a state with an open shed position in which the weft was not inserted properly, whereupon a new weft is inserted as static weft insertion without the motion of the opened branches of the warp and without the motion of the means for transferring the new weft to the fell of the fabric being formed, by the new weft insertion the previously incorrectly inserted weft is removed from the opened shed, whereupon on the side of the shed remote from the picking nozzle it is determined whether the weft thread has been removed successfully and the machine is either restarted and switched into production mode or it is stopped and error signalling is initiated.
- the invention also relates to a device for removing a weft incorrectly inserted by a hydraulic pick into the shed of a hydraulic weaving machine, which comprises a measuring device of the length of the weft thread, aligned with a hydraulic picking nozzle, which is situated on one lateral side of the shed and is directed to the other side of the shed in the direction of the fabric being formed, whereby a weft stop is mounted on the machine frame and in the area between the picking nozzle and the proximal edge of the fabric being formed a means for interrupting the weft is mounted on the machine frame, the picking nozzle being connected to a pump of the weft insertion system, which is connected to an individual drive, which is mechanically independent of the other subunits and elements of the hydraulic weaving machine, whereby the measuring device, the pump drive, the means for interrupting the weft and the weft stop are connected to the control system of the weaving machine.
- the weft thread is inserted into the shed of the weaving machine by a flow of a fluid, which is launched into the shed of the hydraulic weaving machine together with the weft.
- the pressure fluid stream carries the weft through the shed and transports the weft end from one side of the shed to the other side of the shed, thereby inserting the weft into the shed along its entire length, i.e. across the full weaving width of the fabric being formed.
- the individual devices of the hydraulic weaving machine which participate in the weft insertion process, particularly a mechanism for shed formation, a device for the preparation and insertion of the weft thread into the shed, a hydraulic pump which supplies an appropriate stream of the picking fluid to the picking nozzle at required moments of the weaving cycle, are mutually coupled by mechanical couplings to be properly synchronized.
- weft insertion into the shed the operator steps on the pedal for manual control of weft insertion, by which means the required dose of the picking fluid is manually fed to the picking nozzle and one weft insertion operation is performed (i.e. weft insertion into the shed).
- CZ 1990-2875 A3 discloses a solution of removing a weft on an air jet weaving machine, in which the removal of a defectively inserted weft is performed by inserting the following uninterrupted weft while varying the mutual position of the weft insertion means and a binding point. That means that this is a non-static method of weft insertion, which is highly demanding in terms of the speed of weft insertion, synchronization of the individual parts of the machine and acceleration of the machine from standstill so as to perform "cleaning" weft insertion.

- the invention will be described referring to an example of embodiment of a hydraulic weaving machine, which is widely known, and therefore in the following text no other parts of the hydraulic weaving machine will be mentioned but those parts which are used to implement this invention.
- the hydraulic weaving machine comprises an unillustrated system of warp threads, which are guided to a mechanism for shed formation.
- a beating-up device is located behind the mechanism for shed formation in the direction of the motion of warp threads. The final member of the beating-up device ensures the transfer of the weft 9 from the shed to the fell of the fabric being formed.
- the woven fabric is wound onto a cloth beam.
- the weft thread is properly arranged in the machine construction, e.g., it is wound on a suitable bobbin.
- the weft thread is guided to a weft length measuring device 2 , from which it is guided further on to a picking nozzle 5 .
- the system consisting of the measuring device 2 and the nozzle 5 is arranged on one lateral side of the shed and is directed to the other side of the shed, i.e. in the direction of the width of the fabric being formed, as usually.
- On the opposite side of the shed i.e.
- a weft stop 7 and a detector 8 of the weft 9 removal are mounted on the machine frame.
- a means 6 for interrupting the weft 9 is mounted on the machine frame.
- the picking nozzle 5 is with its hydraulic distribution system connected to the outlet of the fluid from the pump 4 of the weft insertion system, whereby the mechanical drive of the pump 4 of the weft insertion system is secured by connecting the pump 4 to an individual drive 3 .
- the individual drive 3 of the pump 4 of the weft insertion system is mechanically independent of the other subunits and elements of the hydraulic weaving machine.
- the measuring device 2 of the weft, the individual drive 3 of the pump 4 of the weft insertion system, the means 6 for interrupting the weft 9 , the weft stop 7 and the sensor 8 of the weft 9 removal are connected to the control system 1 of the weaving machine.
- the control system 1 of the weaving machine controls the operation and coordination of the activities of the individual subunits and means of the weaving machine, so that fabric with the required parameters will be produced. That means that the standard weaving process takes place, in which weft threads 9 are blown successively into the shed by the stream of the picking fluid ejected by the picking nozzle 5 , whereby after each successful insertion, which is checked by the weft stop 7 on the other side of the shed, the weft 9 is separated from the other weft threads by the means 6 for interrupting the weft 9 and subsequently the weft 9 is transferred by a beating-up mechanism to the fell of the woven fabric. In this manner, weaving cycles are continuously repeated and fabric is produced.
- the weft stop 7 detects a state in which the weft 9 with its front end did not extend over the entire width of the weft 9 insertion, i.e. the entire width of the woven fabric enlarged by edge strips, in which the weft 9 exceeds the width of the woven fabric, it emits a signal about this state to the control system 1 , which generates a signal to stop the machine.
- the signal to stop the machine is generated already during the same revolution of the machine in which the incorrectly inserted weft 9 was detected.
- the above-mentioned signal to stop the machine prevents the interruption of the detected incorrectly inserted weft 9 at the entrance into the shed by severing from the rest of the weft thread in the measuring device 2 of the weft 9 .
- this interruption is performed by the means 6 for interrupting the weft 9 .
- the machine operation is automatically reversed by the control system 1 , i.e. the individual parts of the machine are put in reverse operation to such a position of the individual components of the machine (state), in which the shed with the detected defectively inserted weft 9 is opened, whereby this detected defectively inserted weft 9 is at the entrance into its shed still connected to the weft 9 supply on the measuring device 2 .
- the detector 8 of the weft 9 removal After inserting the new weft 9 into the shed and therefore after the assumed pulling out (ejection, expulsion, removal) of the previously incorrectly inserted weft 9, the detector 8 of the weft 9 removal, which is located on the side of the shed remote from the picking nozzle 5 , is activated.
- the detector 8 of the weft 9 removal finds out how many wefts 9 are physically present in the control zone, i.e. at the end of the shed behind the weft stop 7 .
- control system 1 performs individual transfer of this new weft 9 to the fell of the fabric being formed and puts the hydraulic weaving machine into operating mode of standard fabric production, which means that automatic restart of the hydraulic weaving machine is performed and the machine continues producing the required fabric.
- weft thread 9 there are more than one weft thread 9 in the control zone, e.g., two or three weft threads, whereby this could be a loop formed by one weft thread 9 when at least two parts of one weft 9 are situated in the control zone, or, on the contrary, there is no weft 9 in the control zone, it means that the attempt to remove the defectively inserted weft 9 has failed.
- the control system 1 decides on further action according to the nature of the failure. For example, if in the control zone there are more weft threads 9 than one, the whole process, as well as the machine, is automatically stopped and signalling is initiated to show that the defectively inserted weft 9 has not been automatically removed. Similarly, if there is no weft 9 in the control zone, the whole process, as well as the machine, is automatically stopped and signalling is initiated to show that the new weft has not been inserted.
- the detector 8 of the weft 9 removal comprises an ultrasonic sensor 80 , which is mounted reversibly displaceably on the machine frame in the control zone transversely to the direction of the insertion (picking) of the weft threads 9 .
- a collecting plate 81 e.g. sheet metal, with a longitudinal opening 810 .
- the collecting plate 81 extends from the beating-up position of the weaving reed 0, see Fig. 2 , as far as to the position of the weaving reed 0 at back dead centre below the space defined by the size of the shed in a vertical plane, see Fig. 3 .
- the position of the collecting plate 81 ensures that there are no parts of the weft 9 deposited on its surface. Moreover, the collecting plate 81 is during the machine operation very intensely sprayed by the disintegrating water jet of the hydraulic weft insertion system.
- the ultrasonic sensor 80 is mounted on a piston rod 820 of a pneumatic cylinder 82 , which is via an unillustrated electro-pneumatic valve connected to a source of compressed air and to the control system 1 .
- the ultrasonic sensor 80 is further aligned with a air blower nozzle 83 , which is also connected to the source of compressed air whose supply is controlled by the above-mentioned electro-pneumatic valve.
- the weft 9 properly inserted into the shed lies before being transferred to the fell of the woven fabric on the collecting plate 81 over the longitudinal opening 810 formed in it.
- the supersonic sensor 80 is blown over by the air blower nozzle 83 , whereupon the supersonic sensor 80 moves across the weft insertion path above the collecting plate 81 and the longitudinal opening 810 formed in it.
- this motion in reality it represents a path of, e.g., approximately 50mm, the ultrasonic sensor 80 moves at a certain distance above the collecting plate 81 as far as to the back position of the weaving reed 0 , as is shown in Fig.
- control system 1 decides on further action, i.e. automatic restart or signaling failure status (due to the failure to remove the incorrectly inserted weft 9 or failure to insert a new weft 9 ), as has been described above.
- the detector 8 of the weft 9 removal comprises an optical sensor instead of an ultrasonic sensor 80 , which is mounted either on the same movable structure as the above-described ultrasonic sensor 80 , or on another suitable structure allowing the optical sensor to move within the control zone.
- the optical sensor is aligned with a cleaning device, e.g., a air blower nozzle, connected to the source of compressed air and serving to remove the picking fluid and impurities from the optical elements of the optical sensor.
- the ultrasonic detector 80 is in the unillustrated exemplary embodiment mounted on another suitable structure allowing the movement of the ultrasonic sensor 80 within the control zone.

Description
- The invention relates to a method for removing a weft incorrectly inserted by a hydraulic pick into the shed of a weaving machine, in which a control system for detecting the incorrectly inserted weft performs the stopping of the machine, removes the incorrectly inserted weft and restarts the machine into production mode, whereby during the same revolution of the machine when the weft was improperly inserted (picked), the signal to stop the machine is generated by the control system of the machine, by which means interruption of the defectively inserted weft at the entrance of the shed is prevented. Subsequently, after the machine is stopped, the operation of the machine is reversed to a state with an open shed position in which the weft was not inserted properly, whereupon a new weft is inserted as static weft insertion without the motion of the opened branches of the warp and without the motion of the means for transferring the new weft to the fell of the fabric being formed, by the new weft insertion the previously incorrectly inserted weft is removed from the opened shed, whereupon on the side of the shed remote from the picking nozzle it is determined whether the weft thread has been removed successfully and the machine is either restarted and switched into production mode or it is stopped and error signalling is initiated.
- The invention also relates to a device for removing a weft incorrectly inserted by a hydraulic pick into the shed of a hydraulic weaving machine, which comprises a measuring device of the length of the weft thread, aligned with a hydraulic picking nozzle, which is situated on one lateral side of the shed and is directed to the other side of the shed in the direction of the fabric being formed, whereby a weft stop is mounted on the machine frame and in the area between the picking nozzle and the proximal edge of the fabric being formed a means for interrupting the weft is mounted on the machine frame, the picking nozzle being connected to a pump of the weft insertion system, which is connected to an individual drive, which is mechanically independent of the other subunits and elements of the hydraulic weaving machine, whereby the measuring device, the pump drive, the means for interrupting the weft and the weft stop are connected to the control system of the weaving machine.
- On hydraulic weaving machines the weft thread is inserted into the shed of the weaving machine by a flow of a fluid, which is launched into the shed of the hydraulic weaving machine together with the weft. The pressure fluid stream carries the weft through the shed and transports the weft end from one side of the shed to the other side of the shed, thereby inserting the weft into the shed along its entire length, i.e. across the full weaving width of the fabric being formed.
- The individual devices of the hydraulic weaving machine, which participate in the weft insertion process, particularly a mechanism for shed formation, a device for the preparation and insertion of the weft thread into the shed, a hydraulic pump which supplies an appropriate stream of the picking fluid to the picking nozzle at required moments of the weaving cycle, are mutually coupled by mechanical couplings to be properly synchronized.
- If for any reason a fault occurs in the weft insertion into the shed, e.g., the front end of the weft does not pass through the whole length of the shed, etc., it is necessary to stop the whole machine and remove this incorrectly inserted weft. Otherwise, a defect in the fabric would arise. The removal of the weft which was improperly inserted by a hydraulic weft insertion mechanism into the shed of the hydraulic weaving machine with a hydraulic weft insertion system into the shed is currently carried out in such a manner that after stopping the machine and opening the shed, the operator seizes the defectively inserted weft manually, in the best case using a special tool (a hook), and pulls it out (removes it) from the shed. Subsequently, while the machine is not working, the operator steps on the pedal for manual control of weft insertion, by which means the required dose of the picking fluid is manually fed to the picking nozzle and one weft insertion operation is performed (i.e. weft insertion into the shed). The operator checks whether the weft insertion was performed correctly and manually starts the machine, which continues weaving, wherein at first the weft that has been inserted in the shed is beaten up manually to the fell of the fabric being fomed and after that normal process of fabric formation continues.
-
CZ 1990-2875 A3 - The disadvantage of the background art is the necessity of manual or only a partially automated removal of the defectively inserted weft on the hydraulic weaving machine, which therefore requires the presence and activities of a human operator. Another drawback is the fact that removing the incorrectly inserted weft is time-consuming, which limits the effective use of the hydraulic weaving machine for fabric manufacturing.

claim 4. The principle of the device for removing a weft incorrectly inserted by a hydraulic pick into the shed of a hydraulic weaving machine consists in that on the side of the shed remote from the hydraulic picking nozzle behind created fabric is located a detector of the weft removal, which is also connected to the control system designated for detecting number of threads situated in its control zone. - The present invention enables to use a fully automatic removal of a weft incorrectly inserted by hydraulic weft insertion into the shed of a hydraulic weaving machine, which results not only in saving labour for the machine operation and other advantages, but also in increasing overall machine effectiveness by approximately 12 %.
- The invention is schematically represented in the drawing, where
Fig. 1 shows an arrangement of the parts of the hydraulic weaving machine used for removing the incorrectly inserted weft,Fig. 2 shows a detail of the area of sensing whether removal of the defectively inserted weft has been successful in the status without the inserted weft andFig. 3 shows a detail of the area of sensing whether removal of the defectively inserted weft has been successful in the status with the inserted weft. - The invention will be described referring to an example of embodiment of a hydraulic weaving machine, which is widely known, and therefore in the following text no other parts of the hydraulic weaving machine will be mentioned but those parts which are used to implement this invention. The hydraulic weaving machine comprises an unillustrated system of warp threads, which are guided to a mechanism for shed formation. A beating-up device is located behind the mechanism for shed formation in the direction of the motion of warp threads. The final member of the beating-up device ensures the transfer of the
weft 9 from the shed to the fell of the fabric being formed. The woven fabric is wound onto a cloth beam. - The weft thread is properly arranged in the machine construction, e.g., it is wound on a suitable bobbin. The weft thread is guided to a weft
length measuring device 2 , from which it is guided further on to a pickingnozzle 5. The system consisting of the measuringdevice 2 and thenozzle 5 is arranged on one lateral side of the shed and is directed to the other side of the shed, i.e. in the direction of the width of the fabric being formed, as usually. On the opposite side of the shed, i.e. in the direction of theweft 9 insertion into the shed (in the direction of picking theweft 9 through the shed) behind the woven fabric, aweft stop 7 and adetector 8 of theweft 9 removal are mounted on the machine frame. In the area between the pickingnozzle 5 and the proximal edge of the woven fabric, ameans 6 for interrupting theweft 9 is mounted on the machine frame. - The picking
nozzle 5 is with its hydraulic distribution system connected to the outlet of the fluid from thepump 4 of the weft insertion system, whereby the mechanical drive of thepump 4 of the weft insertion system is secured by connecting thepump 4 to anindividual drive 3. Theindividual drive 3 of thepump 4 of the weft insertion system is mechanically independent of the other subunits and elements of the hydraulic weaving machine. - The measuring
device 2 of the weft, theindividual drive 3 of thepump 4 of the weft insertion system, themeans 6 for interrupting theweft 9 , theweft stop 7 and thesensor 8 of theweft 9 removal are connected to thecontrol system 1 of the weaving machine. - The
control system 1 of the weaving machine controls the operation and coordination of the activities of the individual subunits and means of the weaving machine, so that fabric with the required parameters will be produced. That means that the standard weaving process takes place, in whichweft threads 9 are blown successively into the shed by the stream of the picking fluid ejected by the pickingnozzle 5 , whereby after each successful insertion, which is checked by theweft stop 7 on the other side of the shed, theweft 9 is separated from the other weft threads by themeans 6 for interrupting theweft 9 and subsequently theweft 9 is transferred by a beating-up mechanism to the fell of the woven fabric. In this manner, weaving cycles are continuously repeated and fabric is produced. - If the
weft stop 7 detects a state in which theweft 9 with its front end did not extend over the entire width of theweft 9 insertion, i.e. the entire width of the woven fabric enlarged by edge strips, in which theweft 9 exceeds the width of the woven fabric, it emits a signal about this state to thecontrol system 1 , which generates a signal to stop the machine. The signal to stop the machine is generated already during the same revolution of the machine in which the incorrectly insertedweft 9 was detected. - In addition, the above-mentioned signal to stop the machine prevents the interruption of the detected incorrectly inserted
weft 9 at the entrance into the shed by severing from the rest of the weft thread in themeasuring device 2 of theweft 9. In the process of normal weaving, this interruption is performed by themeans 6 for interrupting theweft 9 . - After stopping the machine, the machine operation is automatically reversed by the
control system 1 , i.e. the individual parts of the machine are put in reverse operation to such a position of the individual components of the machine (state), in which the shed with the detected defectively insertedweft 9 is opened, whereby this detected defectively insertedweft 9 is at the entrance into its shed still connected to theweft 9 supply on themeasuring device 2. - In this position of the individual subunits of the machine, at this state of the machine, one static insertion of the
new weft 9 is carried out through thus opened shed, by which means thenew weft 9 is inserted into the shed. Thenew weft 9 , which due to the fluid stream from the pickingnozzle 5 not only flies over the whole required width of the machine, but at the same time by acting dynamically on the previously defectively insertedweft 9 , to which the newly pickedweft 9 is still connected due to the suppression of the cutting off by themeans 6 for interrupting theweft 9 which still lies in the same shed, causes pulling out (ejection, expulsion, removal) of this incorrectly insertedweft 9 from the shed in the direction of the weft insertion. This automatic static insertion of thenew weft 9 is made possible by theindividual drive 3 of thepump 4 of the weft insertion system. - After inserting the
new weft 9 into the shed and therefore after the assumed pulling out (ejection, expulsion, removal) of the previously incorrectly insertedweft 9, thedetector 8 of theweft 9 removal, which is located on the side of the shed remote from the pickingnozzle 5 , is activated. Thedetector 8 of theweft 9 removal finds out howmany wefts 9 are physically present in the control zone, i.e. at the end of the shed behind theweft stop 7 . - If the removal of the defectively inserted
weft 9 has been successful, there must be only oneweft thread 9 present in the control zone and in that case thecontrol system 1 performs individual transfer of thisnew weft 9 to the fell of the fabric being formed and puts the hydraulic weaving machine into operating mode of standard fabric production, which means that automatic restart of the hydraulic weaving machine is performed and the machine continues producing the required fabric. - If there are more than one
weft thread 9 in the control zone, e.g., two or three weft threads, whereby this could be a loop formed by oneweft thread 9 when at least two parts of oneweft 9 are situated in the control zone, or, on the contrary, there is noweft 9 in the control zone, it means that the attempt to remove the defectively insertedweft 9 has failed. - After it has been found out that the attempt to remove the incorrectly inserted
weft 9 has failed, thecontrol system 1 decides on further action according to the nature of the failure. For example, if in the control zone there aremore weft threads 9 than one, the whole process, as well as the machine, is automatically stopped and signalling is initiated to show that the defectively insertedweft 9 has not been automatically removed. Similarly, if there is noweft 9 in the control zone, the whole process, as well as the machine, is automatically stopped and signalling is initiated to show that the new weft has not been inserted. - Although attempts to remove the incorrectly inserted weft can be repeated, it appears that repeating the process of automatic removal of the incorrectly inserted
weft 9 or uninsertednew weft 9 does not significantly improve the effectivity of the process and it is more favourable with respect to the effective use of the machine to call the operator to solve the problem already after the first failure and then restart the machine manually. - In the illustrated exemplary embodiment, the
detector 8 of theweft 9 removal comprises anultrasonic sensor 80 , which is mounted reversibly displaceably on the machine frame in the control zone transversely to the direction of the insertion (picking) of theweft threads 9. Below the control zone is located a collectingplate 81 , e.g. sheet metal, with alongitudinal opening 810. The collectingplate 81 extends from the beating-up position of the weavingreed 0, seeFig. 2 , as far as to the position of the weavingreed 0 at back dead centre below the space defined by the size of the shed in a vertical plane, seeFig. 3 . The position of the collectingplate 81 ensures that there are no parts of theweft 9 deposited on its surface. Moreover, the collectingplate 81 is during the machine operation very intensely sprayed by the disintegrating water jet of the hydraulic weft insertion system. Theultrasonic sensor 80 is mounted on a piston rod 820 of apneumatic cylinder 82 , which is via an unillustrated electro-pneumatic valve connected to a source of compressed air and to thecontrol system 1. Theultrasonic sensor 80 is further aligned with aair blower nozzle 83 , which is also connected to the source of compressed air whose supply is controlled by the above-mentioned electro-pneumatic valve. Theweft 9 properly inserted into the shed lies before being transferred to the fell of the woven fabric on the collectingplate 81 over thelongitudinal opening 810 formed in it. Once thepneumatic cylinder 82 has been started, thesupersonic sensor 80 is blown over by theair blower nozzle 83 , whereupon thesupersonic sensor 80 moves across the weft insertion path above the collectingplate 81 and thelongitudinal opening 810 formed in it. During this motion, in reality it represents a path of, e.g., approximately 50mm, theultrasonic sensor 80 moves at a certain distance above the collectingplate 81 as far as to the back position of the weavingreed 0 , as is shown inFig. 3 , scanning the impulses of ultrasound radiation reflected from thewefts 9 lying on the collectingplate 81 across thelongitudinal opening 810 . The observed number of impulses then substantially corresponds to the number ofwefts 9 , or, in other words, the threads lying in the control zone. Accordingly, thecontrol system 1 decides on further action, i.e. automatic restart or signaling failure status (due to the failure to remove the incorrectly insertedweft 9 or failure to insert a new weft 9 ), as has been described above. - In an unillustrated exemplary embodiment, the
detector 8 of theweft 9 removal comprises an optical sensor instead of anultrasonic sensor 80 , which is mounted either on the same movable structure as the above-describedultrasonic sensor 80 , or on another suitable structure allowing the optical sensor to move within the control zone. Preferably, the optical sensor is aligned with a cleaning device, e.g., a air blower nozzle, connected to the source of compressed air and serving to remove the picking fluid and impurities from the optical elements of the optical sensor. - Similarly, also the
ultrasonic detector 80 is in the unillustrated exemplary embodiment mounted on another suitable structure allowing the movement of theultrasonic sensor 80 within the control zone.
Claims (10)
- A method for removing a weft (9) incorrectly inserted by hydraulic picking into the shed of a hydraulic weaving machine, in which a control system for detecting incorrect weft (9) insertion performs the steps of stopping the machine, removing the incorrectly inserted weft (9) and restarting the machine to resume production mode, whereby during the same revolution of the machine in which the weft (9) was defectively inserted, a signal is generated by the control system (1) of the machine to stop the machine and thus interruption of the incorrectly inserted weft (9) is prevented at the entrance to the shed and subsequently, after the machine is stopped, the machine operation is reversed to a state of the machine with the shed in an open position in which the weft (9) was improperly inserted, whereupon a new weft (9) is inserted as static weft insertion without the motion of the opened branches of the warp and without the motion of the means for transferring the new weft (9) to the fell of the fabric being formed, by the new weft (9) insertion the previously defectively insterted weft (9) is removed from the opened shed and after that on the side of the shed remote from the picking nozzle (5) it is assessed whether the attempt to remove the weft has been successful and the machine is either restarted to resume production mode, or it is stopped and error signalling is initiated, characterized in that after the static weft insertion, at first the number of threads situated in the control zone is determined and subsequently, according to the observed number of threads in a control zone on the side of the shed remote from the picking nozzle, the control system (1) performs the transfer of the new weft (9) to the fell of the fabric being formed, whereupon the machine is either automatically restarted to production mode or the control system (1) stops the machine and initiates error signalling.
