Definitions

  • the invention relates to a method for avoiding tissue defects in smooth and pile tissues, e.g. due to a pattern-related change in operating parameters, e.g. a current target speed of the weaving machine or a current target operating pressure of the auxiliary nozzles arise during the weaving process.
  • a pattern-related change in operating parameters e.g. a current target speed of the weaving machine or a current target operating pressure of the auxiliary nozzles arise during the weaving process.
  • Fabric defects in the form of weft strips occur not only when the weaving machine is restarted, i.e. after it has come to a standstill, but also during the normal weaving process, when, depending on the types of weft thread to be processed, operating parameters of the weaving machine such as the speed and the operating pressure of the auxiliary blowing nozzles inevitably and automatically have to be changed and a weft thread entry is made during this change phase. It is known, for example, that the insertion of weft threads of different qualities, for example fiber yarn and chenille yarn, into the shed of an air-jet weaving machine requires different pressure parameters on the auxiliary blowing nozzles, or also necessitates a change in the weaving machine speed in order to reduce or increase the speed.
  • transitional operating conditions occur briefly during each parameter change within a weaving process.
  • a transitional operating condition is to be understood as the time period in the within the control z. B. is switched from a first effective target operating pressure of the auxiliary blowing nozzles to a second, a third or a further effective target operating pressure and the relevant parameter comes into effect.
  • a necessary change in the speed of the weaving machine can also be seen from this perspective.
  • the object of the invention is therefore to provide a process sequence for an air jet loom, according to which a change in operating parameters within a weaving program or variations in the pattern program during the weaving process do not allow errors in the fabric and a weaving machine stop based on the program changes or the pattern variation is excluded.
  • the weft thread insertion is interrupted when the shed is at a standstill or changing and only so-called fluidic or not fluidic wefts are delivered and the warp let-off and the goods take-off device is controlled depending on the number or the duration of the wasted shots delivered so that the fabric edge of the fabric is held in a position away from the stop position of the sley.
  • Design features of the main claim are shown in the dependent claims and in the following embodiment.
  • the weaving machine 1 has weft insertion means 2, a goods take-off device 3, a warp let-off device 4, a shedding device 5, a weaving machine drive 6, a compressed air supply 7 and optionally a terry cloth forming device 8.
  • a control 9 is assigned to the weaving machine 1, which triggers the weaving machine functions, weft insertion, warp unwinding and warp unwinding of the corresponding devices 2, 3, 4 via signal lines 10, 11, 12.
  • Via further signal lines 13, 13a; 14, 14a; 15, 15a; 16, 16a the shedding device 5, the weaving machine drive 6, the pressure supply 7 and optionally a terry cloth device are controlled according to a weaving program 17.
  • the weaving program 17 transmits program information (setpoints) to the control 9 via the signal lines 18 to 21, in which they are subjected to processing, in particular with regard to the setpoint speed of the weaving machine and the setpoint operating pressure of the weft insertion means.
  • program information setpoints
  • the weaving program 17 signals to the controller 9 that a weft thread type is pending for processing, which has different processing parameters compared to a thread type that has already been processed, and consequently a target speed other than the current target speed or a different target operating pressure than the current target -Operating pressure required, the controller 9 receives a signal via at least the lines 19, 20 of the weaving program, after which a speed and / or operating pressure change in the drive 6 and / or in the pressure supply 7 is initiated. With the signals to the controller 9, so-called transitional operating conditions are established in the weaving machine, during which the weft thread insertion is prevented and the weft thread insertion means 2 only emit so-called empty wefts.
  • the fabric take-off device and the warp let-off device are also influenced via the signal lines 11, 12 in such a way that the fabric stop edge of the fabric is held from a position remote from the stop position of the reed. This ensures that the reed does not strike the edge of the fabric during the transitional operating conditions, thus causing undesired tissue compression in the area of the edge of the fabric.
  • the shed forming device 5 can receive a signal from the controller 9 via the line 13, after which the heald frames form a closed shed; the heald frames are therefore in a specialist center position and therefore have no influence on the warp tension.
  • Such measures are of a technical nature, they support the effectiveness of the solution of the invention.
  • Transitional operating conditions are also set automatically when the freely programmable pattern parameters binding type and pile height undergo a change within the weaving program.
  • the weaving machine speed and operating pressure of the auxiliary nozzles have adjusted to the new setpoint, the end of the transitional operating conditions has been reached.
  • the goods edge of the fabric is returned to the position it had before the transitional operating conditions came into effect.
