  • warp-yarn types types of warp
  • warp yarn count warp thickness
  • warp-yarn types Types of warp (warp-yarn types):
  • Warp yarn count (yarn thickness)
  • Yarn count selected within a range from 5 to 160 (a higher yarn-count value implies finer yarn)
  • the stretch rate of the warp relies on the ratio of circumferential speeds between two rollers which are actively driven, and is represented by the equation: [(circumferential speed of a downstream roller / circumferential speed of an upstream roller) - 1] ⁇ 100 (%). Taking into consideration the fact that the warp-yarn sheet stretches while being transferred and the warp yarns shrink by being dried, this equation has been derived from prior experience and tests. Rather than performing the tension control by detecting the warp tensions, the tension control according to the stretch rate values derived from this equation is more stable and suitable.
  • the stretch rate between a sizing device and one of drying devices is increased such that a greater warp tension is applied, the quality of the warp may be lowered since the elongation of the warp may be lost.
  • the stretch rate between one of the drying devices and a winding device is preferably increased so as to apply greater warp tension. This achieves easier division of the dried warp-yarn sheet by a dividing rod disposed between the drying device and the winding device.
  • the temperatures of the drying devices refer to temperatures of drying cylinders.
  • the temperatures of the drying cylinders are controlled by on/off operations of electromagnetic on/off valves. By repeating these operations, the supply of high-pressure steam is regulated such that the temperatures are adjusted to the desired values.
  • a hot-air drying device having a heat exchanger disposed in the hot-air circulation path and a drying cylinder are provided.
  • the heat exchanger functions by using high-temperature steam or electric heat.
  • the temperature is adjusted to the desired value.
  • the temperature of size is controlled by on/off operations of an electromagnetic on/off valve. By repeating these operations, the supply of high-temperature steam to the size in a sizing tank is regulated such that the temperature of the size is adjusted to the desired value.
  • the squeezing pressure allows a slave-driven roller to urge against an active-driven roller via a hydraulic cylinder.
  • an effective force produced in a nip between the two rollers allows the size to penetrate into each yarn effectively and also to squeeze out excess size from each yarn. This force depends on the amount of size adhered to each yarn (amount of moisture).
  • a slave-driven roller is generally coated with high-friction elastic material, such as rubber. Accordingly, for some warp-yarn types or yarn thicknesses, the adhered amount of size is not lowered even if the squeezing pressure is set higher than a predetermined value, meaning that the squeezing pressure does not necessarily need to be set at a high value.
  • the squeezing pressure is set only for a second squeezing roller, the squeezing pressure may also be set for a first squeezing roller.
  • stored values of five parameters corresponding to warp specifications of each type of warp can be read and displayed, and moreover, may be changed to new values. Via a setting command, the stored values may be sent directly to the controller or may be sent to the controller after being changed to new values. Alternatively, the stored values of the five parameters may be sent to the controller simultaneously with the read-out and display of the values.

  • the warp yarns 2 pass through a nip between a take-up roller 28 and a press roller 29, and then through a tension roller 31 and a guide roller 46 to reach a winding beam 32 around which the warp yarns 2 are wound.
  • the take-up roller 28 and the winding beam 32 are respectively driven by a take-up motor 33 and a winding motor 34.
  • the rotational speed of the take-up roller 28 is substantially constant, whereas the rotational speed of the winding beam 32 becomes lower as the diameter of the wound warp yarns 2 increases.

  • Model numbers are registered in the model-number memory portion and are categorized according to warp specifications which include types of warp yarns 2 (warp-yarn types), yarn count, and the number of warp yarns 2. Furthermore, the model-number memory portion stores the model numbers and corresponding operating-condition values for the operating-condition parameters of each model number.
  • the standard-value/equation memory portion stores standard values for the operating conditions according to warp-yarn types and yarn count, and equations for calculating standard warp tensions based on warp-yarn types, yarn count, and the number of warp yarns 2.

Thus, the registered model number and its operating-condition values for the parameters of the model number are stored in the model-number memory portion. In response to a setting command sent from the input unit 39 operated by an operator, the setting unit 41 sends the selected operating-condition values to the controller 40, and the values are displayed in the display unit 43.
  • the controller 40 compares the warp tension of the warp yarns 2 detected by the tension detector 8 at the feeding side of the apparatus 1, i.e. the feeding tension, with a target warp-tension value. If there is a difference between the two tension values, the controller 40 regulates the supply of fluid 44 to the tension cylinder 7 so as to control the pressure in the cylinder 7. Accordingly, the frictional force between the shaft 3a of the feeding beam 3 and the braking pad 6 is adjusted by the cylinder 7 such that the feeding tension approximates the target warp tension.
  • the controller 40 compares the winding tension of the warp yarns 2 detected by the tension detector 35 at the winding side of the apparatus 1 with a target warp-tension value.

  • operating-condition values are read from the memory unit 42 by inputting a model number and are adjusted according to need before being sent to the controller 40
  • the operating-condition values may alternatively be sent to the controller 40 simultaneously with the read-out of the values from the memory unit 42. This reduces the workload of the operator, thus achieving simple operation of the input unit 39.
  • the display section for the standard values of the operating conditions and the adjusting section for the standard values i.e. the input unit for the operating-condition values
  • the display section and the adjusting section may be shifted to other positions on the screen, or may be provided in separate screens in a manner such that the operator can easily refer to the standard values when inputting numerical values via the adjusting section. This may prevent input errors in the operating-condition values.
  • the operating-condition data for the apparatus may be used as feedback for a process prior to the operation of the apparatus 1 or may be used for the weaving process that follows.
