<p>PURPOSE:To enable automatic change of control factor values for control of injection pressure, e.g. the detected sampling number at a time when the end part of a weft yarn arrives, the range of variation of control pressure and the upper and lower limit values of allowable injection pressure at a stage of test weaving and a stage of final weaving. CONSTITUTION:Control factors for controlling injection pressure, e.g. the sampling number for unifying arrival time values of the end part of a weft yarn detected by a weft yarn detector 6, the range of variation of control pressure and the upper and lower limit values of allowable injection pressure are stored in a control computer (C2). When directing switch from a stage of test weaving to a stage of final weaving, control factors for final weaving are selected and a detected injection pressure value obtained by pressure gages 13 and 14 at a time of the above-mentioned switch is used as the standard injection pressure.</p> |
