<p>PURPOSE:To obtain a method for contour control of an extrusion rubber member and apparatus therefor wherein in control for weight per unit length, it can be thoroughly automated without assistance irrespective of a kind of a production member, and a sectional shape is also uniformed. CONSTITUTION:In a bias correction regulator 52, a mean of an input signal (deviation) is computed, and a signal (weight-converted value) for changing speed on a drawer conveyor 16 side is outputted according to means deviation. In a draw ratio correction regulator 62, a correction value for converging a difference (deviation) between a stationarily remaining actual draw ratio and a set ratio by controlling carrying speed on the drawer conveyor 13 side is computed, and inputted to a comparison operator 28 to which a mini continuous weigher weight-set value is inputted. A plasticially deformed amount to unvulcanized rubber 14 can be lessened by correction of the bias between continuous weighing and function wherein the draw ratio is converged to the set value. That is, a sectional shape which is a main point on quality and the weight control can be kept uniform.</p> |
