Automatic shape controlling device of rubber extruded article

PURPOSE:To reduce the incidence of non-conforming article by a method wherein the adjustment of shift is stopped when the detected value of the pressure of rubber in an extruded is below a set value at the time, when the molding of rubber extrusion molding such as automobile weatherstrip or the like is performed while the shift is being adjusted. CONSTITUTION:In the device concerned, in which rubber material fed from a material feeding device 2 is melted and extruded in the predetermined sectional shape from an extruder 1 and, after being heated with a microwave oscillator 4, introduced in a vulcanizing tank 3 for vulcanization in order to obtain rubber extruded article W, a shape detector for detecting the sectional shape of the vulcanized molded article W is provided near an unloader 6. When the detected value is off the range determined by the set rubber and lower bound values, command signal corresponding to the shift is outputted from a controlling device 22 so as to adjust the output of the microwave oscillator 4. Further, a pressure detector 13, which detects the pressure at the mouth piece 1a of the extruder 1, is provided so as to stop the output of the command signal, when the detected value is below the set value.
