ABSTRACT:
An apparatus and a method for detecting an abnormal load for a pressurizing apparatus is disclosed, in which a load change of the work is detected by use of an effective power detector or a mechanical strain detector, and values obtained by sampling at a plurality of points of pressurizing time are compared with a normal value already stored. The result of comparison is used to detect an abnormal load condition.
