<P>PROBLEM TO BE SOLVED: To provide a filter press dehydrator which can correctly detect and correct meandering of a filter cloth. <P>SOLUTION: A meandering correction mechanism 30 includes: a pair of guide rollers 31, 32 of which the shaft centers are arranged in postures parallel to each other, one of which comes in contact with a surface of the filter cloth 7 and the other of which comes in contact with a rear surface of the filter cloth 7; guide mechanisms 33, 34 which support a pair of guide rollers 31, 32 so as to be deflectable in order to hold the filter cloth 7 along a running direction while keeping the parallel posture; a pair of sensors 35, 36 which are respectively arranged near left and right terminal parts of the filter cloth 7 and detect deflection amount of the filter cloth 7 in a width direction accompanying the running of the filter cloth; and a driving mechanism which deflects a pair of guide rollers 31, 32 by driving the guide mechanisms 33, 34 based on difference between respective deflection amount detected by a pair of sensors 35, 36. <P>COPYRIGHT: (C)2013,JPO&INPIT |
