Abstract

A SHEET BREAK DETECTOR APPARATUS IS DISCLOSED FOR DETECTING A SHEET BREAK IN A DRYER SECTION OF A PAPER MACHINE. THE APPARATUS INCLUDES A VACUUM TRANSDUCER WHICH IS SENSITIVE TO THE VACUUM LEVEL WITHIN A VACUUM ROLL OF A DRYER SECTION. THE TRANSDUCER DETECTS ONLY A SUDDEN CHANGE IN VACUUM LEVEL WITHIN THE VACUUM ROLL RESULTING FROM A SHEET BREAK RATHER THAN A RELATIVELY GRADUAL CHANGE IN VACUUM LEVEL RESULTING FROM AN OPERATOR AUGMENTED VACUUM LEVEL CHANGE. A GUIDE DEVICE IS CONNECTED TO THE TRANSDUCER AND RESPONSIVE TO THE TRANSDUCER FOR REDIRECTING THE SHEET TO A BROKE CHUTE UPSTREAM RELATIVE TO THE TRANSDUCER WHEN THE TRANSDUCER DETECTS THE SUDDEN CHANGE IN VACUUM LEVEL. THE ARRANGEMENT IS SUCH THAT EXCESSIVE WIND- UP OF THE BROKEN SHEET AROUND A DRYER OF THE DRYER SECTION IS INHIBITED. (FIG. 3)
