ABSTRACT OF THE DISCLOSURE A method and apparatus or detecting jam-ups of serially advancing blanks of which the method comprises storing a number corresponding to the length of the blanks in predetermined incre- ments, detecting a leading edge of such blanks, actuating a con- trol means by the detection of the leading edges which generates a digit corresponding to the predetermined increments, detecting a trailing edge of such blanks to deactuate the control means, comparing the stored number with the digits generated by the con- trol means, and stopping the blanks when the number of digits exceeds the stored number. Apparatus for carrying out the fore- going method preferably includes a storage circuit for the number corresponding to the blank length, a detector for detecting the leading and trailing edges of the blanks, a control means respon- sive to the detector for generating and storing digits correspond- ing to the blank length passing the detector, and a comparison circuit to determine when the number of digits exceeds the stored number and stopping the advance of blanks when this occurs.
