ABSTRACT:
A method and system for manufacturing units of production enables the location of a splice to be accurately determined, so that only the unit of production containing the splice can be rejected without requiring additional units of production which are entirely free of defects to also be rejected. According to the method, first and second webs of material are spliced together so as to create a splice. The splice is marked with a magnetic marker. After the units of production are assembled, including a unit of production which contains the splice, the magnetic marker is magnetized. The magnetizing step occurs after the assembling step so that the orientation of the magnetic field remains parallel to the sensing direction until the magnetic field is detected. The magnetic marker is detected with a detector which has a plurality of closely spaced magnetic sensors. Based on the detecting step, the unit of production containing the splice is rejected and units of production which do not contain the splice are packaged.
