PURPOSE:To carry out leaf aligning and perforation working at the same time to reduce steps by providing perforations in a blank when a signal of the blank counted by a photosensor coincides with a signal of a turned-on switch. CONSTITUTION:When blanks 6 being transferred on a locating table 10 reach a photosensor 15 section, a set of blanks 6 to be aligned is counted sequentially from 1-8, and when the blank in the order of turning-on of a switch 105 passes through a machine blade unit 18, a machine blade 25 holds down a roller 16 so that the respective blanks are perforated and leaf aligning and perforation are carried out at the same time to reduce steps. |
