Disclosed is a method of punching a sheet using a register. Front and lateral marks (Q, R) of a sheet (S) are sensed, error values are calculated by a CPU (155), and front and lateral levers (135, 137) are actuated accordingly. Front and lateral edges (J, K) of the sheet (S) are not used as references, but front and lateral marks (Q, R) are used as references, so that a pattern (P) is brought into accurate conformity with a mold (131) and then cut off.
