ABSTRACT:
A press has a die unit, a feed mechanism and a table unit. The feed mechanism feeds a sheet of material to the die unit. The die unit has a punch and a die for punching first and second holes in the sheet. The punching axis of the punch is inclined at an acute angle with respect to the sheet. The table unit supports the die unit and rotates the die unit with respect to the sheet to direct the punching axis in different directions to form the first and second holes in different directions.
