Abstract
There is disclosed a method and apparatus for accurately attaching a die plate to a cylinder segment in a manner that assures accurate registration of two die plates so attached to cylinder segments used in a cutting and creasing machine to cut or crease material passing through a nip formed therebetween. Pins on the arbor in the cutting and creasing machine accurately locate the cylinder segments. A 'Make Ready Machine' is used to accurately locate each die plate on a cylinder segment. The 'Make Ready Machine' includes axial and circumferential position indicators which are used to accurately place each cylinder segment in a predetermined position when it is mounted in the Make Ready Machine. Once the cylinder segment is in the predetermined position, the die plate is placed on the cylinder segment and moved until each of three lands on the die plate are in proper alignment with a view finder on the Make Ready Machine. The lands are formed on the die plate in a predetermined relationship with the lands which do the cutting and creasing. When the die plate is thus accurately located on the cylinder segment it is riveted in place, and any excess extending beyond the axial edges of the cylinder segment is removed. The cylinder segment with the die plate thus connected may then be placed in a cutting and creasing machine. When a second die plate is mounted to a second cylinder segment in the same manner, it may be mounted in a cutting and creasing machine to cooperate with the first die plate. Accurate registration of the die plates is assured because each is mounted in a predetermined position on a cylinder segment and each cylinder segment is in turn mounted in a predetermined position on the cutting and creasing machine.
