Abstract: A variable pattern stamp has a base and a stamp plate unit. The base has smooth face and preferably is transparent. The stamp plate unit has multiple pattern plates and a protective sheet. The pattern plates have different or the same patterns and are preferably transparent. The protective sheet keeps the pattern plate from wrinkling, sticking to itself and getting dirty and losing its tackiness. After an individual pattern plate is selected and separated from adjacent pattern plates, the selected pattern plate is bonded detachably to the base and can be easily changed. People just buy one stamp and can stamp multiple patterns on papers and at the correct location.

Abstract: A flexible die is provided which incorporates a base die and a superimposed interchangeable cutting or embossing die. The base die is generally planar and is adapted to securely receiving the superimposed interchangeable die thereon. Protruding upwardly from the outer face of the base die is a raised cutting portion, a raised embossing portion, or both, which raised portion is adapted to cut, form, or emboss the outer periphery of a blank or substrate. The superimposed interchangeable die is generally planar, and includes a raised cutting or embossing portion protruding upwardly from the outer face thereof, which raised portion is adapted to cut, form or emboss a portion of the blank or substrate. At least a portion of the superimposed interchangeable die is adapted to be received onto at least a portion of the base die.

Abstract: A plate cylinder including a plate cylinder body; a first partially cylindrical image carrying shell and a second partially cylindrical image carrying shell, the shells being removably fastened to the plate cylinder body. Printing plates can be prefastened to the shells. The present invention also provides a method for attachment to a printing cylinder including the steps of mounting a first partially cylindrical shell and a second partially cylindrical shell to a printing cylinder body.
